- Notice that square braces [] denote optional items. The first
- flag/option is a flag. The second is an option that has a numerical
- argument in the range 0 to 4. The third is a flag. the fourth is an
- option with an optional argument. The fourth is a flag.&nbsp; The
- flags and options can generally be in any order, but must be before
- the file name arguments. (For a few special tools you actually
- specify a sequence of flags and files where the flags apply just to
- the following file.) So example invocations may look like:<br>
- <br>
- &nbsp; tool -v testin testout<br>

- &nbsp; tool -f infile outfile<br>
- &nbsp; tool -f 45 infile outfile<br>
- &nbsp; tool -d 3 -f67 infile outfile<br>
- <p>In order to make use of the tools, it is necessary to keep track
- of where various files are, and what they are called. There are
- many possible ways of doing this. One way is to put each source
- profile and all its associated files (test charts, spectrometer
- values etc.) in one set of directories for each source profile
- type. Similarly the device profiles could be stored in a hierarchy
- of directories ordered by device type, media, resolution, device
- mode etc. Naturally you will want to set your $PATH so that you
- can run the tools from whichever directory you are in, as well as
- specify any necessary directory paths for file arguments so that
- the tools are able to open them.<br>
- </p>
- <p>Note that there are two ways the Argyll tools deal with filename
- extensions. In one you supply the extension (ie. you supply the
- whole file name), so the extension is up to you. In the other
- (used where one name is used for input and output files, or where
- there are multiple output files), the program adds the extension.
- In the documentation this should be indicated by calling it a
- "base name".<br>

+ then there are&nbsp; 5 flags/options, and two filename arguments.
+ Notice that square braces [] denote optional items. The first
+ flag/option is a flag. The second is an option that has a numerical
+ argument in the range 0 to 4. The third is a flag. the fourth is an
+ option with an optional argument. The fourth is a flag.&nbsp; The
+ flags and options can generally be in any order, but must be before
+ the file name arguments. (For a few special tools you actually
+ specify a sequence of flags and files where the flags apply just to
+ the following file.) So example invocations may look like:<br>
+ <br>
+ &nbsp; tool -v testin testout<br>
+ &nbsp; tool -d3 -M testin1 testout2<br>
+ &nbsp; tool -f infile outfile<br>
+ &nbsp; tool -f 45 infile outfile<br>
+ &nbsp; tool -d 3 -f67 infile outfile<br>
+ <p>In order to make use of the tools, it is necessary to keep track
+ of where various files are, and what they are called. There are
+ many possible ways of doing this. One way is to put each source
+ profile and all its associated files (test charts, spectrometer
+ values etc.) in one set of directories for each source profile
+ type. Similarly the device profiles could be stored in a hierarchy
+ of directories ordered by device type, media, resolution, device
+ mode etc. Naturally you will want to set your $PATH so that you
+ can run the tools from whichever directory you are in, as well as
+ specify any necessary directory paths for file arguments so that
+ the tools are able to open them.<br>
+ </p>
+ <p>Note that there are two ways the Argyll tools deal with filename
+ extensions. In one you supply the extension (ie. you supply the
+ whole file name), so the extension is up to you. In the other
+ (used where one name is used for input and output files, or where
+ there are multiple output files), the program adds the extension.
+ In the documentation this should be indicated by calling it a
+ "base name".<br>

+ and hence the white point tag, so that Absolute Colorimetric
+ rendering intent returns XYZ values under that illuminant using

+ The ICC specification have provision for hiding this difference in
+ illuminant by chromatically transforming the absolute values to be
+ functionally equivalent to having been measured using a D50
+ illuminant, and recording this transform in the ChromaticAdapation
+ ('chad') tag. This appears to motivated by the assumption that the

+ instrument that is to be worked around, as well as the limitation
+ of the ICC Absolute to Relative chromatic transformation being
+ based on the inferior non-cone space XYZ adaptation (so called

- <h1> <u>Installing the software on Apple OS X<br>
- </u></h1>
- <br>
- You will need to unpack the downloaded file in such a way that the
- files it contains end up in the location you have chosen to hold its
- contents.<br>
- <br>
- If you want to install it system wide, then you probably want to
- unpack it in the <i>/Applications</i> folder, so that it ends up in
- the <i>/Applications/Argyll_VX.X.X</i> folder.<br>
- Another option is just to install it somewhere under your $HOME
- folder, such as <span style="font-style: italic;">$HOME/</span><i>Argyll_VX.X.X</i>
- or <span style="font-style: italic;">$HOME/</span><i>bin/Argyll_VX.X.X</i>,
- depending on how you like to organize your applications and utility
- programs. ($HOME is the shell symbolic name for your home folder,
- typically /Users/<i>username</i>. Another abbreviation for it is the
- ~ character.)<br>
- <br>
- You can unpack it by control-click on the downloaded file and “Open
- With” BOMArchiveHelper or Archive Utility. Drag the resulting folder
- to where you want it, e.g. into <i>/Applications</i>, <i>$HOME</i>
- or <i>$HOME/bin</i>.<br>
- <br>
- Alternatively you can unpack it on the command line using&nbsp; the
- command <span style="font-weight: bold;">tar -zxf</span> <span
- style="font-weight: bold;">archivename.tgz</span>, which will
- create a folder <span style="font-weight: bold;">Argyll_VX.X.X</span>
- in your current folder, where X.X.X is the version number, and the
- executables will be in <span style="font-weight: bold;">Argyll_VX.X.X/bin</span>
- sub-folder.<br>
- <br>
- Open a Terminal shell. This will be in
- Applications-&gt;Utilities-&gt;Terminal (Dragging it to the dock is
- a good idea to make it more accessible).<br>
- <br>
- You should configure your $PATH environment variable to give the
- shell access to the executable from your command line environment
- without having to spell out the whole path every time, by editing
- your <span style="font-weight: bold;">.profile</span> file, which
- will be in your $HOME folder. You can open a graphical editor on
- this file by using the open command:<br>
- <br>
- &nbsp; open $HOME/.profile<br>
- <br>
- or alternatively, use some other text editor that you are familiar
- with.<br>
- <br>
- Add a line similar to the following line to your .profile file:<br>
- <br>
- &nbsp; PATH=$PATH:/Applications/Argyll_VX.X.X/bin<br>
- <br>
- where "/Applications/Argyll_VX.X.X/bin" is the path to the folder
- that contains the ArgyllCMS executables.<br>
- Save your changes and exit the editor.<br>
- <br>
- If you want further guidance in setting up and using a command line
- environment, then please consult an appropriate tutorial, e.g. &lt;<a
-href="http://heather.cs.ucdavis.edu/matloff/public_html/UnixAndC/Unix/ShellIntro.pdf">ShellIntro</a>&gt;.<br>
- <br>
- The .tgz file also contains several useful reference files (such as
- scanner chart recognition templates, sample illumination spectrum
- etc.) in the <b>ref</b> sub-folder, as well as all the current
- documentation in a <b>doc</b> sub-folder.<br>
- <br>
- For most devices there is nothing special to do. Plug in and go.
- Some devices may not work without some extra help though:<br>
- <h3><a name="ColorMunki"></a><span style="text-decoration:

- Some version of X-Rite's ColorMunki drivers released between 2009
- and 2011 install an X-Rite daemon that runs as root and grabs the
- device, preventing any other programs (such as Argyll) from opening
- them. Latter versions seem to be more cooperative, and don't suffer
- from this problem. There are three ways of working around this
- problem:<br>
- <br>
- 1) Turn off the X-Rite service for the ColorMunki. See &lt;<a

- <br>
- 2) Run all Argyll programs that need to access the instrument as
- root. For instance:<br>
- <br>
- &nbsp;&nbsp;&nbsp; sudo spotread<br>
- <br>
- and then you will be asked for the root password.<br>
- While these methods will work, they are inconvenient. <br>
- <br>
- 3) Alter the X-Rite drivers Daeomon so that it runs under your user
- account.<br>
- <br>
- To do this you need to edit the script that controls the X-Rite
- Daemon.<br>

<h3>Creating Device Links and Profiles<br>
</h3>

operation, by keeping computed values in case they can be used more
than once. The amount of memory used for caching these values is
pre-set within the inversion code, and by default is set to use half
- of
- the available RAM on the system, with a minimum of 50 Mbytes.<br>

<br>
The reverse cache size can be changed by setting an environment
- variable
- <span style="font-weight: bold;">ARGYLL_REV_CACHE_MULT</span> to a
- number greater or less than than 1.0 This will multiply the size of
- the
- cache by that number (i.e. 1.5 would increase the cache size by 50%,

<br>
If you find that <span style="font-weight: bold;">colprof</span>

is a sign of disk swapping, and that too much memory is being
requested.&nbsp; This can be because other applications are also
- using
- memory, or Argyll's default setting tries to use more memory than is
- actually available. You can try shutting down other applications
- when
- this happens, or you can <span style="font-weight: bold;">lower</span>

<br>
If you have a lot of memory available, you can try increasing the
cache size to use more of the available RAM (particularly if you get
- a
- "Warning - Reverse Cell Cache exhausted,
- processing in chunks" message during processing), but if you set it
- to
- a value too near 2.0 you risk disk swapping, which can slow progress
- to
- a crawl.<br>

<br>
If you have a lot of memory available, then a second adjustment that
- can make a great difference to the time taken
- in creating B2A tables is the resolution of the inverse lookup
- acceleration grid. The finer the grid, the less searching is needed
- to
- locate the input colorspace values that
- correspond to a target output color value, but the greater the
- memory
- used in this
- structure, and the greater the setup time needed to initialize the
- acceleration grid. The <span style="font-weight: bold;">ARGYLL_REV_ACC_GRID_RES_MULT</span>

+ the grid, the less searching is needed to locate the input
+ colorspace values that correspond to a target output color value,
+ but the greater the memory used in this structure, and the greater
+ the setup time needed to initialize the acceleration grid. The <span
+ style="font-weight: bold;">ARGYLL_REV_ACC_GRID_RES_MULT</span>
environment variable can alter the default resolution by a scale
factor. A value of 0.5 for instance, would halve the resolution
(typically meaning 1/8 th. the total number of grid entries and
memory), while a value of 2.0 would double it, typically resulting
- in 8
- times the memory usage. Increasing the resolution too much will
- reduce
- the available memory for the reverse cache, and greatly increase
- setup
- time.<br>
- <br>
- <h3>Setting an environment variable:</h3>
- <br>
- To set an environment variable an MSWindows DOS shell, either use
- set,
- e.g.;<br>
- <br>
- &nbsp;&nbsp;&nbsp; set ARGYLL_REV_CACHE_MULT=1.5<br>
- <br>
- which will set the value for that session, or set it in<br>
- <br>
- Control Panel-&gt;System-&gt;Advanced-&gt;Environment Variables..<br>
- <br>
- in either user or system variables.<br>
- <br>
- You can examine individual variables using<br>
- <br>
- &nbsp;&nbsp;&nbsp; echo %VARIABLE_NAME%<br>
- <br>
- or see all of them using<br>
- <br>
- &nbsp;&nbsp; set<br>
- <br>
- <br>
- For OS X or Linux, the exact procedure will depend on the shell you
- are
- running, but<br>
- is usually something like:<br>
- <br>
- &nbsp;&nbsp;&nbsp; export ARGYLL_REV_CACHE_MULT=1.5<br>
- or<br>
- &nbsp;&nbsp;&nbsp; set ARGYLL_REV_CACHE_MULT=1.5<br>
- or<br>
- &nbsp;&nbsp;&nbsp; ARGYLL_REV_CACHE_MULT=1.5<br>
- <br>
- and may need separately exporting, something like:<br>
- <br>
- &nbsp;&nbsp;&nbsp; export ARGYLL_REV_CACHE_MULT<br>
- <br>
- Generally it should be configured in the shell start-up
- script,&nbsp;
- if you
- want the setting to be used<br>
- for every session.<br>
- <br>
- You can examine individual variables using<br>
- <br>
- &nbsp;&nbsp;&nbsp; echo $VARIABLE_NAME<br>
- <br>
- or see all of them using<br>
+ in 8 times the memory usage. Increasing the resolution too much will
+ reduce the available memory for the reverse cache, and greatly
+ increase setup time.<br>

- <h3><a name="PM1"></a>Profiling Displays</h3>
- Argyll supports adjusting, calibrating and profiling of displays
- using one of a number of instruments - see <a
- href="instruments.html">instruments</a> for a current list.&nbsp;
- Adjustment and calibration are prior steps to profiling, in which
- the display is adjusted using it's screen controls,&nbsp; and then
- per channel lookup tables are created to make it meet a well behaved
- response of the desired type. The&nbsp; process following that of
- creating a display profile is then similar to that of all other
- output devices :- first a set of device colorspace test values needs
- to be created to exercise the display, then these values need to be
- displayed, while taking measurements of the resulting colors using
- the instrument. Finally, the device value/measured color values need
- to be converted into an ICC profile.<br>
- <br>
- <h3><a name="PM1a"></a>Checking you can access your display<br>
- </h3>
- You might first want to check that you are accessing and can
- calibrate your display. You can do this using the <a
- href="dispwin.html">dispwin</a><span style="font-weight: bold;"></span>
- tool<span style="font-weight: bold;">.</span> If you just run <span
- style="font-weight: bold;">dispwin</span> it will create a test
- window and run through a series of test colors before checking that
- the VideoLUT can be accessed by the display. If you invoke the usage
- for <span style="font-weight: bold;">dispwin</span> (by giving it

+ <h3><a name="PM1"></a>Profiling Displays</h3>
+ Argyll supports adjusting, calibrating and profiling of displays
+ using one of a number of instruments - see <a
+ href="instruments.html">instruments</a> for a current list.&nbsp;
+ Adjustment and calibration are prior steps to profiling, in which
+ the display is adjusted using it's screen controls,&nbsp; and then
+ per channel lookup tables are created to make it meet a well behaved
+ response of the desired type. The&nbsp; process following that of
+ creating a display profile is then similar to that of all other
+ output devices :- first a set of device colorspace test values needs
+ to be created to exercise the display, then these values need to be
+ displayed, while taking measurements of the resulting colors using
+ the instrument. Finally, the device value/measured color values need
+ to be converted into an ICC profile.<br>
+ <br>
+ <h3><a name="PM1a"></a>Checking you can access your display<br>
+ </h3>
+ You might first want to check that you are accessing and can
+ calibrate your display. You can do this using the <a
+ href="dispwin.html">dispwin</a><span style="font-weight: bold;"></span>
+ tool<span style="font-weight: bold;">.</span> If you just run <span
+ style="font-weight: bold;">dispwin</span> it will create a test
+ window and run through a series of test colors before checking that
+ the VideoLUT can be accessed by the display. If you invoke the usage
+ for <span style="font-weight: bold;">dispwin</span> (by giving it
+ an unrecognized option, e.g. <span style="font-weight: bold;">-?</span>)
+ then it will show a list of available displays next to the <span
+ style="font-weight: bold;"><span style="font-weight: bold;">-d</span></span>
+ flag. Make sure that you are accessing the display you intend to
+ calibrate and profile, and that the VideoLUT is effective (the <span
+ style="font-weight: bold;">-r</span> flag can be used to just run
+ the VideoLUT test). You can also try clearing the VideoLUTs using
+ the <span style="font-weight: bold;">-c</span> flag, and loading a

- <br>
- Once this is done, <a href="dispcal.html">dispcal</a> can be run to

- default, the brightness and white point will be kept the same as the
- devices natural brightness and white point. The default response
- curve is a gamma of 2.4, except for Apple OS X systems prior to 10.6
- where a gamma of 1.8 is the default. 2.4 is close to that of&nbsp;
- many monitors, and close to that of the sRGB colorspace. <br>
- <br>
- A typical calibration that leaves the brightness and white point
- alone, might be:<br>
- <br>
- <a href="dispcal.html">dispcal</a> -v TargetA<br>
- <br>
- which will result in a "TargetA.cal" calibration file, that can then
- be used during the profiling stage.<br>
- <br>
- If the absolutely native response of the display is desired during
- profiling, then calibration should be skipped, and the linear.cal
- file from the "ref" directory used instead as the argument to the -k
- flag of <span style="font-weight: bold;">dispread</span>.<br>
- <br>
- <b>Dispcal</b> will display a test window in the middle of the

- instrument on the display. You may need to make sure that the
- display cursor is not in the test window, and it may also be
- necessary to disable any screensaver and powersavers before starting
- the process, although both <span style="font-weight: bold;">dispcal</span>
- and <span style="font-weight: bold;">dispread</span> will attempt
- to do this for you. It's also highly desirable on CRT's, to clear
- your screen of any white or bright background images or windows
- (running your shell window with white text on a black background
- helps a lot here.), or at least keep any bright areas away from the
- test window, and be careful not to change anything on the display
- while the readings are taken. Lots of bright images or windows can
- affect the ability to measure the black point accurately, and
- changing images on the display can cause inconsistency in the
- readings,&nbsp; and leading to poor results.<span
- style="font-weight: bold;"></span> LCD displays seem to be less
- influenced by what else is on the screen.<br>
- <br>
- If <span style="font-weight: bold;">dispcal</span> is run without
- arguments, it will provide a usage screen. The <span
- style="font-weight: bold;">-c</span> parameter allows selecting a
- communication port for an instrument, or selecting the instrument
- you want to use,&nbsp; and the <a href="dispcal.html#d"><span
- style="font-weight: bold;">-d</span></a> option allows selecting
- a target display on a multi-display system. On some multi-monitor
- systems, it may not be possible to independently calibrate and
- profile each display if they appear as one single screen to the
- operating system, or if it is not possible to set separate video
- lookup tables for each display. You can change the position and size
- of the test window using the <a href="dispcal.html#P"><span
- style="font-weight: bold;">-P</span></a> parameter. You can
- determine how best to arrange the test window, as well as whether
- each display has separate video lookup capability, by experimenting
- with the <a href="dispwin.html">dispwin</a> tool. <br>
- <br>
- For a more detailed discussion on interactively adjusting the
- display controls using <span style="font-weight: bold;">dispcal</span>,
- see <a href="dispcal.html#Adjustment">dispcal-adjustment</a>. Once
- you have adjusted and calibrated your display, you can move on to

- <h4><a name="PM1c"></a>Adjusting, calibrating and profiling in one

- If a simple matrix/shaper display profile is all that is desired, <span
- style="font-weight: bold;">dispcal</span> can be used to do this,
- permitting display adjustment, calibration and profiling all in one
- operation. This is done by using the <span style="font-weight:

- <br>
- For more flexibility in creating a display profile, the separate
- steps of creating characterization test values using <span
- style="font-weight: bold;">targen</span>, reading them from the
- display using <span style="font-weight: bold;">dispread</span>, and
- then creating a profile using <span style="font-weight: bold;">colprof</span>
- are used. The following steps illustrate this:<br>
- <h4><a name="PM2"></a>Profiling in several steps: Creating display
- test values</h4>
- If the <span style="font-weight: bold;">dispcal</span> has not been
- used to create a display profile at the same time as adjustment and
- calibration, then it can be used to create a suitable set of
- calibration curves as the first step, or the calibration step can be
- omitted, and the display cansimply be profiled.<br>
- <br>
- The first step in profiling any output device, is to create a set of
- device colorspace test values. The important parameters needed are:
- <br>
- <ul>
- <li>What colorspace does the device use ?</li>
- <li>How many test patches do I want to use ?</li>
- <li>What information do I already have about how the device
- behaves ?</li>
- </ul>
- For a display device, &nbsp;the colorspace will be RGB. The number
- of test patches will depend somewhat on what quality profile you
- want to make, what type of profile you want to make, and how long
- you are prepared to wait when testing the display.<br>
- At a minimum, a few hundred values are needed. A matrix/shaper type
- of profile can get by with fewer test values, while a LUT based
- profile will give better results if more test values are used. A
- typical number might be 200-600 or so values, while 1000-2000 is not
- an unreasonable number for a high quality characterization of a
- display.<br>
- <br>
- To assist the choice of test patch values, it can help to have a
- rough idea of how the device behaves. This could be in the form of
- an ICC profile of a similar device, or a lower quality, or previous
- profile for that particular device. If one were going to make a very
- high quality LUT based profile, then it might be worthwhile to make
- up a smaller, preliminary shaper/matrix profile using a few hundred
- test points, before embarking on testing the device with several
- thousand.<br>
- <br>
- Lets say that we ultimately want to make a profile for the device
- "DisplayA", the simplest approach is to make a set of test values
- that is independent of the characteristics of the particular device:<br>
- <br>
- <a href="targen.html">targen</a> <a href="targen.html#v">-v</a>
- &nbsp;<a href="targen.html#d">-d3</a> <a href="targen.html#f">-f500</a>
- <a href="targen.html#p1">DisplayA</a><br>
- <br>
- If there is a preliminary or previous profile called "OldDisplay"
- available, and we want to try creating a "pre-conditioned" set of
- test values that will more efficiently sample the device response,
- then the following would achieve this:<br>
- <u><br>
- </u><a href="targen.html"> targen</a> <a href="targen.html#v">-v</a>
- &nbsp;<a href="targen.html#d">-d3</a> <a href="targen.html#f">-f500</a>
- <a href="targen.html#c">-cOldDisplay.icm</a> <a
- href="targen.html#p1">DisplayA</a><br>
- <br>
- The output of <b>targen</b> will be the file DisplayA.ti1,
- containing the device space test values, as well as expected CIE
- values used for chart recognition purposes.<br>
- <br>
- <h4><a name="PM3"></a>Profiling in several steps: Taking readings
- from a display</h4>
- First it is necessary to connect your measurement instrument to your
- computer, and check which communication port it is connected to. In
- the following example, it is assumed that the instrument is
- connected to the default port 1, which is either the first USB
- instrument found, or serial port found. Invoking dispread so as to
- display the usage information (by using a flag -? or --) will list
- the identified serial and USB ports, and their labels.<br>
- <br>
- <a href="dispread.html">dispread</a> <a href="dispread.html#v">-v</a>
- <a href="dispread.html#p1">DisplayA</a><br>
- <br>
- If we created a calibration for the display using <a
- href="dispcal.html">dispcal</a>, then we will want to use this
- when we take the display readings (e.g. TargetA.cal from the
- calibration example)..<br>
- <br>
- <a href="dispread.html">dispread</a> <a href="dispread.html#v">-v</a>
- <a href="dispread.html#k">-k TargetA.cal</a> <a
- href="dispread.html#p1">DisplayA</a><br>
- <br>
- <b>dispread</b> will display a test window in the middle of the
- screen, and issue a series of instructions about placing the
- instrument on the display. You may need to make sure that the
- display cursor is not in the test window, and it may also be
- necessary to disable any screensaver before starting the process.
- Exactly the same facilities are provided to select alternate
- displays using the <span style="font-weight: bold;">-d</span>
- parameter, and an alternate location and size for the test window
- using the <span style="font-weight: bold;">-P</span> parameter as
- with <span style="font-weight: bold;">dispcal</span>.<br>
- <h4><a name="PM4"></a>Profiling in several steps: Creating a display
- profile</h4>
- There are two basic choices of profile type for a display, a
- shaper/matrix profile, or a LUT based profile. They have different
- tradeoffs. A shaper/matrix profile will work well on a well behaved
- display, that is one that behaves in an additive color manner, will
- give very smooth looking results, and needs fewer test points to
- create. A LUT based profile on the other hand, will model any
- display behaviour more accurately, and can accommodate gamut mapping
- and different intent tables. Often it can show some unevenness and
- contouring in the results though.<br>
- <br>
- To create a matrix/shaper profile, the following suffices:<br>
- <br>
- <a href="colprof.html">colprof</a> <a href="colprof.html#v">-v</a>
- <a href="colprof.html#E">-D"Display A"</a> <a href="colprof.html#q">-qm</a>
- <a href="colprof.html#a">-as</a> <a href="colprof.html#p1">DisplayA</a><br>
- <br>
- For a LUT based profile, where gamut mapping is desired, then a
- source profile will need to be provided to define the source gamut.
- For instance, if the display profile was likely to be linked to a
- CMYK printing source profile, say "swop.icm" or "fogra39l.icm", then
- the following would suffice:<br>
- <br>
- <a href="colprof.html">colprof</a> <a href="colprof.html#v">-v</a>
- <a href="colprof.html#E">-D"Display A"</a> <a href="colprof.html#q">-qm</a>
- <a href="colprof.html#S">-S</a><a href="colprof.html#S">
- fogra39l.icm</a> <a href="colprof.html#c">-cpp</a> <a
- href="colprof.html#d">-dmt</a> <a href="colprof.html#p1">DisplayA</a><br>
- <br>
- Make sure you check the delta E report at the end of the profile
- creation, to see if the sample data and profile is behaving
- reasonably.<br>
- If a calibration file was used with <a href="dispread.html">dispread</a>,
- then it will be converted to a vcgt tag in the profile, so that the
- operating system or other system color tools load the lookup curves
- into the display hardware, when the profile is used.<br>
- <h4><a name="PM5"></a>Installing a display profile</h4>
- <a href="dispwin.html">dispwin</a> provides a convenient way of
- installing a profile as the default system profile for the chosen
- display:<br>
- <br>
- <a href="dispwin.html">dispwin</a> <a href="dispwin.html#I">-I</a>
- <a href="dispwin.html#p1">DisplayA.icm</a><br>
- <br>
- This also sets the display to the calibration contained in the
- profile. If you want to try out a calibration before installing the
- profile, using dispwin without the <span style="font-weight: bold;">-I</span>
- option will load a calibration (ICC profile or .cal file) into the
- current display.<br>
- <br>
- Some systems will automatically set the display to the calibration
- contained in the installed profile (ie. OS X), while on other
- systems (ie. MSWindows and Linux/X11) it is necessary to use some
- tool to do this. On MSWindows XP you could install the
- optional&nbsp; <span style="font-weight: bold;">Microsoft&nbsp;Color&nbsp;Control&nbsp;Panel&nbsp;Applet&nbsp;for&nbsp;Windows&nbsp;XP</span>
- available for download from Microsoft to do this, but&nbsp;<span
- style="font-weight: bold;">NOTE</span> however that it seems to
- have a <span style="font-weight: bold;">bug</span>, in that it
- sometimes associates the profiles with the <span
- style="font-weight: bold;">wrong monitor</span> entry. Other
- display calibration tools will often install a similar tool, so
- beware of there being multiple, competing programs. [ Commonly these
- will be in your Start-&gt;Programs-&gt;Startup folder. ]<br>
- On Microsoft Vista, you need to use dispwin -L or some other tool to
- load the installed profiles calibration at startup.<br>
- <br>
- To use dispwin to load the installed profiles calibration to the
- display, use<br>
- <br>
- <a href="dispwin.html">dispwin</a> <a href="dispwin.html#L">-L</a><br>
- <br>
- As per usual, you can select the appropriate display using the <a
- href="dispwin.html#d">-d</a> flag.<br>
- <br>
- This can be automated on MSWindows and X11/Linux by adding this
- command to an appropriate startup script.<br>
- More system specific details, including how to create such startup
- scripts are <a href="dispprofloc.html">here</a>. <br>
- <br>
- If you are using Microsoft <span style="font-weight: bold;">Vista</span>,
- there is a known <span style="font-weight: bold;">bug</span> in
- Vista that resets the calibration every time a fade-in effect is
- executed, which happens if you lock and unlock the computer, resume
- from sleep or hibernate, or User Access Control is activated. Using
- <a href="dispwin.html">dispwin</a> <a href="dispwin.html#L">-L</a>
- may not restore the calibration, because Vista filters out setting
- (what it thinks) is a calibration that is already loaded. Use <a
- href="dispwin.html">dispwin</a> <a href="dispwin.html#c">-c</a> <a
- href="dispwin.html#L">-L</a><span style="font-family: monospace;"></span>
- as a workaround, as this will first clear the calibration, then
- re-load the current calibration.<br>
- <br>
- On X11/Linux systems, you could try adding <a href="dispwin.html">dispwin</a>
- <a href="dispwin.html#L">-L</a> to your <span style="font-weight:
- bold;">~/.config/autostart</span> file, so that your window
- manager automatically sets calibration when it starts. If you are
- running XRandR 1.2, you might consider running the experimental <a
- href="dispwin.html#D">dispwin -E</a> in the background, as in its
- "daemon" mode it will update the profile and calibration in response
- to any changes in the the connected display.<br>
- <br>

- <br>
- All instruments depend on silicon sensors, and such sensors generate

- factored out of the measurements by a dark or black instrument
- calibration. The spectrometers in particular need this calibration
- before commencing each set of measurements. Often an instrument will

+ will apply to all of the following examples.)<br>
+ <br>
+ Once this is done, <a href="dispcal.html">dispcal</a> can be run to
+ guide you through the display adjustments, and then calibrate it. By
+ default, the brightness and white point will be kept the same as the
+ devices natural brightness and white point. The default response
+ curve is a gamma of 2.4, except for Apple OS X systems prior to 10.6
+ where a gamma of 1.8 is the default. 2.4 is close to that of&nbsp;
+ many monitors, and close to that of the sRGB colorspace. <br>
+ <br>
+ A typical calibration that leaves the brightness and white point
+ alone, might be:<br>
+ <br>
+ <a href="dispcal.html">dispcal</a> -v TargetA<br>
+ <br>
+ which will result in a "TargetA.cal" calibration file, that can then

+ <br>
+ If the absolutely native response of the display is desired during
+ profiling, then calibration should be skipped, and the linear.cal

+ <br>
+ <b>Dispcal</b> will display a test window in the middle of the

+ instrument on the display. You may need to make sure that the
+ display cursor is not in the test window, and it may also be

+ the process, although both <span style="font-weight: bold;">dispcal</span>
+ and <span style="font-weight: bold;">dispread</span> will attempt
+ to do this for you. It's also highly desirable on CRT's, to clear
+ your screen of any white or bright background images or windows
+ (running your shell window with white text on a black background
+ helps a lot here.), or at least keep any bright areas away from the
+ test window, and be careful not to change anything on the display
+ while the readings are taken. Lots of bright images or windows can
+ affect the ability to measure the black point accurately, and
+ changing images on the display can cause inconsistency in the
+ readings,&nbsp; and leading to poor results.<span
+ style="font-weight: bold;"></span> LCD displays seem to be less
+ influenced by what else is on the screen.<br>
+ <br>
+ If <span style="font-weight: bold;">dispcal</span> is run without

+ For more flexibility in creating a display profile, the separate
+ steps of creating characterization test values using <span
+ style="font-weight: bold;">targen</span>, reading them from the
+ display using <span style="font-weight: bold;">dispread</span>, and
+ then creating a profile using <span style="font-weight: bold;">colprof</span>
+ are used. The following steps illustrate this:<br>
+ <h4><a name="PM2"></a>Profiling in several steps: Creating display
+ test values</h4>
+ If the <span style="font-weight: bold;">dispcal</span> has not been
+ used to create a display profile at the same time as adjustment and
+ calibration, then it can be used to create a suitable set of
+ calibration curves as the first step, or the calibration step can be
+ omitted, and the display cansimply be profiled.<br>
+ <br>
+ The first step in profiling any output device, is to create a set of
+ device colorspace test values. The important parameters needed are:
+ <br>
+ <ul>
+ <li>What colorspace does the device use ?</li>
+ <li>How many test patches do I want to use ?</li>
+ <li>What information do I already have about how the device
+ behaves ?</li>
+ </ul>
+ For a display device, &nbsp;the colorspace will be RGB. The number
+ of test patches will depend somewhat on what quality profile you
+ want to make, what type of profile you want to make, and how long
+ you are prepared to wait when testing the display.<br>
+ At a minimum, a few hundred values are needed. A matrix/shaper type
+ of profile can get by with fewer test values, while a LUT based
+ profile will give better results if more test values are used. A
+ typical number might be 200-600 or so values, while 1000-2000 is not
+ an unreasonable number for a high quality characterization of a
+ display.<br>
+ <br>
+ To assist the choice of test patch values, it can help to have a
+ rough idea of how the device behaves. This could be in the form of
+ an ICC profile of a similar device, or a lower quality, or previous
+ profile for that particular device. If one were going to make a very
+ high quality LUT based profile, then it might be worthwhile to make
+ up a smaller, preliminary shaper/matrix profile using a few hundred
+ test points, before embarking on testing the device with several
+ thousand.<br>
+ <br>
+ Lets say that we ultimately want to make a profile for the device
+ "DisplayA", the simplest approach is to make a set of test values
+ that is independent of the characteristics of the particular device:<br>
+ <br>
+ <a href="targen.html">targen</a> <a href="targen.html#v">-v</a>
+ &nbsp;<a href="targen.html#d">-d3</a> <a href="targen.html#f">-f500</a>
+ <a href="targen.html#p1">DisplayA</a><br>
+ <br>
+ If there is a preliminary or previous profile called "OldDisplay"
+ available, and we want to try creating a "pre-conditioned" set of
+ test values that will more efficiently sample the device response,
+ then the following would achieve this:<br>
+ <u><br>
+ </u><a href="targen.html"> targen</a> <a href="targen.html#v">-v</a>
+ &nbsp;<a href="targen.html#d">-d3</a> <a href="targen.html#f">-f500</a>
+ <a href="targen.html#c">-cOldDisplay.icm</a> <a
+ href="targen.html#p1">DisplayA</a><br>
+ <br>
+ The output of <b>targen</b> will be the file DisplayA.ti1,
+ containing the device space test values, as well as expected CIE
+ values used for chart recognition purposes.<br>
+ <br>
+ <h4><a name="PM3"></a>Profiling in several steps: Taking readings
+ from a display</h4>
+ First it is necessary to connect your measurement instrument to your
+ computer, and check which communication port it is connected to. In
+ the following example, it is assumed that the instrument is
+ connected to the default port 1, which is either the first USB
+ instrument found, or serial port found. Invoking dispread so as to
+ display the usage information (by using a flag -? or --) will list
+ the identified serial and USB ports, and their labels.<br>
+ <br>
+ <a href="dispread.html">dispread</a> <a href="dispread.html#v">-v</a>
+ <a href="dispread.html#p1">DisplayA</a><br>
+ <br>
+ If we created a calibration for the display using <a
+ href="dispcal.html">dispcal</a>, then we will want to use this
+ when we take the display readings (e.g. TargetA.cal from the
+ calibration example)..<br>
+ <br>
+ <a href="dispread.html">dispread</a> <a href="dispread.html#v">-v</a>
+ <a href="dispread.html#k">-k TargetA.cal</a> <a
+ href="dispread.html#p1">DisplayA</a><br>
+ <br>
+ <b>dispread</b> will display a test window in the middle of the
+ screen, and issue a series of instructions about placing the
+ instrument on the display. You may need to make sure that the
+ display cursor is not in the test window, and it may also be
+ necessary to disable any screensaver before starting the process.
+ Exactly the same facilities are provided to select alternate
+ displays using the <span style="font-weight: bold;">-d</span>
+ parameter, and an alternate location and size for the test window
+ using the <span style="font-weight: bold;">-P</span> parameter as
+ with <span style="font-weight: bold;">dispcal</span>.<br>
+ <h4><a name="PM4"></a>Profiling in several steps: Creating a display
+ profile</h4>
+ There are two basic choices of profile type for a display, a
+ shaper/matrix profile, or a LUT based profile. They have different
+ tradeoffs. A shaper/matrix profile will work well on a well behaved
+ display, that is one that behaves in an additive color manner, will
+ give very smooth looking results, and needs fewer test points to
+ create. A LUT based profile on the other hand, will model any
+ display behaviour more accurately, and can accommodate gamut mapping
+ and different intent tables. Often it can show some unevenness and
+ contouring in the results though.<br>
+ <br>
+ To create a matrix/shaper profile, the following suffices:<br>
+ <br>
+ <a href="colprof.html">colprof</a> <a href="colprof.html#v">-v</a>
+ <a href="colprof.html#E">-D"Display A"</a> <a href="colprof.html#q">-qm</a>
+ <a href="colprof.html#a">-as</a> <a href="colprof.html#p1">DisplayA</a><br>
+ <br>
+ For a LUT based profile, where gamut mapping is desired, then a
+ source profile will need to be provided to define the source gamut.
+ For instance, if the display profile was likely to be linked to a
+ CMYK printing source profile, say "swop.icm" or "fogra39l.icm", then
+ the following would suffice:<br>
+ <br>
+ <a href="colprof.html">colprof</a> <a href="colprof.html#v">-v</a>
+ <a href="colprof.html#E">-D"Display A"</a> <a href="colprof.html#q">-qm</a>
+ <a href="colprof.html#S">-S</a><a href="colprof.html#S">

+ href="colprof.html#d">-dmt</a> <a href="colprof.html#p1">DisplayA</a><br>
+ <br>
+ A fallback to using a specific source profile/gamut is to use a
+ general compression percentage as a gamut mapping:<br>
+ <br>
+ <a href="colprof.html">colprof</a> <a href="colprof.html#v">-v</a>
+ <a href="colprof.html#E">-D"Display A"</a> <a href="colprof.html#q">-qm</a>

+ href="colprof.html#d">-dmt</a> <a href="colprof.html#p1">DisplayA</a><br>
+ <br>
+ Make sure you check the delta E report at the end of the profile
+ creation, to see if the sample data and profile is behaving
+ reasonably.<br>
+ If a calibration file was used with <a href="dispread.html">dispread</a>,
+ then it will be converted to a vcgt tag in the profile, so that the
+ operating system or other system color tools load the lookup curves
+ into the display hardware, when the profile is used.<br>
+ <h4><a name="PM5"></a>Installing a display profile</h4>
+ <a href="dispwin.html">dispwin</a> provides a convenient way of
+ installing a profile as the default system profile for the chosen
+ display:<br>
+ <br>
+ <a href="dispwin.html">dispwin</a> <a href="dispwin.html#I">-I</a>
+ <a href="dispwin.html#p1">DisplayA.icm</a><br>
+ <br>
+ This also sets the display to the calibration contained in the
+ profile. If you want to try out a calibration before installing the
+ profile, using dispwin without the <span style="font-weight: bold;">-I</span>
+ option will load a calibration (ICC profile or .cal file) into the
+ current display.<br>
+ <br>
+ Some systems will automatically set the display to the calibration
+ contained in the installed profile (ie. OS X), while on other
+ systems (ie. MSWindows and Linux/X11) it is necessary to use some
+ tool to do this. On MSWindows XP you could install the
+ optional&nbsp; <span style="font-weight: bold;">Microsoft&nbsp;Color&nbsp;Control&nbsp;Panel&nbsp;Applet&nbsp;for&nbsp;Windows&nbsp;XP</span>
+ available for download from Microsoft to do this, but&nbsp;<span
+ style="font-weight: bold;">NOTE</span> however that it seems to
+ have a <span style="font-weight: bold;">bug</span>, in that it
+ sometimes associates the profiles with the <span
+ style="font-weight: bold;">wrong monitor</span> entry. Other
+ display calibration tools will often install a similar tool, so
+ beware of there being multiple, competing programs. [ Commonly these
+ will be in your Start-&gt;Programs-&gt;Startup folder. ]<br>
+ On Microsoft Vista, you need to use dispwin -L or some other tool to
+ load the installed profiles calibration at startup.<br>
+ <br>
+ To use dispwin to load the installed profiles calibration to the
+ display, use<br>
+ <br>
+ <a href="dispwin.html">dispwin</a> <a href="dispwin.html#L">-L</a><br>
+ <br>
+ As per usual, you can select the appropriate display using the <a
+ href="dispwin.html#d">-d</a> flag.<br>
+ <br>
+ This can be automated on MSWindows and X11/Linux by adding this
+ command to an appropriate startup script.<br>
+ More system specific details, including how to create such startup
+ scripts are <a href="dispprofloc.html">here</a>. <br>
+ <br>
+ If you are using Microsoft <span style="font-weight: bold;">Vista</span>,
+ there is a known <span style="font-weight: bold;">bug</span> in
+ Vista that resets the calibration every time a fade-in effect is
+ executed, which happens if you lock and unlock the computer, resume
+ from sleep or hibernate, or User Access Control is activated. Using
+ <a href="dispwin.html">dispwin</a> <a href="dispwin.html#L">-L</a>
+ may not restore the calibration, because Vista filters out setting
+ (what it thinks) is a calibration that is already loaded. Use <a
+ href="dispwin.html">dispwin</a> <a href="dispwin.html#c">-c</a> <a
+ href="dispwin.html#L">-L</a><span style="font-family: monospace;"></span>
+ as a workaround, as this will first clear the calibration, then
+ re-load the current calibration.<br>
+ <br>
+ On X11/Linux systems, you could try adding <a href="dispwin.html">dispwin</a>
+ <a href="dispwin.html#L">-L</a> to your <span style="font-weight:
+ bold;">~/.config/autostart</span> file, so that your window
+ manager automatically sets calibration when it starts. If you are
+ running XRandR 1.2, you might consider running the experimental <a
+ href="dispwin.html#D">dispwin -E</a> in the background, as in its
+ "daemon" mode it will update the profile and calibration in response
+ to any changes in the the connected display.<br>

- <p>In some situation there is no access to a displays VideoLUT
- hardware, and this hardware is what is usually used to implement
- display calibration. This could be because the display is being
- accessed via a web server, or because the driver or windowing
- system doesn't support VideoLUT access.<br>
- </p>
- <p>There are two basic options in this situation:<br>
- </p>
- <p>&nbsp; 1) Don't attempt to calibrate, just profile the display.<br>
- &nbsp; 2) Calibrate, but incorporate the calibration in some other
- way in the workflow.<br>
- </p>
- <p>The first case requires nothing special - just skip calibration
- (see the previous section <a href="#PM7">Profiling in several
- steps: Creating display test values</a>).</p>
- <p> In the second case, there are three choices:<br>
- </p>
- <p>&nbsp;2a) Use dispcal to create a calibration and a quick profile
- that incorporates the calibration into the profile.<br>
- &nbsp;2b) Use dispcal to create the calibration, then dispread and
- colprof to create a profile, and then incorporate the calibration
- into the profile using applycal.<br>
- &nbsp;2c) Use dispcal to create the calibration, then dispread and
- colprof to create a profile, and then apply the calibration after
- the profile in a cctiff workflow.<br>
- </p>
- <p>The first case requires nothing special, use dispcal in a normal
- fashioned with the <span style="font-weight: bold;">-o</span>
- option to generate a quick profile.The profile created will <span
- style="text-decoration: underline;">not</span> contain a 'vcgt'
- tag, but instead will have the calibration curves incorporated
- into the profile itself. If calibration parameters are chosen that
- change the displays white point or brightness, then this will
- result in a slightly unusual profile that has a white point that
- does not correspond with device R=G=B=1.0. Some systems may not
- cope properly with this type of profile, and a general shift in
- white point through such a profile can create an odd looking
- display if it is applied to images but not to other elements on
- the display say as GUI decoration elements or other application
- windows.<br>

+ <h4><a name="PM7"></a>Calibrating and profiling a display that
+ doesn't have VideoLUT access.</h4>
+ <p>In some situation there is no access to a displays VideoLUT
+ hardware, and this hardware is what is usually used to implement
+ display calibration. This could be because the display is being
+ accessed via a web server, or because the driver or windowing
+ system doesn't support VideoLUT access.<br>
+ </p>
+ <p>There are two basic options in this situation:<br>
+ </p>
+ <p>&nbsp; 1) Don't attempt to calibrate, just profile the display.<br>
+ &nbsp; 2) Calibrate, but incorporate the calibration in some other
+ way in the workflow.<br>
+ </p>
+ <p>The first case requires nothing special - just skip calibration
+ (see the previous section <a href="#PM7">Profiling in several
+ steps: Creating display test values</a>).</p>
+ <p> In the second case, there are three choices:<br>
+ </p>
+ <p>&nbsp;2a) Use dispcal to create a calibration and a quick profile
+ that incorporates the calibration into the profile.<br>
+ &nbsp;2b) Use dispcal to create the calibration, then dispread and
+ colprof to create a profile, and then incorporate the calibration
+ into the profile using applycal.<br>
+ &nbsp;2c) Use dispcal to create the calibration, then dispread and
+ colprof to create a profile, and then apply the calibration after
+ the profile in a cctiff workflow.<br>
+ </p>
+ <p>The first case requires nothing special, use dispcal in a normal
+ fashioned with the <span style="font-weight: bold;">-o</span>
+ option to generate a quick profile.The profile created will <span
+ style="text-decoration: underline;">not</span> contain a 'vcgt'
+ tag, but instead will have the calibration curves incorporated
+ into the profile itself. If calibration parameters are chosen that
+ change the displays white point or brightness, then this will
+ result in a slightly unusual profile that has a white point that
+ does not correspond with device R=G=B=1.0. Some systems may not
+ cope properly with this type of profile, and a general shift in
+ white point through such a profile can create an odd looking
+ display if it is applied to images but not to other elements on
+ the display say as GUI decoration elements or other application
+ windows.<br>
+ </p>
+ <p>In the second case, the calibration file created using dispcal
+ should be provided to dispread using the <span
+ style="font-weight: bold;">-K</span> flag:<br>
+ </p>
+ <p><a href="dispread.html">dispread</a> <a href="dispread.html#v">-v</a>
+ <a href="dispread.html#K">-K TargetA.cal</a> <a
+ href="dispread.html#p1">DisplayA</a></p>
+ <p><span style="font-weight: bold;"></span>Create the profile as
+ usual using colprof. but note that colprof will ignore the
+ calibration, and that no 'vcgt' tag will be added to the profile.<br>
+ You can then use <a href="applycal.html">applycal </a>to combine
+ the calibration into the profile. Note that the resulting profile
+ will be slightly unusual, since the profile is not made completely
+ consistent with the effects of the calibration, and the device
+ R=G=B=1.0 probably not longer corresponds with the PCS white or
+ the white point.<br>
+ </p>
+ In the third case, the same procedure as above is used to create a
+ profile, but the calibration is applied in a raster transformation
+ workflow explicitly, e.g.:<br>

- If you have any doubts about the correctness of the chart

- <h4><a name="PS4"></a>Creating a scanner or camera input profile</h4>
- Similar to a display profile, an input profile can be either a
- shaper/matrix or LUT based profile. Well behaved input devices will
- probably give the best results with a shaper/matrix profile, and
- this may also be the best choice if your test chart has a small or
- unevenly distributed set of test patchs (ie. the IT8.7.2). If a
- shaper/matrix profile is a poor fit, consider using a LUT type
- profile.<br>
- <br>
- When creating a LUT type profile, there is the choice of XYZ or
- L*a*b* PCS (Device independent, Profile Connection Space). Often for
- input devices, it is better to choose the XYZ PCS, as this may be a
- better fit given that input devices are usually close to being
- linearly additive in behaviour.<br>
- <br>
- If the purpose of the input profile is to use it as a substitute for
- a colorimeter, then the <b>-u</b> flag should be used to avoid
- clipping values above the white point. Unless the shaper/matrix type
- profile is a very good fit, it is probably advisable to use a LUT
- type profile in this situation.<br>
- <br>
- To create a matrix/shaper profile, the following suffices:<br>
- <br>
- <a href="colprof.html">colprof</a> <a href="colprof.html#v">-v</a>
- <a href="colprof.html#E">-D"Scanner</a> <a href="colprof.html#E">A"</a>

- <br>
- For an XYZ PCS LUT based profile then the following would be used:<br>
- <br>
- <a href="colprof.html">colprof</a> <a href="colprof.html#v">-v</a>
- <a href="colprof.html#E">-D"Scanner A"</a> <a href="colprof.html#q">-qm</a>
- <a href="colprof.html#a">-ax</a> <a href="colprof.html#p1">scanner</a><br>
- <br>
- For the purposes of a poor mans colorimeter, the following would
- generally be used:<br>
- <br>
- <a href="colprof.html">colprof</a> <a href="colprof.html#v">-v</a>
- <a href="colprof.html#E">-D"Scanner A"</a> <a href="colprof.html#q">-qm</a>
- <a href="colprof.html#a">-ax</a> <a href="colprof.html#u">-u</a> <a
- href="colprof.html#p1">scanner</a><br>
- <br>
- Make sure you check the delta E report at the end of the profile
- creation, to see if the sample data and profile is behaving
- reasonably. Depending on the type of device, and the consistency of
- the readings, average errors of 5 or less, and maximum errors of 15
- or less would normally be expected. If errors are grossly higher
- than this, then this is an indication that something is seriously
- wrong with the device measurement, or profile creation.<br>
- <br>
- If profiling a <span style="font-weight: bold;">camera</span> in <span
- style="font-weight: bold;">RAW</span> mode, then there may be some
- advantage in creating a pure matrix only profile, in which it is
- assumed that the camera response is completely linear. This may
- reduce extrapolation artefacts. If setting the white point will be
- done in some application, then it may also be an advantage to use

- <h3><a name="PP1"></a>Profiling Printers<br>
- </h3>
- The overall process is to create a set of device measurement target
- values, print them out, measure them, and then create an ICC profile
- from the measurements. If the printer is an RGB based printer, then
- the process is only slightly more complicated than profiling a
- display. If the printer is CMYK based, then some additional
- parameters are required to set the total ink limit (TAC) and
- &nbsp;black generation curve.<br>
- <h4><a name="PP2"></a>Creating a print profile test chart</h4>
- The first step in profiling any output device, is to create a set of
- device colorspace test values. The important parameters needed are:<br>
- <ul>
- <li>What colorspace does the device use ?</li>
- <li>How many test patches do I want to use/what paper size do I
- want to use ?</li>
- <li>What instrument am I going to use to read the patches ?<br>
- </li>
- <li>If it is a CMYK device, what is the total ink limit ?<br>
- </li>
- <li>What information do I already have about how the device
- behaves ?</li>
- </ul>
- Most printers running through simple drivers will appear as if they
- are RGB devices. In fact there is no such thing as a real RGB
- printer, since printers use white media and the colorant must
- subtract from the light reflected on it to create color, but the
- printer itself turns the incoming RGB into the native print
- colorspace, so for this reason we will tell targen to use the "Print
- RGB" colorspace, so that it knows that it's really a subtractive
- media. Other drivers will drive a printer more directly, and will
- expect a CMYK profile. [Currently Argyll is not capable of creating
- an ICC profile for devices with more colorants than CMYK. When this
- capability is introduced, it will by creating an additional
- separation profile which then allows the printer to be treated as a
- CMY or CMYK printer.] One way of telling what sort of profile is
- expected for your device is to examine an existing profile for that
- device using <a href="http://www.argyllcms.com/doc/iccdump.html">iccdump</a>.<br>
- <br>
- The number of test patches will depend somewhat on what quality
- profile you want to make, how well behaved the printer is, as well
- as the effort needed to read the number of test values. Generally it
- is convenient to fill a certain paper size with the maximum number
- of test values that will fit.<br>
- <br>
- At a minimum, for an "RGB" device, a few hundred values are needed
- (400-1000). For high quality CMYK profiles, 1000-3000 is not an
- unreasonable number of patches.<br>
- <br>
- To assist the determination of test patch values, it can help to
- have a rough idea of how the device behaves, so that the device test
- point locations can be pre-conditioned. This could be in the form of
- an ICC profile of a similar device, or a lower quality, or previous
- profile for that particular device. If one were going to make a very
- high quality Lut based profile, then it might be worthwhile to make
- up a smaller, preliminary shaper/matrix profile using a few hundred
- test points, before embarking on testing the device with several
- thousand.<br>
- <br>
- The documentation for the <a
- href="http://www.argyllcms.com/doc/targen.html">targen</a> tool
- lists a <a href="http://www.argyllcms.com/doc/targen.html#Table">table</a>
- of paper sizes and number of &nbsp;patches for typical situations.<br>
- <br>
- For a CMYK device, a total ink limit usually needs to be specified.
- Sometimes a device will have a maximum total ink limit set by its
- manufacturer or operator, and some CMYK systems (such as chemical
- proofing systems) don't have any limit. Typical printing devices
- such as Xerographic printers, inkjet printers and printing presses
- will have a limit. The exact procedure for determining an ink limit
- is outside the scope of this document, but one way of going about
- this might be to generate some small (say a few hundred patches)
- with targen &amp; pritntarg with different total ink limits, and
- printing them out, making the ink limit as large as possible without
- striking problems that are caused by too much ink.<br>
- <br>
- Generally one wants to use the maximum possible amount of ink to
- maximize the gamut available on the device. For most CMYK devices,
- an ink limit between 200 and 400 is usual, but and ink limit of 250%
- or over is generally desirable for reasonably dense blacks and dark
- saturated colors. And ink limit of less than 200% will begin to
- compromise the fully saturated gamut, as secondary colors (ie
- combinations of any two primary colorants) will not be able to reach
- full strength.<br>
- <br>
- Once an ink limit is used in printing the characterization test
- chart for a device, it becomes a critical parameter in knowing what
- the characterized gamut of the device is. If after printing the test
- chart, a greater ink limit were to be used, the the software would
- effectively be extrapolating the device behaviour at total ink
- levels beyond that used in the test chart, leading to inaccuracies.<br>
- <br>
- Generally in Argyll, the ink limit is established when creating the
- test chart values, and then carried through the profile making
- process automatically. Once the profile has been made however, the
- ink limit is no longer recorded, and you, the user, will have to
- keep track of it if the ICC profile is used in any program than
- needs to know the usable gamut of the device.<br>
- <br>
- <br>
- Lets consider two devices in our examples, "PrinterA" which is an
- "RGB" device, and "PrinterB" which is CMYK, and has a target ink
- limit of 250%. <br>
- <br>
- The simplest approach is to make a set of test values that is
- independent of the characteristics of the particular device:<br>
- <br>
- <a href="targen.html">targen</a> <a href="targen.html#v">-v</a>
- &nbsp;<a href="targen.html#d">-d2</a> <a href="targen.html#f">-f1053</a>
- <a href="targen.html#p1">PrinterA</a><br>
- <br>
- <a href="targen.html">targen</a> <a href="targen.html#v">-v</a>
- &nbsp;<a href="targen.html#d">-d4</a> <a href="targen.html#l">-l260</a>
- <a href="targen.html#f">-f1053</a> <a href="targen.html#p1">PrinterB</a><br>
- <br>
- The number of patches chosen here happens to be right for an A4
- paper size being read using a Spectroscan instrument. See the <a
- href="targen.html#Table">table</a> in&nbsp; the <a
- href="targen.html">targen</a> documentation for some other
- suggested numbers.<br>
- <br>
- If there is a preliminary or previous profile called "OldPrinterA"
- available, and we want to try creating a "pre-conditioned" set of
- test values that will more efficiently sample the device response,
- then the following would achieve this:<u><br>
- </u><br>
- <a href="targen.html">targen</a> <a href="targen.html#v">-v</a>
- &nbsp;<a href="targen.html#d">-d2</a> <a href="targen.html#f">-f1053</a>

- OldPrinterB</a> <a href="targen.html#p1">PrinterB</a><br>
- <a href="targen.html#p1"></a><br>
- <br>
- The output of <b>targen</b> will be the file PrinterA.ti1 and
- PrinterB.ti1 respectively, containing the device space test values,
- as well as expected CIE values used for chart recognition purposes.<br>
- <br>
- <h4><a name="PP2b"></a>Printing a print profile test chart<br>
- <br>
- </h4>
- The next step is turn the test values in to a PostScript or TIFF
- raster test file that can printed on the device. The basic
- information that needs to be supplied is the type of instrument that
- will be used to read the patches, as well as the paper size it is to
- be formatted for.<br>

- <br>
- For using with a scanner as a colorimeter, the Gretag Spectroscan
- layout is suitable, but the <a href="printtarg.html#s">-s</a> flag
- should be used so as to generate a layout suitable for scan
- recognition, as well as generating the scan recognition template
- files. (You probably want to use less patches with <span
- style="font-weight: bold;">targen</span>, when using the <span
- style="font-weight: bold;">printtarg -s</span> flag, e.g. 1026
- patches for an A4R page, etc.) The following would be typical:<br>
- <br>
- <a href="printtarg.html">printtarg</a> <a href="printtarg.html#v">-v</a>
- <a href="printtarg.html#s">-s</a> <a href="printtarg.html#i">-iSS</a>
- <a href="printtarg.html#p">-pA4R</a> <a href="printtarg.html#p1">PrinterA</a><br>
- <span style="font-weight: bold;"><br>
- printtarg</span> reads the PrinterA.ti1 file, creates a
- PrinterA.ti2 file containing the layout information as well as the
- device values and expected CIE values, as well as a PrinterA.ps file
- containing the test chart. If the <span style="font-weight: bold;">-s</span>
- flag is used, one or more PrinterA.cht files is created to allow the
- <a href="scanin.html">scanin</a> program to recognize the chart.<br>
- <br>
- To create TIFF raster files rather than PostScript, use the <a
- href="printtarg.html#t"><span style="font-weight: bold;">-t</span></a>
- flag.<br>
- <br>
- <span style="font-weight: bold;">GSview</span> is a good program to
- use to check what the PostScript file will look like, without
- actually printing it out. You could also use <span
- style="font-weight: bold;">Photoshop</span> or <span
- style="font-weight: bold;">ImageMagick</span> for this purpose.<br>
- <br>
- The last step is to print the chart out.<br>
- <br>
- Using a suitable PostScript or raster file printing program,
- downloader, print the chart. If you are not using a TIFF test chart,
- and you do not have a PostScript capable printer, then an
- interpreter like GhostScript or even Photoshop could be used to
- rasterize the file into something that can be printed. Note that it
- is important that the PostScript interpreter or TIFF printing
- application and printer configuration is setup for a device
- profiling run, and that any sort of color conversion of color
- correction be turned off so that the device values in the PostScript
- or TIFF file are sent directly to the device. If the device has a
- calibration system, then it would be usual to have setup and
- calibrated the device before starting the profiling run, and to
- apply calibration to the chart values. If Photoshop was to be used,
- then either the chart needs to be a single page, or separate .eps or
- .tiff files for each page should be used, so that they can be
- converted and printed one at a time (see the <a
- href="printtarg.html#e">-e</a> and <a href="printtarg.html#t">-t</a>
- flags).<br>
- <br>
- <h4><a name="PP3"></a>Reading a print test chart using an instrument</h4>
- Once the test chart has been printed, the color of the patches needs
- to be read using a suitable instrument.<br>
- <br>
- Several different instruments are currently supported, some that
- need to be used patch by patch, some read a strip at a time, and
- some read a sheet at a time. See <a href="instruments.html">instruments</a>
- for a current list.<br>
- <br>
- The instrument needs to be connected to your computer before running
- the <a href="chartread.html">chartread</a> command. Both serial
- port and USB connected Instruments are supported. A serial port to
- USB adapter might have to be used if your computer doesn't have any
- serial ports, and you have a serial interface connected instrument.<br>
- <br>
- If you run <a href="chartread.html">chartread</a> so as to print
- out its usage message (ie. by using a <span style="font-weight:
- bold;">-?</span> or <span style="font-weight: bold;">--</span>
- flags), then it will list any identified serial ports or USB
- connected instruments, and their corresponding number for the <a
- href="chartread.html#c">-c</a> option. By default, <a
- href="chartread.html">chartread</a> will try to connect to the
- first available USB instrument, or an instrument on the first serial
- port.<br>
- <br>
- The only arguments required is to specify the basename of the .ti2
- file. If a non-default serial port is to be used, then the <span
- style="font-weight: bold;">-c</span> option would also be
- specified.<br>
- <br>
- &nbsp;e.g. for a Spectroscan on the second port:<br>
- <br>
- <a href="chartread.html">chartread</a> <a href="chartread.html#c">-c2</a>
- <a href="chartread.html#p1">PrinterA</a><br>
- <br>
- For a DTP41 to the default serial port:<br>
- <br>
- <a href="chartread.html">chartread</a><a href="chartread.html#i"></a>
- <a href="chartread.html#p1">PrinterA</a><br>
- <br>
- <span style="font-weight: bold;">chartread</span> will interactively
- prompt you through the process of reading each sheet or strip. See <a

- <h4><a name="PP4"></a>Reading a print test chart using a scanner or
- camera<br>
- </h4>
- <br>
- Argyll supports using a scanner or even a camera as a substitute for
- a colorimeter. While a scanner or camera is no replacement for a
- color measurement instrument, it may give acceptable results in some
- situations, and may give better results than a generic profile for a
- printing device.<br>
- <br>
- The main limitation of the scanner-as-colorimeter approach are:<br>
- <br>
- * The scanner dynamic range and/or precision may not match the
- printers or what is required for a good profile.<br>
- * The spectral interaction of the scanner test chart and printer
- test chart with the scanner spectral response can cause color
- errors.<br>
- * Spectral differences caused by different black amounts in the
- print test chart can cause color errors. <br>
- * The scanner reference chart gamut may be much smaller than the
- printers gamut, making the scanner profile too inaccurate to be
- useful. <br>
- <br>
- As well as some of the above, a camera may not be suitable if it
- automatically adjusts exposure or white point when taking a picture,
- and this behavior cannot be disabled.<br>
- <br>
- The end result is often a profile that has a noticeable color cast,
- compared to a profile created using a colorimeter or spectrometer.<br>
- <br>
- <br>
- It is assumed that you have created a scanner or camera profile
- following the <a
- href="http://www.argyllcms.com/doc/Scenarios.html#PS1">procedure</a>
- outline above. For best possible results it is advisable to both
- profile the scanner or camera, and use it in scanning the printed
- test chart, in as "raw" mode as possible (i.e. using 16 bits per
- component images, if the scanner or camera is capable of doing so;
- not setting white or black points, using a fixed exposure etc.). It
- is generally advisable to create a LUT type input profile, and use
- the <a href="http://www.argyllcms.com/doc/colprof.html#u">-u</a>
- flag to avoid clipping scanned value whiter than the input
- calibration chart.<br>
- <br>
- Scan or photograph your printer chart (or charts) on the scanner or
+
+
+
+ documentation</a>).<br>
+ <br>
+ To create the scanner .ti3 file, run the <b>scanin</b> tool as
+ follows (assuming an IT8 chart is being used):<br>
+ <br>
+ <a href="scanin.html"> scanin</a> -v scanner.tif It8.cht It8ref.txt<br>
+ <br>
+ "It8ref.txt" or "It8ref.cie" is assumed to be the name of the CIE
+ reference file supplied by the chart manufacturer. The resulting
+ file will be named "<b>scanner.ti3</b>".<br>
+ <br>
+ <span style="font-weight: bold;">scanin</span> will process 16 bit
+ per component .tiff files, which (if the scanner is capable of
+ creating such files),&nbsp; may improve the quality of the profile.
+ <br>
+ <br>
+ If you have any doubts about the correctness of the chart
+ recognition, or the subsequent profile's delta E report is unusual,
+ then use the scanin diagnostic flags <a href="scanin.html#d">-dipn</a>
+ and examine the <span style="font-weight: bold;">diag.tif</span>
+ diagnostic file, to make sure that the patches are identified and
+ aligned correctly. If you have problems getting good automatic
+ alignment, then consider doing a manual alignment by locating the
+ fiducial marks on your scan, and feeding them into scanin <a
+ href="scanin.html#F">-F</a> parameters. The fiducial marks should
+ be listed in a clockwise direction starting at the top left.<br>
+ <h4><a name="PS4"></a>Creating a scanner or camera input profile</h4>
+ Similar to a display profile, an input profile can be either a
+ shaper/matrix or LUT based profile. Well behaved input devices will
+ probably give the best results with a shaper/matrix profile, and
+ this may also be the best choice if your test chart has a small or
+ unevenly distributed set of test patchs (ie. the IT8.7.2). If a
+ shaper/matrix profile is a poor fit, consider using a LUT type
+ profile.<br>
+ <br>
+ When creating a LUT type profile, there is the choice of XYZ or
+ L*a*b* PCS (Device independent, Profile Connection Space). Often for
+ input devices, it is better to choose the XYZ PCS, as this may be a
+ better fit given that input devices are usually close to being
+ linearly additive in behaviour.<br>
+ <br>
+ If the purpose of the input profile is to use it as a substitute for
+ a colorimeter, then the <b>-u</b> flag should be used to avoid
+ clipping values above the white point. Unless the shaper/matrix type
+ profile is a very good fit, it is probably advisable to use a LUT
+ type profile in this situation.<br>
+ <br>
+ To create a matrix/shaper profile, the following suffices:<br>
+ <br>
+ <a href="colprof.html">colprof</a> <a href="colprof.html#v">-v</a>

+ <br>
+ For an XYZ PCS LUT based profile then the following would be used:<br>
+ <br>

+ <a href="colprof.html#E">-D"Scanner A"</a> <a href="colprof.html#q">-qm</a>
+ <a href="colprof.html#a">-ax</a> <a href="colprof.html#p1">scanner</a><br>
+ <br>
+ For the purposes of a poor mans colorimeter, the following would
+ generally be used:<br>
+ <br>
+ <a href="colprof.html">colprof</a> <a href="colprof.html#v">-v</a>
+ <a href="colprof.html#E">-D"Scanner A"</a> <a href="colprof.html#q">-qm</a>
+ <a href="colprof.html#a">-ax</a> <a href="colprof.html#u">-u</a> <a
+ href="colprof.html#p1">scanner</a><br>
+ <br>
+ Make sure you check the delta E report at the end of the profile
+ creation, to see if the sample data and profile is behaving
+ reasonably. Depending on the type of device, and the consistency of
+ the readings, average errors of 5 or less, and maximum errors of 15
+ or less would normally be expected. If errors are grossly higher
+ than this, then this is an indication that something is seriously
+ wrong with the device measurement, or profile creation.<br>
+ <br>
+ If profiling a <span style="font-weight: bold;">camera</span> in <span
+ style="font-weight: bold;">RAW</span> mode, then there may be some
+ advantage in creating a pure matrix only profile, in which it is
+ assumed that the camera response is completely linear. This may
+ reduce extrapolation artefacts. If setting the white point will be
+ done in some application, then it may also be an advantage to use
+ the <span style="font-weight: bold;">-u</span> flag and avoid
+ setting the white point to that of the profile chart:<br>

+ <h3><a name="PP1"></a>Profiling Printers<br>
+ </h3>
+ The overall process is to create a set of device measurement target
+ values, print them out, measure them, and then create an ICC profile
+ from the measurements. If the printer is an RGB based printer, then
+ the process is only slightly more complicated than profiling a
+ display. If the printer is CMYK based, then some additional
+ parameters are required to set the total ink limit (TAC) and
+ &nbsp;black generation curve.<br>
+ <h4><a name="PP2"></a>Creating a print profile test chart</h4>
+ The first step in profiling any output device, is to create a set of
+ device colorspace test values. The important parameters needed are:<br>
+ <ul>
+ <li>What colorspace does the device use ?</li>
+ <li>How many test patches do I want to use/what paper size do I
+ want to use ?</li>
+ <li>What instrument am I going to use to read the patches ?<br>
+ </li>
+ <li>If it is a CMYK device, what is the total ink limit ?<br>
+ </li>
+ <li>What information do I already have about how the device
+ behaves ?</li>
+ </ul>
+ Most printers running through simple drivers will appear as if they
+ are RGB devices. In fact there is no such thing as a real RGB
+ printer, since printers use white media and the colorant must
+ subtract from the light reflected on it to create color, but the
+ printer itself turns the incoming RGB into the native print
+ colorspace, so for this reason we will tell targen to use the "Print
+ RGB" colorspace, so that it knows that it's really a subtractive
+ media. Other drivers will drive a printer more directly, and will
+ expect a CMYK profile. [Currently Argyll is not capable of creating
+ an ICC profile for devices with more colorants than CMYK. When this
+ capability is introduced, it will by creating an additional
+ separation profile which then allows the printer to be treated as a
+ CMY or CMYK printer.] One way of telling what sort of profile is
+ expected for your device is to examine an existing profile for that
+ device using <a href="http://www.argyllcms.com/doc/iccdump.html">iccdump</a>.<br>
+ <br>
+ The number of test patches will depend somewhat on what quality
+ profile you want to make, how well behaved the printer is, as well
+ as the effort needed to read the number of test values. Generally it
+ is convenient to fill a certain paper size with the maximum number
+ of test values that will fit.<br>
+ <br>
+ At a minimum, for an "RGB" device, a few hundred values are needed
+ (400-1000). For high quality CMYK profiles, 1000-3000 is not an
+ unreasonable number of patches.<br>
+ <br>
+ To assist the determination of test patch values, it can help to
+ have a rough idea of how the device behaves, so that the device test
+ point locations can be pre-conditioned. This could be in the form of
+ an ICC profile of a similar device, or a lower quality, or previous
+ profile for that particular device. If one were going to make a very
+ high quality Lut based profile, then it might be worthwhile to make
+ up a smaller, preliminary shaper/matrix profile using a few hundred
+ test points, before embarking on testing the device with several
+ thousand.<br>
+ <br>
+ The documentation for the <a
+ href="http://www.argyllcms.com/doc/targen.html">targen</a> tool
+ lists a <a href="http://www.argyllcms.com/doc/targen.html#Table">table</a>
+ of paper sizes and number of &nbsp;patches for typical situations.<br>
+ <br>
+ For a CMYK device, a total ink limit usually needs to be specified.
+ Sometimes a device will have a maximum total ink limit set by its
+ manufacturer or operator, and some CMYK systems (such as chemical
+ proofing systems) don't have any limit. Typical printing devices
+ such as Xerographic printers, inkjet printers and printing presses
+ will have a limit. The exact procedure for determining an ink limit
+ is outside the scope of this document, but one way of going about
+ this might be to generate some small (say a few hundred patches)
+ with targen &amp; pritntarg with different total ink limits, and
+ printing them out, making the ink limit as large as possible without
+ striking problems that are caused by too much ink.<br>
+ <br>
+ Generally one wants to use the maximum possible amount of ink to
+ maximize the gamut available on the device. For most CMYK devices,
+ an ink limit between 200 and 400 is usual, but and ink limit of 250%
+ or over is generally desirable for reasonably dense blacks and dark
+ saturated colors. And ink limit of less than 200% will begin to
+ compromise the fully saturated gamut, as secondary colors (ie
+ combinations of any two primary colorants) will not be able to reach
+ full strength.<br>
+ <br>
+ Once an ink limit is used in printing the characterization test
+ chart for a device, it becomes a critical parameter in knowing what
+ the characterized gamut of the device is. If after printing the test
+ chart, a greater ink limit were to be used, the the software would
+ effectively be extrapolating the device behaviour at total ink
+ levels beyond that used in the test chart, leading to inaccuracies.<br>
+ <br>
+ Generally in Argyll, the ink limit is established when creating the
+ test chart values, and then carried through the profile making
+ process automatically. Once the profile has been made however, the
+ ink limit is no longer recorded, and you, the user, will have to
+ keep track of it if the ICC profile is used in any program than
+ needs to know the usable gamut of the device.<br>
+ <br>
+ <br>
+ Lets consider two devices in our examples, "PrinterA" which is an
+ "RGB" device, and "PrinterB" which is CMYK, and has a target ink
+ limit of 250%. <br>
+ <br>
+ The simplest approach is to make a set of test values that is
+ independent of the characteristics of the particular device:<br>
+ <br>
+ <a href="targen.html">targen</a> <a href="targen.html#v">-v</a>
+ &nbsp;<a href="targen.html#d">-d2</a> <a href="targen.html#f">-f1053</a>

+ <a href="targen.html#f">-f1053</a> <a href="targen.html#p1">PrinterB</a><br>
+ <br>
+ The number of patches chosen here happens to be right for an A4
+ paper size being read using a Spectroscan instrument. See the <a
+ href="targen.html#Table">table</a> in&nbsp; the <a
+ href="targen.html">targen</a> documentation for some other
+ suggested numbers.<br>
+ <br>
+ If there is a preliminary or previous profile called "OldPrinterA"
+ available, and we want to try creating a "pre-conditioned" set of
+ test values that will more efficiently sample the device response,
+ then the following would achieve this:<u><br>
+ </u><br>
+ <a href="targen.html">targen</a> <a href="targen.html#v">-v</a>
+ &nbsp;<a href="targen.html#d">-d2</a> <a href="targen.html#f">-f1053</a>

+ OldPrinterB</a> <a href="targen.html#p1">PrinterB</a><br>
+ <a href="targen.html#p1"></a><br>
+ <br>
+ The output of <b>targen</b> will be the file PrinterA.ti1 and
+ PrinterB.ti1 respectively, containing the device space test values,
+ as well as expected CIE values used for chart recognition purposes.<br>
+ <br>
+ <h4><a name="PP2b"></a>Printing a print profile test chart<br>
+ <br>
+ </h4>
+ The next step is turn the test values in to a PostScript or TIFF
+ raster test file that can printed on the device. The basic
+ information that needs to be supplied is the type of instrument that
+ will be used to read the patches, as well as the paper size it is to
+ be formatted for.<br>
+ <br>
+ For an X-Rite DTP41, the following would be typical:<br>

+ For a Gretag Eye-One Pro, the following would be typical:<br>
+ <br>
+ <a href="printtarg.html">printtarg</a> <a href="printtarg.html#v">-v</a>
+ <a href="printtarg.html#i">-ii1</a> <a href="printtarg.html#p">-pA4</a>
+ <a href="printtarg.html#p1">PrinterA</a><br>
+ <br>
+ For using with a scanner as a colorimeter, the Gretag Spectroscan
+ layout is suitable, but the <a href="printtarg.html#s">-s</a> flag
+ should be used so as to generate a layout suitable for scan
+ recognition, as well as generating the scan recognition template
+ files. (You probably want to use less patches with <span
+ style="font-weight: bold;">targen</span>, when using the <span
+ style="font-weight: bold;">printtarg -s</span> flag, e.g. 1026
+ patches for an A4R page, etc.) The following would be typical:<br>
+ <br>
+ <a href="printtarg.html">printtarg</a> <a href="printtarg.html#v">-v</a>

+ printtarg</span> reads the PrinterA.ti1 file, creates a

+ device values and expected CIE values, as well as a PrinterA.ps file
+ containing the test chart. If the <span style="font-weight: bold;">-s</span>
+ flag is used, one or more PrinterA.cht files is created to allow the
+ <a href="scanin.html">scanin</a> program to recognize the chart.<br>
+ <br>
+ To create TIFF raster files rather than PostScript, use the <a
+ href="printtarg.html#t"><span style="font-weight: bold;">-t</span></a>
+ flag.<br>
+ <br>
+ <span style="font-weight: bold;">GSview</span> is a good program to
+ use to check what the PostScript file will look like, without
+ actually printing it out. You could also use <span
+ style="font-weight: bold;">Photoshop</span> or <span
+ style="font-weight: bold;">ImageMagick</span> for this purpose.<br>
+ <br>
+ The last step is to print the chart out.<br>
+ <br>
+ Using a suitable PostScript or raster file printing program,
+ downloader, print the chart. If you are not using a TIFF test chart,
+ and you do not have a PostScript capable printer, then an
+ interpreter like GhostScript or even Photoshop could be used to
+ rasterize the file into something that can be printed. Note that it
+ is important that the PostScript interpreter or TIFF printing
+ application and printer configuration is setup for a device
+ profiling run, and that any sort of color conversion of color
+ correction be turned off so that the device values in the PostScript
+ or TIFF file are sent directly to the device. If the device has a
+ calibration system, then it would be usual to have setup and
+ calibrated the device before starting the profiling run, and to
+ apply calibration to the chart values. If Photoshop was to be used,
+ then either the chart needs to be a single page, or separate .eps or
+ .tiff files for each page should be used, so that they can be
+ converted and printed one at a time (see the <a
+ href="printtarg.html#e">-e</a> and <a href="printtarg.html#t">-t</a>
+ flags).<br>
+ <br>
+ <h4><a name="PP3"></a>Reading a print test chart using an instrument</h4>
+ Once the test chart has been printed, the color of the patches needs
+ to be read using a suitable instrument.<br>
+ <br>
+ Several different instruments are currently supported, some that
+ need to be used patch by patch, some read a strip at a time, and
+ some read a sheet at a time. See <a href="instruments.html">instruments</a>
+ for a current list.<br>
+ <br>
+ The instrument needs to be connected to your computer before running
+ the <a href="chartread.html">chartread</a> command. Both serial
+ port and USB connected Instruments are supported. A serial port to
+ USB adapter might have to be used if your computer doesn't have any
+ serial ports, and you have a serial interface connected instrument.<br>
+ <br>
+ If you run <a href="chartread.html">chartread</a> so as to print
+ out its usage message (ie. by using a <span style="font-weight:
+ bold;">-?</span> or <span style="font-weight: bold;">--</span>
+ flags), then it will list any identified serial ports or USB
+ connected instruments, and their corresponding number for the <a
+ href="chartread.html#c">-c</a> option. By default, <a
+ href="chartread.html">chartread</a> will try to connect to the
+ first available USB instrument, or an instrument on the first serial
+ port.<br>
+ <br>
+ The only arguments required is to specify the basename of the .ti2
+ file. If a non-default serial port is to be used, then the <span
+ style="font-weight: bold;">-c</span> option would also be
+ specified.<br>
+ <br>
+ &nbsp;e.g. for a Spectroscan on the second port:<br>
+ <br>
+ <a href="chartread.html">chartread</a> <a href="chartread.html#c">-c2</a>
+ <a href="chartread.html#p1">PrinterA</a><br>

+ <a href="chartread.html#p1">PrinterA</a><br>

- </h4>
- Creating an RGB based printing profile is very similar to creating a
- display device profile. For a CMYK printer, some additional
- information is needed to set the black generation.<br>
- <br>
- Where the resulting profile will be used conventionally (ie. using <a
- href="collink.html">collink</a> <a href="collink.html#s">-s</a>,
- or <a href="cctiff.html">cctiff</a> or most other "dumb" CMMs) it
- is important to specify that gamut mapping should be computed for
- the output (B2A) perceptual and saturation tables. This is done by
- specifying a device profile as the parameter to the <a
- href="colprof.html">colprof</a> <a href="colprof.html#S">-S</a>
- flag. When you intend to create a "general use" profile, it can be a
- good technique to specify the source gamut as the opposite type of
- profile to that being created, i.e. if a printer profile is being
- created, specify a display profile (e.g. sRGB) as the source gamut.
- If a display profile is being created, then specify a printer
- profile as the source (e.g. Figra, SWOP etc.).&nbsp; When linking to
- the profile you have created this way as the output profile, then
- use perceptual intent if the source is the opposite type, and
- relative colorimetric if it is the same type.<br>
- <br>
- "Opposite type of profile" refers to the native gamut of the device,
- and what its fundamental nature is, additive or subtractive. An
- emissive display will have additive primaries (R, G &amp; B), while
- a reflective print, will have subtractive primaries (C, M, Y &amp;
- possibly others), irrespective of what colorspace the printer is
- driven in (a printer might present an RGB interface, but internally
- this will be converted to CMY, and it will have a CMY type of
- gamut).&nbsp; Because of the complimentary nature of additive and
- subtractive device primary colorants, these types of devices have
- the most different gamuts, and hence need the most gamut mapping to
- convert from one colorspace to the other.<br>
- <br>
- If you are creating a profile for a specific purpose, intending to
- link it to a specific input profile, then you will get the best
- results by specifying that source profile as the source gamut.<br>

- is fine and a robust neutral balance is important, or less K if the
- screening is more visible and neutral balance is less critical. The

- <h4>Overriding the ink limit<br>

- Normally the total ink limit will be read from the <span

- set at a level 10% lower than the number used in creating the test

- Make sure you check the delta E report at the end of the profile
- creation, to see if the profile is behaving reasonably.<br>
- <br>
- One way of checking that your ink limit is not too high, is to use "<span
- style="font-weight: bold;">xicc -fif -ia</span>" to check, by
- setting different ink limits using the <span style="font-weight:
- bold;">-l</span> option, feeding Lab = 0 0 0 into it, and checking
- the resulting&nbsp; black point. Starting with the ink limit used
- with <span style="font-weight: bold;">targen</span> for the test
- chart, reduce it until the black point starts to be affected. If it
- is immediately affected by any reduction in the ink limit, then the
- black point may be improved by increasing the ink limit used to
- generate the test chart and then re-print and re-measuring it,
- assuming other aspects such as wetness, smudging, spreading or
- drying time are not an issue.<br>

- <h3><a name="PC1"></a>Calibrating Printers<br>
- </h3>
- <span style="font-weight: bold;">Profiling</span> creates a
- description of how a device behaves, while <span
- style="font-weight: bold;">calibration</span> on the other hand is
- intended to <span style="text-decoration: underline;">change</span>
- how a device behaves. Argyll has the ability to create per-channel
- device space calibration curves for print devices, that can then be
- used to improve the behavior of of the device, making a subsequent
- profile fit the device more easily and also allow day to day
- correction of device drift without resorting to a full re-profile.<br>
- <br>
- <span style="font-weight: bold;">NOTE:</span> Because calibration
- adds yet another layer to the way color is processed, it is
- recommended that it not be attempted until the normal profiling
- workflow is established, understood and verified.<br>
- <h4><a name="PC2"></a>Calibrated print workflows</h4>
- There are two main workflows that printer calibration curves can be
- applied to:<br>
- <br>
- <span style="text-decoration: underline;">Workflow <span
- style="font-weight: bold;">with</span> native calibration
- capability</span>:<br>
- <br>
- Firstly the printer itself may have the capability of using per
- channel calibration curves. In this situation, the calibration
- process will be largely independent of profiling. Firstly the
- printer is configured to have both its color management and
- calibration disabled (the latter perhaps achieved by loading linear
- calibration curves), and a print calibration test chart that
- consists of per channel color wedges is printed. The calibration
- chart is read and the resulting .ti3 file converted into calibration
- curves by processing it using <span style="font-weight: bold;">printcal</span>.
- The calibration is then installed into the printer. Subsequent
- profiling will be performed on the <span style="text-decoration:
- underline;">calibrated</span> printer (ie. the profile test chart
- will have the calibration curves applied to it by the printer, and
- the resulting ICC profile will represent the behavior of the
- calibrated printer.)<br>
- <br>
- <span style="text-decoration: underline;">Workflow <span
- style="font-weight: bold;">without</span> native calibration
- capability</span>:<br>
- <br>
- The second workflow is one in which the printer has no calibration
- capability itself. In this situation, the calibration process will
- have to be applied using the ICC color management tools, so careful
- coordination with profiling is needed. Firstly the printer is
- configured to have its color management disabled, and a print
- calibration test chart that consists of per channel color wedges is
- printed. The calibration chart is converted into calibration curves
- by reading it and then processing the resultant .ti3 using <span
- style="font-weight: bold;">printcal</span>,. During the subsequent
- <span style="text-decoration: underline;">profiling</span>, the
- calibration curves will need to be applied to the profile test chart
- in the process of using <span style="font-weight: bold;">printtarg</span>.
- Once the the profile has been created, then in subsequent printing
- the calibration curves will need to be applied to an image being
- printed either explicitly when using <span style="font-weight:
- bold;">cctiff</span> to apply color profiles <span
- style="text-decoration: underline;">and</span> calibration, <span
- style="font-weight: bold;">OR</span> by creating a version of the
- profile that has had the calibration curves incorporated into it
- using the <span style="font-weight: bold;">applycal</span> tool.
- The latter is useful when some CMM (color management module) other
- than <span style="font-weight: bold;">cctiff </span>is being used.<br>
- <br>
- Once calibration aim targets for a particular device and mode
- (screening, paper etc.) have been established, then the printer can
- be re-calibrated at any time to bring its per channel behavior back
- into line if it drifts, and the new calibration curves can be
- installed into the printer, or re-incorporated into the profile.
- &nbsp;
- <h4><a name="PC3"></a>Creating a print calibration test chart</h4>
- The first step is to create a print calibration test chart. Since
- calibration only creates per-channel curves, only single channel
- step wedges are required for the chart. The main choice is the
- number of steps in each wedge. For simple fast calibrations perhaps
- as few as 20 steps per channel may be enough, but for a better
- quality of calibration something like 50 or more steps would be a
- better choice.<br>
- <br>
- Let's consider two devices in our examples, "PrinterA" which is an
- "RGB" printer device, and "PrinterB" which is CMYK. In fact there is
- no such thing as a real RGB printer, since printers use white media
- and the colorant must subtract from the light reflected on it to
- create color, but the printer itself turns the incoming RGB into the
- native print colorspace, so for this reason we are careful to tell
- targen to use the "Print RGB" colorspace, so that it knows to create
- step wedges from media white to full colorant values.<br>
- <br>
- For instance, to create a 50 steps per channel calibration test
- chart for our RGB and CMYK devices, the following would be
- sufficient:<br>
- <br>
- <a href="targen.html">targen</a> <a href="targen.html#v">-v</a>
- &nbsp;<a href="targen.html#d">-d2</a> <a href="targen.html#s">-s50</a>
- <a href="targen.html#e">-e3</a> <a href="targen.html#f">-f0</a> <a
- href="targen.html#p1">PrinterA_c</a><br>
- <br>
- <a href="targen.html">targen</a> <a href="targen.html#v">-v</a>
- &nbsp;<a href="targen.html#d">-d4</a> <a href="targen.html#s">-s50</a>
- <a href="targen.html#e">-e4</a> <a href="targen.html#f">-f0</a> <a
- href="targen.html#p1">PrinterB_c</a><br>
- <a href="targen.html#p1"></a><br>
- For an outline of how to then print and read the resulting test
- chart, see&nbsp; <a href="Scenarios.html#PP2b">Printing a print
- profile test chart</a>, and <a href="Scenarios.html#PP3">Reading
- a print test chart using an instrument</a>. Note that the printer
- must be in an un-profiled and un-calibrated mode when doing this
- print. Having done this, there will be a PrinterA.ti3 or
- PrinterB.ti3 file containing the step wedge calibration chart
- readings.<br>
- <br>
- <span style="font-weight: bold;">NOTE</span> that if you are
- calibrating a raw printer driver, and there is considerable dot
- gain, then you may want to use the <a href="targen.html#p">-p</a>
- parameter to adjust the test chart point distribution to spread them
- more evenly in perceptual space, giving more accurate control over
- the calibration. Typically this will be a value greater than one for
- a device that has dot gain, e.g. values of 1.5, 2.0 or 2.5 might be
- good places to start. You can do a preliminary calibration and use
- the verbose output of printcal to recommend a suitable value for <span
- style="font-weight: bold;">-p</span>.<br>
- <h4><a name="PC4"></a>Creating a printer calibration<br>
- </h4>
- The <a href="printcal.html">printcal</a> tool turns a calibration
- chart <a href="File_Formats.html#.ti3">.ti3</a> file into a <a
- href="File_Formats.html#.cal">.cal</a> file. It has three main
- operating modes:- Initial calibration, Re-Calibration, and
- Verification. (A fourth mode, "Imitation" is very like Initial
- Calibration, but is used for establishing a calibration target that
- a similar printer can attempt to imitate.)<br>
- <br>
- The distinction between Initial Calibration and Re-Calibration is
- that in the initial calibration we establish the "aim points" or
- response we want out of the printer after calibration. There are
- three basic parameters to set this for each channel: Maximum level,
- minimum level, and curve shape.<br>
- <br>
- By default the maximum level will be set using a heuristic which
- attempts to pick the point when there is diminishing returns for
- applying more colorant. This can be overridden using the <span
- style="font-weight: bold;">-x# percent</span> option, where <span
- style="font-weight: bold;">#</span> represents the choice of
- channel this will be applied to. The parameter is the percentage of
- device maximum. <br>
- <br>
- The minimum level defaults to 0, but can be overridden using the <span
- style="font-weight: bold;">-n# deltaE</span> option. A minimum of
- 0 means that zero colorant will correspond to the natural media
- color, but it may be desirable to set a non-pure media color using
- calibration for the purposes of emulating some other media. The
- parameter is in Delta E units.<br>
- <br>
- The curve shape defaults to being perceptually uniform, which means
- that even steps of calibrated device value result in perceptually
- even color steps. In some situations it may be desirable to alter
- this curve (for instance when non color managed output needs to be
- sent to the calibrated printer), and a simple curve shape target can
- be set using the <span style="font-weight: bold;">-t# percent</span>
- parameter. This affects the output value at 50% input value, and
- represents the percentage of perceptual output. By default it is 50%
- perceptual output for 50% device input.<br>
- <br>
- Once a device has been calibrated, it can be re-calibrated to the
- same aim target.<br>
- <br>
- Verification uses a calibration test chart printed through the
- calibration, and compares the achieved response to the aim target.<br>
- <br>
- The simplest possible way of creating the <span style="font-weight:
- bold;">PrinterA.cal</span> file is:<br>
- <br>
- &nbsp; <a href="printcal.html">printcal</a> <a
- href="printcal.html#i">-i</a> <a href="colprof.html#p2">PrinterA_c</a><br>
- <br>
- For more detailed information, you can add the <span
- style="font-weight: bold;">-v</span> and <span
- style="font-weight: bold;">-p</span> flags:<br>
- <br>
- &nbsp; <a href="printcal.html">printcal</a> <a
- href="printcal.html#v">-v</a> <a href="printcal.html#p">-p</a> <a
- href="printcal.html#i">-i</a> <a href="colprof.html#p2">PrinterB_c</a><br>
- <br>
- (You will need to select the plot window and hit a key to advance
- past each plot).<br>
- <br>
- For re-calibration, the name of the previous calibration file will
- need to be supplied, and a new calibration<br>
- file will be created:<br>
- <br>
- &nbsp; <a href="printcal.html">printcal</a> <a
- href="printcal.html#v">-v</a> <a href="printcal.html#p">-p</a> <a
- href="printcal.html#r">-r</a> <a href="colprof.html#p1">PrinterB_c_old</a>
- <a href="colprof.html#p2">PrinterB_c_new</a><br>
- <br>
- Various aim points are normally set automatically by <span
- style="font-weight: bold;">printcal</span>, but these can be
- overridden using the <a href="colprof.html#x">-x</a>, <a
- href="colprof.html#n">-n</a> and <a href="colprof.html#t">-t</a>
- options. e.g. say we wanted to set the maximum ink for Cyan to 80%
- and Black to 95%, we might use:<br>
- <br>
- &nbsp; <a href="printcal.html">printcal</a> <a
- href="printcal.html#v">-v</a> <a href="printcal.html#p">-p</a> <a
- href="printcal.html#i">-i</a> <a href="colprof.html#x">-xc 80</a>
- <a href="colprof.html#x">-xk 95</a> <a href="colprof.html#p2">PrinterB_c</a><br>
- <br>
- <a href="colprof.html#p2"></a>
- <h4><a name="PC5"></a>Using a printer calibration</h4>
- The resulting calibration curves can be used with the following
- other Argyll tools:<br>
- <br>
+
+
+
+ and then used <a href="xicclu.html#g">xicclu</a> to explore the
+ effect of the parameters.<br>
+ <br>
+ For instance, say we have our CMYK .ti3 file <span
+ style="font-weight: bold;">PrinterB.ti3</span>. First we make a
+ preliminary profile called <span style="font-weight: bold;">PrinterBt</span>:<br>
+ <br>
+ copy PrinterB.ti3 PrinterBt.ti3&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (Use
+ "cp" on Linux or OSX of course.)<br>
+ <a href="colprof.html">colprof</a> <a href="colprof.html#v">-v</a>

+ href="colprof.html#c">-cmt</a> <a href="colprof.html#d">-dpp</a>
+ <a href="colprof.html#p1">PrinterBt</a><br>
+ <br>
+ Then see what the minimum black level down the neutral axis can be.
+ Note that we need to also set any ink limits we've decided on as
+ well (coloprof defaulting to 10% less than the value recorded in the
+ .ti3 file). In this example the test chart has a 300% total ink
+ limit, and we've decided to use 290%:<br>
+ <br>
+ <a href="xicclu.html">xicclu</a> <a href="xicclu.html#g">-g</a> <a
+ href="xicclu.html#k">-kz</a> <a href="xicclu.html#l">-l290</a> <a
+ href="xicclu.html#f">-fif</a> <a href="xicclu.html#i">-ir</a> <a
+ href="xicclu.html#p1">PrinterBt.icm</a><br>
+ <br>
+ Which might be a graph something like this:<br>
+ <br>
+ <img alt="Graph of CMYK neutral axis with minimum K"
+ src="Kgraph1.jpg" style="width: 250px; height: 250px;"><br>
+ <br>
+ Note&nbsp; how the minimum black is zero up to 93% of the
+ white-&gt;black L* curve, and then jumps up to 87%. This is because
+ we've reached the total ink limit, and K then has to be substituted
+ for CMY, to keep the total under the total ink limit.<br>
+ <br>
+ Then let's see what the maximum black level down the neutral axis
+ can be:<br>
+ <br>
+ <a href="xicclu.html">xicclu</a> <a href="xicclu.html#g">-g</a> <a
+ href="xicclu.html#k">-kx</a> <a href="xicclu.html#l">-l290</a> <a
+ href="xicclu.html#f">-fif</a> <a href="xicclu.html#i">-ir</a> <a
+ href="xicclu.html#p1">PrinterBt.icm</a><br>
+ <br>
+ Which might be a graph something like this:<br>
+ <br>
+ <img alt="Graph of CMYK neutral axis with maximum K"
+ src="Kgraph2.jpg" style="width: 250px; height: 250px;"><br>
+ <br>
+ Note how the CMY values are fairly low up to 93% of the
+ white-&gt;black L* curve (the low levels of CMY are helping set the
+ neutral color), and then they jump up. This is because we've reach
+ the point where black on it's own, isn't as dark as the color that
+ can be achieved using CMY and K. Because the K has a dominant effect
+ on the hue of the black, the levels of CMY are often fairly volatile
+ in this region.<br>
+ <br>
+ Any K curve we specify must lie between the black curves of the
+ above two graphs.<br>
+ <br>
+ Let's say we'd like to chose a moderate black curve, one that aims
+ for about equal levels of CMY and K. We should also aim for it to be
+ fairly smooth, since this will minimize visual artefacts caused by
+ the limited fidelity that profile LUT tables are able to represent
+ inside the profile.<br>
+ <br>
+ <img style="width: 340px; height: 258px;" alt="-k parameters"
+ src="Kparams.jpg"><br>
+ <br>
+ <br>
+ For minimum discontinuities we should aim for the curve to finish at
+ the point it has to reach to satisfy the total ink limit at 87%
+ curve and 93% black. For a first try we can simply set a straight
+ line to that point: <br>
+ <br>
+ <a href="xicclu.html">xicclu</a> <a href="xicclu.html#g">-g</a> <a
+ href="xicclu.html#k">-kp 0 0 .93 .87 1.0</a> <a

+ src="Kgraph3.jpg" style="width: 250px; height: 250px;"><br>
+ <br>
+ The black "curve" hits the 93%/87% mark well, but is a bit too far
+ above CMY, so we'll try making the black curve concave:<br>
+ <br>
+ <a href="xicclu.html">xicclu</a> <a href="xicclu.html#g">-g</a> <a

+ <h3><a name="PC1"></a>Calibrating Printers<br>
+ </h3>
+ <span style="font-weight: bold;">Profiling</span> creates a
+ description of how a device behaves, while <span
+ style="font-weight: bold;">calibration</span> on the other hand is
+ intended to <span style="text-decoration: underline;">change</span>
+ how a device behaves. Argyll has the ability to create per-channel
+ device space calibration curves for print devices, that can then be
+ used to improve the behavior of of the device, making a subsequent
+ profile fit the device more easily and also allow day to day
+ correction of device drift without resorting to a full re-profile.<br>
+ <br>
+ <span style="font-weight: bold;">NOTE:</span> Because calibration
+ adds yet another layer to the way color is processed, it is
+ recommended that it not be attempted until the normal profiling
+ workflow is established, understood and verified.<br>
+ <h4><a name="PC2"></a>Calibrated print workflows</h4>
+ There are two main workflows that printer calibration curves can be
+ applied to:<br>
+ <br>
+ <span style="text-decoration: underline;">Workflow <span
+ style="font-weight: bold;">with</span> native calibration
+ capability</span>:<br>
+ <br>
+ Firstly the printer itself may have the capability of using per
+ channel calibration curves. In this situation, the calibration
+ process will be largely independent of profiling. Firstly the
+ printer is configured to have both its color management and
+ calibration disabled (the latter perhaps achieved by loading linear
+ calibration curves), and a print calibration test chart that
+ consists of per channel color wedges is printed. The calibration
+ chart is read and the resulting .ti3 file converted into calibration
+ curves by processing it using <span style="font-weight: bold;">printcal</span>.
+ The calibration is then installed into the printer. Subsequent
+ profiling will be performed on the <span style="text-decoration:
+ underline;">calibrated</span> printer (ie. the profile test chart
+ will have the calibration curves applied to it by the printer, and
+ the resulting ICC profile will represent the behavior of the
+ calibrated printer.)<br>
+ <br>
+ <span style="text-decoration: underline;">Workflow <span
+ style="font-weight: bold;">without</span> native calibration
+ capability</span>:<br>
+ <br>
+ The second workflow is one in which the printer has no calibration
+ capability itself. In this situation, the calibration process will
+ have to be applied using the ICC color management tools, so careful
+ coordination with profiling is needed. Firstly the printer is
+ configured to have its color management disabled, and a print
+ calibration test chart that consists of per channel color wedges is
+ printed. The calibration chart is converted into calibration curves
+ by reading it and then processing the resultant .ti3 using <span
+ style="font-weight: bold;">printcal</span>,. During the subsequent
+ <span style="text-decoration: underline;">profiling</span>, the
+ calibration curves will need to be applied to the profile test chart
+ in the process of using <span style="font-weight: bold;">printtarg</span>.
+ Once the the profile has been created, then in subsequent printing
+ the calibration curves will need to be applied to an image being
+ printed either explicitly when using <span style="font-weight:
+ bold;">cctiff</span> to apply color profiles <span
+ style="text-decoration: underline;">and</span> calibration, <span
+ style="font-weight: bold;">OR</span> by creating a version of the
+ profile that has had the calibration curves incorporated into it
+ using the <span style="font-weight: bold;">applycal</span> tool.
+ The latter is useful when some CMM (color management module) other
+ than <span style="font-weight: bold;">cctiff </span>is being used.<br>
+ <br>
+ Once calibration aim targets for a particular device and mode
+ (screening, paper etc.) have been established, then the printer can
+ be re-calibrated at any time to bring its per channel behavior back
+ into line if it drifts, and the new calibration curves can be
+ installed into the printer, or re-incorporated into the profile.
+ &nbsp;
+ <h4><a name="PC3"></a>Creating a print calibration test chart</h4>
+ The first step is to create a print calibration test chart. Since
+ calibration only creates per-channel curves, only single channel
+ step wedges are required for the chart. The main choice is the
+ number of steps in each wedge. For simple fast calibrations perhaps
+ as few as 20 steps per channel may be enough, but for a better
+ quality of calibration something like 50 or more steps would be a
+ better choice.<br>
+ <br>
+ Let's consider two devices in our examples, "PrinterA" which is an
+ "RGB" printer device, and "PrinterB" which is CMYK. In fact there is
+ no such thing as a real RGB printer, since printers use white media
+ and the colorant must subtract from the light reflected on it to
+ create color, but the printer itself turns the incoming RGB into the
+ native print colorspace, so for this reason we are careful to tell
+ targen to use the "Print RGB" colorspace, so that it knows to create
+ step wedges from media white to full colorant values.<br>
+ <br>
+ For instance, to create a 50 steps per channel calibration test
+ chart for our RGB and CMYK devices, the following would be
+ sufficient:<br>
+ <br>
+ <a href="targen.html">targen</a> <a href="targen.html#v">-v</a>
+ &nbsp;<a href="targen.html#d">-d2</a> <a href="targen.html#s">-s50</a>
+ <a href="targen.html#e">-e3</a> <a href="targen.html#f">-f0</a> <a

+ <a href="targen.html#e">-e4</a> <a href="targen.html#f">-f0</a> <a
+ href="targen.html#p1">PrinterB_c</a><br>
+ <a href="targen.html#p1"></a><br>
+ For an outline of how to then print and read the resulting test
+ chart, see&nbsp; <a href="Scenarios.html#PP2b">Printing a print
+ profile test chart</a>, and <a href="Scenarios.html#PP3">Reading
+ a print test chart using an instrument</a>. Note that the printer
+ must be in an un-profiled and un-calibrated mode when doing this
+ print. Having done this, there will be a PrinterA.ti3 or
+ PrinterB.ti3 file containing the step wedge calibration chart
+ readings.<br>
+ <br>
+ <span style="font-weight: bold;">NOTE</span> that if you are
+ calibrating a raw printer driver, and there is considerable dot
+ gain, then you may want to use the <a href="targen.html#p">-p</a>
+ parameter to adjust the test chart point distribution to spread them
+ more evenly in perceptual space, giving more accurate control over
+ the calibration. Typically this will be a value greater than one for
+ a device that has dot gain, e.g. values of 1.5, 2.0 or 2.5 might be
+ good places to start. You can do a preliminary calibration and use
+ the verbose output of printcal to recommend a suitable value for <span
+ style="font-weight: bold;">-p</span>.<br>
+ <h4><a name="PC4"></a>Creating a printer calibration<br>
+ </h4>
+ The <a href="printcal.html">printcal</a> tool turns a calibration
+ chart <a href="File_Formats.html#.ti3">.ti3</a> file into a <a
+ href="File_Formats.html#.cal">.cal</a> file. It has three main
+ operating modes:- Initial calibration, Re-Calibration, and
+ Verification. (A fourth mode, "Imitation" is very like Initial
+ Calibration, but is used for establishing a calibration target that
+ a similar printer can attempt to imitate.)<br>
+ <br>
+ The distinction between Initial Calibration and Re-Calibration is
+ that in the initial calibration we establish the "aim points" or
+ response we want out of the printer after calibration. There are
+ three basic parameters to set this for each channel: Maximum level,
+ minimum level, and curve shape.<br>
+ <br>
+ By default the maximum level will be set using a heuristic which
+ attempts to pick the point when there is diminishing returns for
+ applying more colorant. This can be overridden using the <span
+ style="font-weight: bold;">-x# percent</span> option, where <span
+ style="font-weight: bold;">#</span> represents the choice of
+ channel this will be applied to. The parameter is the percentage of
+ device maximum. <br>
+ <br>
+ The minimum level defaults to 0, but can be overridden using the <span
+ style="font-weight: bold;">-n# deltaE</span> option. A minimum of
+ 0 means that zero colorant will correspond to the natural media
+ color, but it may be desirable to set a non-pure media color using
+ calibration for the purposes of emulating some other media. The
+ parameter is in Delta E units.<br>
+ <br>
+ The curve shape defaults to being perceptually uniform, which means
+ that even steps of calibrated device value result in perceptually
+ even color steps. In some situations it may be desirable to alter
+ this curve (for instance when non color managed output needs to be
+ sent to the calibrated printer), and a simple curve shape target can
+ be set using the <span style="font-weight: bold;">-t# percent</span>
+ parameter. This affects the output value at 50% input value, and
+ represents the percentage of perceptual output. By default it is 50%
+ perceptual output for 50% device input.<br>
+ <br>
+ Once a device has been calibrated, it can be re-calibrated to the
+ same aim target.<br>
+ <br>
+ Verification uses a calibration test chart printed through the
+ calibration, and compares the achieved response to the aim target.<br>
+ <br>
+ The simplest possible way of creating the <span style="font-weight:
+ bold;">PrinterA.cal</span> file is:<br>
+ <br>
+ &nbsp; <a href="printcal.html">printcal</a> <a
+ href="printcal.html#i">-i</a> <a href="colprof.html#p2">PrinterA_c</a><br>
+ <br>
+ For more detailed information, you can add the <span
+ style="font-weight: bold;">-v</span> and <span
+ style="font-weight: bold;">-p</span> flags:<br>
+ <br>

+ <br>
+ (You will need to select the plot window and hit a key to advance
+ past each plot).<br>
+ <br>
+ For re-calibration, the name of the previous calibration file will
+ need to be supplied, and a new calibration<br>
+ file will be created:<br>
+ <br>
+ &nbsp; <a href="printcal.html">printcal</a> <a

+ <a href="colprof.html#p2">PrinterB_c_new</a><br>
+ <br>
+ Various aim points are normally set automatically by <span
+ style="font-weight: bold;">printcal</span>, but these can be
+ overridden using the <a href="colprof.html#x">-x</a>, <a
+ href="colprof.html#n">-n</a> and <a href="colprof.html#t">-t</a>
+ options. e.g. say we wanted to set the maximum ink for Cyan to 80%

- style="font-weight: bold;">printtarg</span> <span
- style="font-weight: bold;">-I</span> or <span style="font-weight:

- <h3><a name="LP1"></a>Linking Profiles</h3>
- Two device profiles can be linked together to create a device link
- profile, than encapsulates a particular device to device transform.
- Often this step is not necessary, as many systems and tools will
- link two device profiles "on the fly", but creating a device link
- profile gives you the option of using "smart CMM" techniques, such
- as true gamut mapping, improved inverse transform accuracy, tailored
- black generation and ink limiting.<br>
- <br>
- The overall process is to link the input space and output space
- profiles using <a href="collink.html">collink</a>, creating a
- device to device link profile. The device to device link profile can
- then be used by cctiff (or other ICC device profile capable tools),
- to color correct a raster files.<br>
- <br>
- Three examples will be given here, showing the three different modes
- than <span style="font-weight: bold;">collink</span> supports.<br>
- <br>
- In <a href="collink.html#s">simple mode</a>, the two profiles are
- linked together in a similar fashion to other <span
- style="font-weight: bold;">CMMs</span> simply using the forward
- and backwards color transforms defined by the profiles. Any gamut
- mapping is determined by the content of the tables within the two
- profiles, together with the particular intent chosen. Typically the
- same intent will be used for both the source and destination
- profile:<br>

- In <a href="collink.html#g">gamut mapping mode</a>, the

- instead the gamut mapping between source and destination is tailored
- to the specific gamuts of the two profiles, and the intent parameter
- supplied to <span style="font-weight: bold;">collink</span>.
- Additionally, source and destination viewing conditions should be
- provided, to allow the color appearance space conversion to work as
- intended. The colorimetric B2A table in the destination profile is
- used, and this will determine any black generation and ink limiting:<br>

- evaluate what, if any appearance transformation is appropriate for
- your environment at a later stage. ]<br>
- <br>
- In <a href="collink.html#G">inverse output table gamut mapping mode</a>,
- the pre-computed intent mappings inside the profiles are not used,
- but instead the gamut mapping between source and destination is
- tailored to the specific gamuts of the two profiles, and the intent

- In addition, the B2A table is <span style="font-weight: bold;">not</span>
- used in the destination profile, but the A2B table is instead
- inverted, leading to improved transform accuracy, and in CMYK
- devices, allowing the ink limiting and black generation parameters
- to be set:<br>
- <br>
- For a CLUT table based RGB printer destination profile, the

- <br>
- For a CMYK profile, the total ink limit needs to be specified (a
- typical value being 10% less than the value used in creating the
- device test chart), and the type of black generation also needs to
- be specified:<br>

- Note that you should set the source (<a href="collink.html#c">-c</a>)
- and destination (<a href="collink.html#d">-d</a>) viewing conditions
- for the type of device the profile represents, and the conditions
- under which it will be viewed.<br>
- <br>
- <h3><a name="LP3"></a>Image dependent gamut mapping using device
- links<br>
- </h3>
- When images are stored in large gamut colorspaces (such as. L*a*b*,
- ProPhoto, scRGB etc.), then using the colorspace gamut as the source
- gamut for gamut mapping is generally a bad idea, as it leads to
- overly compressed and dull images. The correct approach is to use a
- source gamut that represents the gamut of the images themselves.
- This can be created using tiffgamut, and an example workflow is as
- follows:<br>
- <br>
- <a href="tiffgamut.html">tiffgamut</a> -f80 -pj -cmt ProPhoto.icm
- image.tif<br>
- <br>

- <a href="cctiff.html#p3">image.tif</a> <a
- href="cctiff.html#p4">printfile.tif</a><br>
- <br>
- The printfile.tif is then send to the printer without color
- management, (i.e. in the same way the printer characterization test
- chart was printed), since it is in the printers native colorspace.<br>
- <br>
- You can adjust how conservatively the image gamut is preserved using
- the tiffgamut -f parameter. Omitting it or using a larger value (up
- to 100) preserves the color gradations of even the lesser used
- colors, at the cost of compressing the gamut more.<br>
- Using a smaller value will preserve the saturation of the most
- popular colors, at the cost of not preserving the color gradations
- of less popular colors.<br>
- <br>
- You can create a gamut that covers a set of source images by
- providing more than one image file name to tiffgamut. This may be
- more efficient for a group of related images, and ensures that
- colors are transformed in exactly the same way for all of the
- images.<br>

- <br>

- <h5>1) How to display test patches.<br>

- An alternative when working with MadVR V 0.86.9 or latter, is to use

+ printarg during subsequent <span style="font-weight: bold;">profiling</span>
+ so that any ink limit calculations will reflect final device values,
+ while not otherwise using the calibration within the ICC workflow:<br>

+ This will cause the .ti2 and resulting .ti3 and ICC profiles to

+ compute final device value ink limits. The calibration curves must
+ also of course be installed into the printer. The means to do this
+ is currently outside the scope of Argyll (ie. either the print
+ system needs to be able to understand Argyll CAL format files, or
+ some tool will be needed to convert Argyll CAL files into the
+ printer calibration format).<br>
+ <br>
+ <br>
+ In a workflow <span style="font-weight: bold;">without</span>

+ <h4><a name="PC6"></a>How profile ink limits are handled when
+ calibration is being used.</h4>
+ Even though the profiling process is carried out on top of the
+ linearized device, and the profiling is generally unaware of the
+ underlying non-linearized device values, an exception is made in the
+ calculation of ink limits during profiling. This is made possible by
+ including the calibration curves in the profile charts .ti2 and
+ subsequent .ti3 file and resulting ICC profile <span
+ style="font-weight: bold;">'targ'</span> text tag, by way of the <span
+ style="font-weight: bold;">printtarg</span> <span
+ style="font-weight: bold;">-I</span> or <span style="font-weight:
+ bold;">-K</span> options. This is done on the assumption that the
+ physical quantity of ink is what's important in setting the ink
+ limit, and that the underlying non-linearized device values
+ represent such a physical quantity.<br>

+ <hr size="2" width="100%">
+ <h3><a name="LP1"></a>Linking Profiles</h3>
+ Two device profiles can be linked together to create a device link
+ profile, than encapsulates a particular device to device transform.
+ Often this step is not necessary, as many systems and tools will
+ link two device profiles "on the fly", but creating a device link
+ profile gives you the option of using "smart CMM" techniques, such
+ as true gamut mapping, improved inverse transform accuracy, tailored
+ black generation and ink limiting.<br>
+ <br>
+ The overall process is to link the input space and output space
+ profiles using <a href="collink.html">collink</a>, creating a
+ device to device link profile. The device to device link profile can
+ then be used by cctiff (or other ICC device profile capable tools),
+ to color correct a raster files.<br>
+ <br>
+ Three examples will be given here, showing the three different modes
+ than <span style="font-weight: bold;">collink</span> supports.<br>
+ <br>
+ In <a href="collink.html#s">simple mode</a>, the two profiles are
+ linked together in a similar fashion to other <span
+ style="font-weight: bold;">CMMs</span> simply using the forward
+ and backwards color transforms defined by the profiles. Any gamut
+ mapping is determined by the content of the tables within the two
+ profiles, together with the particular intent chosen. Typically the
+ same intent will be used for both the source and destination
+ profile:<br>
+ <br>
+ <a href="collink.html">collink</a> <a href="collink.html#v">-v</a>
+ <a href="collink.html#q">-qm</a> <a href="collink.html#s">-s</a> <a
+ href="collink.html#si">-ip</a> <a href="collink.html#so">-op</a>
+ <a href="collink.html#p1">SouceProfile.icm</a> <a
+ href="collink.html#p2">DestinationProfile.icm</a> <a
+ href="collink.html#p3">Source2Destination.icm</a><br>
+ <br>
+ <br>
+ In <a href="collink.html#g">gamut mapping mode</a>, the
+ pre-computed intent mappings inside the profiles are not used, but
+ instead the gamut mapping between source and destination is tailored
+ to the specific gamuts of the two profiles, and the intent parameter
+ supplied to <span style="font-weight: bold;">collink</span>.
+ Additionally, source and destination viewing conditions should be
+ provided, to allow the color appearance space conversion to work as
+ intended. The colorimetric B2A table in the destination profile is
+ used, and this will determine any black generation and ink limiting:<br>
+ <br>
+ <a href="collink.html">collink</a> <a href="collink.html#v">-v</a>
+ <a href="collink.html#q">-qm</a> <a href="collink.html#g">-g</a> <a

+ <a href="collink.html#p2">DestinationProfile.icm</a> <a
+ href="collink.html#p3">Source2Destination.icm</a><br>
+ <br>
+ [ If your viewing environment for the display and print doesn't
+ match the ones implied by the <a href="colprof.html#c">-cmt</a> and
+ <a href="colprof.html#d">-dpp</a> options, leave them out, and
+ evaluate what, if any appearance transformation is appropriate for
+ your environment at a later stage. ]<br>
+ <br>
+ In <a href="collink.html#G">inverse output table gamut mapping mode</a>,
+ the pre-computed intent mappings inside the profiles are not used,
+ but instead the gamut mapping between source and destination is
+ tailored to the specific gamuts of the two profiles, and the intent
+ parameter supplied to <span style="font-weight: bold;">collink</span>.
+ In addition, the B2A table is <span style="font-weight: bold;">not</span>
+ used in the destination profile, but the A2B table is instead
+ inverted, leading to improved transform accuracy, and in CMYK
+ devices, allowing the ink limiting and black generation parameters
+ to be set:<br>
+ <br>
+ For a CLUT table based RGB printer destination profile, the
+ following would be appropriate:<br>
+ <br>
+ <a href="collink.html">collink</a> <a href="collink.html#v">-v</a>
+ <a href="collink.html#q">-qm</a> <a href="collink.html#G">-G</a> <a

+ <a href="collink.html#p2">RGBDestinationProfile.icm</a> <a
+ href="collink.html#p3">Source2Destination.icm</a><br>
+ <br>
+ For a CMYK profile, the total ink limit needs to be specified (a
+ typical value being 10% less than the value used in creating the
+ device test chart), and the type of black generation also needs to
+ be specified:<br>
+ <br>
+ <a href="collink.html">collink</a> <a href="collink.html#v">-v</a>
+ <a href="collink.html#q">-qm</a> <a href="collink.html#G">-G</a> <a

+ <a href="collink.html#p2">CMYKDestinationProfile.icm</a> <a
+ href="collink.html#p3">Source2Destination.icm</a><br>
+ <br>
+ Note that you should set the source (<a href="collink.html#c">-c</a>)
+ and destination (<a href="collink.html#d">-d</a>) viewing conditions
+ for the type of device the profile represents, and the conditions
+ under which it will be viewed.<br>
+ <br>
+ <h3><a name="LP3"></a>Image dependent gamut mapping using device
+ links<br>
+ </h3>
+ When images are stored in large gamut colorspaces (such as. L*a*b*,
+ ProPhoto, scRGB etc.), then using the colorspace gamut as the source
+ gamut for gamut mapping is generally a bad idea, as it leads to
+ overly compressed and dull images. The correct approach is to use a
+ source gamut that represents the gamut of the images themselves.
+ This can be created using tiffgamut, and an example workflow is as
+ follows:<br>
+ <br>
+ <a href="tiffgamut.html">tiffgamut</a> -f80 -pj -cmt ProPhoto.icm
+ image.tif<br>
+ <br>
+ <a href="collink.html">collink</a> <a href="collink.html#v">-v</a>
+ <a href="collink.html#q">-qh</a> <a href="collink.html#G">-G</a> <a
+ href="collink.html#Gp">image.gam</a> <a href="collink.html#si">-ip</a>
+ <a href="collink.html#c">-cmt</a> <a href="collink.html#d">-dpp</a>
+ <a href="collink.html#p1">ProPhoto.icm</a> <a
+ href="collink.html#p2">RGBDestinationProfile.icm</a> <a
+ href="collink.html#p3">Source2Destination.icm</a><br>

+ <a href="cctiff.html">cctiff</a> <a href="cctiff.html#p1">Source2Destination.icm</a>
+ <a href="cctiff.html#p3">image.tif</a> <a href="cctiff.html#p4">printfile.tif</a><br>
+ <br>
+ The printfile.tif is then send to the printer without color
+ management, (i.e. in the same way the printer characterization test
+ chart was printed), since it is in the printers native colorspace.<br>
+ <br>
+ You can adjust how conservatively the image gamut is preserved using
+ the tiffgamut -f parameter. Omitting it or using a larger value (up
+ to 100) preserves the color gradations of even the lesser used
+ colors, at the cost of compressing the gamut more.<br>
+ Using a smaller value will preserve the saturation of the most
+ popular colors, at the cost of not preserving the color gradations
+ of less popular colors.<br>
+ <br>
+ You can create a gamut that covers a set of source images by
+ providing more than one image file name to tiffgamut. This may be
+ more efficient for a group of related images, and ensures that
+ colors are transformed in exactly the same way for all of the
+ images.<br>
+ <br>
+ An alternative generating a gamut for a specific set of images, is
+ to use a general smaller gamut definition (i.e. the sRGB profile),
+ or a gamut that represents the typical range of colors you wish to
+ preserve.<br>
+ <br>
+ The arguments to collink should be appropriate for the output device
+ type - see the collink examples in the above section.<br>

- <br>
- <b>3) Choice of where to apply display per channel calibration
- curves</b><br>
- <br>
- If calibration curves are going to be used, then it needs to be
- decided where they will be applied in the video processing chain.
- There are two options:<br>
- <br>
- <b>a)</b> Install the calibration curves in the playback system. On
- a PC the display, this can be done by loading the calibration curves
- into the Video Card temporarily using "dispwin calibration.cal", or
- installing the ICC profile into the system persistently using
- something like "<a href="dispwin.html#I">dispwin -I profile.icm</a>",<br>
- or when using MadVR 0.86.9 or latter by creating a 3dLut with
- appended calibration curves using <a href="collink#H">-H
- display.cal</a>.<br>
- <br>
- <b>b)</b> The calibration can be incorporated into the Device
- Link/3dLUT by providing it to collink as the <a
- href="collink.html#a">-a display.cal</a>. This is the only option
- if the video display path does not have some separate facility to
- handle calibration curves. Note that if the playback system has
- graphic card VideoLUTs then they will have to be set to a defined
- consistent state such as linear. When using MadVR 0.86.9 or latter
- this will be done automatically since the -a option will append a
- linear set of calibration curves to the 3dLut.<br>
- <br>
- The choice is dictated by a number of considerations:<br>
- <ul>
- <li>Does the video playback path have a facility for installing
- the calibration curves ? If playing back system is a PC, then
- typically the Graphics Card supports 1D VideoLUTs, thereby
- making a) a possible choice.<br>
- </li>
- <li>Does the video playback <u>always</u> play back through the
- Video Card VideoLUTs ? Some systems do not apply VIdeoLUTs to
- things like overlay plane rendering. If not, then you need to
- choose b), but also make sure that if it does use the Video Card
- VideoLUTs in some situations, that they are set to linear (ie.
- dispcal -c). One way of determining when the VideoLUTs get used
- or not is to load a distinct calibration such as "strange.cal"
- provided in the <b>ref</b> folder, and check visually if it is
- affecting the video or not, ie. "dispcal strange.cal". Note that
- using MadVR 0.86.9 or latter in combination with a 3dLut with
- appended calibration curves will apply the calibration even with
- overlay plane rendering.<br>
- </li>
- <li>Do you want/need other applications to share the calibration
- curves or profile or not ? If you do, then it is desirable to
- choose a).</li>
- <li>Quality considerations. VideoLUTs may or may not be of greater
- depth than the standard 8 bit per color component frame buffer.
- If they are, and the video path passes that extra depth through
- to the display, and the display is capable of using that extra
- depth, then a) may be a desirable choice from a quality point of
- view. You can get some idea whether this is the case by running
- "dispcal -R". If the VideoLUT depth is not better than 8 bits,
- then it may be more desirable to choose b), since renders like
- MadVR can use dithering to give better than 8 bits precision in
- the video playback.<br>
- </li>
- </ul>
- <h5>4) Output device calibration and profiling.</h5>
- Output device profiling should basically follow the guide above in <a
- href="#PM1b">Adjusting and Calibrating a displays</a> and <a
- href="#PM1">Profiling Displays</a>. The assumption is that either
- you are calibrating/profiling your computer display for video, or
- your TV is connected to the computer you are creating
- calibrations/profiles on, and that the connection between the PC and
- TV display is such that full range RGB signals are being used, or
- that the Video card has automatically or manually been configured to
- scale full range RGB values to Video levels for the TV. If the
- latter is not possible, then use the -E options on dispcal and
- dispread. (See <b>Signal encoding</b> bellow for more details on
- this). It may also improve the accuracy of the display profile if
- you use the <a href="dispread.html#Z">dispread -Z</a> option to
- quantize the test values to the precision of the display
- system.&nbsp; Don't use the -E options on dispcal and dispread, nor
- the -Z option on dispread if you are using MadVR to display test
- patches using the "-d madvr" option.<br>
- <br>
- Once the profile has been created, it is possible to then use the
- resulting Device Link/3DLut with signal encoding other than full
- range or Video level RGB. <br>
- <h5>5) Target colorspace<br>
- </h5>
- In practical terms, there are five common Video and Digital Cinema
- encoding colorspaces. <br>
- <br>
- For Standard Definition:<br>
- <br>
- &nbsp;&nbsp;&nbsp; EBU 3213 or "PAL 576i" primaries.<br>
- <br>
- &nbsp;&nbsp;&nbsp; SMPTE RP 145 or "NTSC 480i" primaries.<br>
- <br>
- For High Definition:<br>
- <br>
- &nbsp;&nbsp;&nbsp; Rec 709 primaries.<br>
- <br>
- For Ultra High Defintion<br>
- <br>
- &nbsp;&nbsp;&nbsp; Rec 2020 primaries.<br>
- <br>
- For Digital Cinema<br>
- <br>
- &nbsp;&nbsp;&nbsp; SMPTE-431-2&nbsp; or "DCI-P3"<br>
- <br>
- PAL and NTSC have historically had poorly specified transfer curve
- encodings, and the Rec 709 HDTV encoding curve is the modern <a
- href="http://www.poynton.com/notes/DVAI/DVAI_TOC_full.html#23">recommendation</a>,
- but the overall interpretation of Video sources may in fact be
- partly determined by the expected standard Video display device
- characteristics (see <b>Viewing conditions adjustment and gamut
- mapping</b> below for more details).<br>
- <br>
- To enable targeting these colorspaces, ArgyllCMS provides 5 ICC
- profiles in the ref directory to use as source
- colorspaces:&nbsp;&nbsp;&nbsp; <br>
- <br>
- &nbsp;&nbsp;&nbsp; EBU3213_PAL.icm<br>
- <br>
- &nbsp;&nbsp;&nbsp; SMPTE_RP145_NTSC.icm<br>
- <br>
- &nbsp;&nbsp;&nbsp; Rec709.icm<br>
- <br>
- &nbsp;&nbsp;&nbsp; Rec2020.icm<br>
- <br>
- &nbsp;&nbsp;&nbsp; SMPTE431_P3.icm<br>
- <h5>6) Signal encoding</h5>
- Typical PC display output uses full range RGB signals (0 .. 255 in 8
- bit parlance), while typical Video encoding allows some head &amp;
- footroom for overshoot and sync of digitized analog signals, and
- typically uses a 16..235 range in 8 bits. In many cases Video is
- encoded as luma and color difference signals YCbCr (loosely known as
- YUV as well), and this also uses a restricted range 16..235 for Y,
- and 16..240 for Cb and Cr in 8 bit encoding. The extended gamut
- xvYCC encoding uses 16..235 for Y, and 1..254 for Cb and Cr.<br>
- <br>
- The signal encoding comes into play in two situations: 1)
- Calibrating and profiling the display, and 2) Using the resulting
- Device Link/3DLut.<br>
- The encoding may need to be different in these two situations,
- either because different video source devices are being used for
- calibration/profiling and for video playback, or because the video
- playback system uses the Device Link/3DLut at a point in its
- processing pipeline that requires a specific encoding.<br>
- <br>
- For calibration &amp; profiling, the display will be driven by a
- computer system so that dispcal and dispread can be used. By default
- these programs expect to output full range RGB signals, and it is
- assumed that either the display accepts full range signals, or that
- the graphics card or connection path has been setup to convert the
- full range values into Video range signals automatically or
- manually. If this is not the case, then both dispcal and dispread
- have a -E option that will modify them to output Video range RGB
- values.<br>
- <br>
- If MadVR is the target of the calibration and profiling, then there
- is an option to use it to display the calibration and profiling test
- patches (<b>-d madvr</b>). In this case, MadVR should be configured
- appropriately for full range or Video range encoding, and the -E
- flag should <u>not</u> be used with dispcal or dispread, since
- MadVR will be taking care of such conversions.<br>
- <br>
- If a calibration file was created using dispcal -E, then using it in
- dispread will automatically trigger Video level RGB signals during
- profiling. Any time such a Video level calibration is loaded into
- the Graphics card VideoLUTs using dispwin, or the calibration curve
- is converted to a 'vcgt' tag in a profile, the curve will also
- convert full range RGB to Video range RGB. This should be kept in
- mind so that if video playback is being performed with the
- calibration curves installed in the Graphics card VideoLUTs, that
- full range is converted only once to Video range (ie. In this
- situation MadVR output should be set to full range if being played
- back through the calibration curves in hardware, but only if dispcal
- -E has been used). On the other hand, if the calibration curves are
- incorporated into the DeviceLink/3dLUT, then the conversion to Video
- levels has to be done somewhere else in the pipeline, such as using
- MadVR video level output, or by the graphics card, etc.<br>
- <br>
- When creating the Device Link/3dLut, it is often necessary to
- specify one of the video encodings so that it fits in to the
- processing pipeline correctly. For instance the eeColor needs to
- have input and output encoding that suits the HDMI signals passing
- through it, typically Video Range RGB. MadVR needs Video Level RGB
- to match the values being passed through the 3dLut at that point.<br>
- <br>
- There are several version of YCbCr encoding supported as well, even
- though neither the eeColor nor the current version of MadVR need or
- can use them at present.<br>
- <h5>7) Black point mapping</h5>
- <p>Video encoding assumes that the black displayed on a device is a
- perfect black (zero light). No real device has a perfect black,
- and if a colorimetric intent is used then certain image values
- near black will get clipped to the display black point, loosing
- shadow detail. To avoid this, some sort of black point mapping is
- usually desirable. There are two mechanisms available in collink:
- a) Custom EOTF with input and/or output black point mapping, or b)
- using one of the smart gamut mapping intents that does black point
- mapping (e.g. la, p, pa, ms or s).<br>
- </p>
- <h5>8) Viewing conditions adjustment and gamut mapping</h5>
- <p> </p>
- <p>In historical TV systems, there is a viewing conditions
- adjustment being made between the bright studio conditions that TV
- is filmed in, and the typical dim viewing environment that people
- view it in. This is created by the difference between the encoding
- response curve gamma of about 2.0, and a typical CRT response
- curve gamma of 2.4. <br>
- </p>
- <p>In theory Rec709 defines the video encoding, but it seems in
- practice that much video material is adjusted to look as intended
- when displayed on a reference monitor having a display gamma of
- somewhere between 2.2 and 2.4, viewed in a dim viewing
- environment. The modern standard covering the display EOTF
- (Electro-Optical Transfer Curve) is <a
- href="http://www.itu.int/rec/R-REC-BT.1886-0-201103-I">BT.1886</a>,
- which defines a pure power 2.4 curve with an input offset and
- scale applied to account for the black point offset while
- retaining dark shadow tonality. So another means of making the
- viewing adjustment is to use the BT.1886-like EOTF for Rec709
- encoded material. Collink supports this using the <a
- href="collink.html#I">-I b</a>, and allows some control over the
- degree of viewing conditions adjustment by overriding the BT.1886
- gamma&nbsp; using the <a href="collink.html#Ib">-I b:g.g</a>
- parameter. This is the <b>recommended</b> approach to start with,
- since it gives good results with a single parameter.<br>
- </p>
- <p>The addition of a second optional parameter <a
- href="collink.html#Ib">-I b:p.p:g.g</a>
- allows control over the degree of black point offset accounted for
- as an output offset, as opposed to input offset Once the effective
- gamma value has been chosen to suite the viewing conditions and
- set the overall contrast for mid greys, increasing the proportion
- of black offset accounted for in the output of the curve is a way
- of reducing the deep shadow detail, if it is being overly
- emphasized. </p>
- <p> An alternate approach to making this adjustment is to take
- advantage of the viewing conditions adjustment using the CIECAM02
- model available in collink. Some control over the degree of
- viewing conditions adjustment is possible by varying the viewing
- condition parameters. </p>
- <p>A third alternative is to combine the two approaches. The source
- is defined as Rec709 primaries with a BT.1886-like EOTF display in
- dim viewing conditions, and then CIECAM02 is used to adjust for
- the actual display viewing conditions. Once again, control over
- the degree of viewing conditions adjustment is possible by varying
- the viewing condition parameters<br>
- </p>
- <p><br>
- </p>
- <p><b>9) Correcting for any black point inaccuracy in the display
- profile</b><br>
- </p>
- <p>Some video display devices have particularly good black points,
- and any slight raising of the black due to innacuracies in the
- display profile near black can be objectionable. As well as using
- the <a href="targen.html#V">targen -V flag</a> to improve
- accuracy near black during profiling, if the display is known to
- be well behaved (ie. that it's darkest black is actually at RGB
- value 0,0,0), then the <a href="collink.html#b">collink -b</a>
- flag can be used, to force the source RGB 0,0,0 to map to the
- display 0,0,0.<br>
- </p>
- <h5>Putting it all together:</h5>
- In this example we choose to create a display calibration first
- using dispcal, and create a simple matrix profile as well:<br>
- <br>
- &nbsp; <tt>dispcal -v -o -qm -k0 -w 0.3127,0.3290 -gs -o TVmtx.icm
- TV</tt><br>
- <br>
- We are targeting a D65 white point (<tt>-w 0.3127,0.3290)</tt> and
- an sRGB response curve.<br>
- <br>
- If you are using the madTPG you would use:<br>
- <br>
- &nbsp; <tt>dispcal -v -d madvr -o -qm -k0 -w 0.3127,0.3290 -gs -o
- TVmtx.icm TV</tt><br>
- <br>
- Then we need to create a display patch test set. We can use the
- simple matrix to pre-condition the test patches, as this helps
- distribute them where they will be of most benefit. If have
- previously profiled your display, you should use that previous
- profile, or if you decided not to do a dispcal, then the Rec709.icm
- should be used as a substitute. Some per channel and a moderate
- number of full spread patches is used here - more will increase
- profiling accuracy, a smaller number will speed it up. Since the
- video or film material is typically viewed in a darkened viewing
- environment, and often uses a range of maximum brightnesses in
- different scenes, the device behavior in the dark regions of its
- response are often of great importance, and using the <a
- href="targen.html#V">targen -V</a> parameter can help improve the
- accuracy in this region at the expense of slightly lower accuracy in
- lighter regions.<br>
- <br>
- &nbsp; <tt>targen -v -d3 -s30 -g100 -f1000 -cTVmtx.icm -V1.8 TV</tt><br>
- <br>
- The display can then be measured:<br>
- <br>
- &nbsp; <tt>dispread -v -k -Z8 TV.cal TV</tt><br>
- <br>
- or using madTPG:<br>
- <br>
- &nbsp;dispread -v -d madvr -K TV.cal TV<br>
- <br>
- and then a cLUT type ICC profile created. Since we will be using
- collink smart linking, we minimize the B2A table size. We use the
- default colprof -V parameter carried through from targen:<br>
- <br>
- &nbsp; <tt>colprof -v -qh -bl TV</tt><br>
- <br>
- Make sure you check the delta E report at the end of the profile
- creation, to see if the sample data and profile is behaving
- reasonably. Depending on the type of device, and the consistency of
- the readings, average errors of 5 or less, and maximum errors of 15
- or less would normally be expected. If errors are grossly higher
- than this, then this is an indication that something is seriously
- wrong with the device measurement, or profile creation.<br>
- <br>
- If you would like to use the display ICC profile for general color
- managed applications, then you would compute a more complete
- profile:<br>
- <br>
- &nbsp; <tt>colprof -v -qh TV</tt><br>
- <br>
- The recommended approach then is to create a Device Link that uses a
- BT.1886 black point and viewing conditions adjustment, say one of
- the following:<br>
- <br>
- <tt>&nbsp; collink -v -Ib:2.4 -b -G -ir Rec709.icm TV.icm
- HD.icm&nbsp;&nbsp; # dark conditions</tt><tt><br>
- </tt><tt> &nbsp; collink -v -Ib&nbsp;&nbsp;&nbsp;&nbsp; -b -G -ir
- Rec709.icm TV.icm HD.icm&nbsp;&nbsp; # dim conditions - good
- default</tt><tt><br>
- </tt><tt> &nbsp; collink -v -Ib:2.1 -b -G -ir Rec709.icm TV.icm
- HD.icm&nbsp;&nbsp; # mid to dim conditions</tt><tt><br>
- </tt><tt> &nbsp; collink -v -Ib:2.0 -b -G -ir Rec709.icm TV.icm
- HD.icm&nbsp;&nbsp; # mid to light conditions</tt><br>
- <br>
- or you could do it using pure CIECAM02 adjustment and a black point
- mapping:<br>
- <br>
- <tt>&nbsp; collink -v -ctv -dmd -da:1 -G -ila Rec709.icm TV.icm
- HD.icm&nbsp; # very dark conditions</tt><tt><br>
- </tt><tt> &nbsp; collink -v -ctv -dmd -da:3 -G -ila Rec709.icm
- TV.icm HD.icm&nbsp; # dim conditions</tt><tt><br>
- </tt><tt> &nbsp; collink -v -ctv -dmd -da:7 -G -ila Rec709.icm
- TV.icm HD.icm&nbsp; # mid to dim conditions - good default</tt><tt><br>
- </tt><tt> &nbsp; collink -v -ctv -dmd -da:15 -G -ila Rec709.icm
- TV.icm HD.icm # mid conditions</tt><br>
- <br>
- or using both to model a reference video display system that is
- adapted to your viewing conditions:<br>
- <tt><br>
- </tt><tt> &nbsp; collink -v -Ib -c md -dmd -da:5&nbsp; -G -ila
- Rec709.icm TV.icm HD.icm # very dark conditions</tt><tt><br>
- </tt><tt> &nbsp; collink -v -Ib -c md -dmd -da:10 -G -ila Rec709.icm
- TV.icm HD.icm&nbsp; # dim conditions</tt><tt><br>
- </tt><tt> &nbsp; collink -v -Ib -c md -dmd -da:18 -G -ila Rec709.icm
- TV.icm HD.icm&nbsp; # mid to dark conditions</tt><tt><br>
- </tt><tt> &nbsp; collink -v -Ib -c md -dmd -da:30 -G -ila Rec709.icm
- TV.icm HD.icm&nbsp;&nbsp; # mid to dark conditions</tt><br>
- <br>
- None of the above examples incorporate the calibration curves, so it
- is assumed that the calibration curves would be installed so that

- <br>
- If the video path needs Video Level RGB encoding but does not

- <br>
- Below are specific recommendation for the eeColor and MadVR that

- <br>
- For faster exploration of different collink option, you could omit

- <br>
- You can also increase the precision of the device profile by

- <br>
- Alternatives to relative colorimetric rendering ("-i r") or

- for some more details.<br>
- <br>
- Where the eeColor is connected from a Video source using HDMI, it

- <br>
- <b>MadVR</b><br>
- <br>
- MadVR 0.86.9 or latter has a number of features to support accurate
- profiling and calibration, and is the recommended version to
- use.&nbsp; It converts from the media colorspace to the 3dLut input
- space automatically with the type of source being played, but has
- configuration for to 5 3dLuts, each one optimized for a particular

- <br>
- If you are just building one 3dLut then Rec709 source is a good one

+
+
+ of where to apply display per channel calibration curves.</b></li>
+ <li>Choose one of the Absolute Colorimetric intents in collink
+ (ie. -i aw). This greatly reduces flexibility, and may not be
+ quite as accurate as an explicit calibration.</li>
+ </ul>
+ If an explicit calibration is used, then it is a good idea to add
+ some test points down the neutral axis when profiling (targen <a
+ href="targen.html#g">-g parameter</a>). <br>
+ <br>
+ <b>3) Choice of where to apply display per channel calibration
+ curves</b><br>
+ <br>
+ If calibration curves are going to be used, then it needs to be
+ decided where they will be applied in the video processing chain.
+ There are two options:<br>
+ <br>
+ <b>a)</b> Install the calibration curves in the playback system. On
+ a PC the display, this can be done by loading the calibration curves
+ into the Video Card temporarily using "dispwin calibration.cal", or
+ installing the ICC profile into the system persistently using
+ something like "<a href="dispwin.html#I">dispwin -I profile.icm</a>",<br>
+ or when using MadVR 0.86.9 or latter by creating a 3dLut with
+ appended calibration curves using <a href="collink#H">-H
+ display.cal</a>.<br>
+ <br>
+ <b>b)</b> The calibration can be incorporated into the Device
+ Link/3dLUT by providing it to collink as the <a
+ href="collink.html#a">-a display.cal</a>. This is the only option
+ if the video display path does not have some separate facility to
+ handle calibration curves. Note that if the playback system has
+ graphic card VideoLUTs then they will have to be set to a defined
+ consistent state such as linear. When using MadVR 0.86.9 or latter
+ this will be done automatically since the -a option will append a
+ linear set of calibration curves to the 3dLut.<br>
+ <br>
+ The choice is dictated by a number of considerations:<br>
+ <ul>
+ <li>Does the video playback path have a facility for installing
+ the calibration curves ? If playing back system is a PC, then
+ typically the Graphics Card supports 1D VideoLUTs, thereby
+ making a) a possible choice.<br>
+ </li>
+ <li>Does the video playback <u>always</u> play back through the
+ Video Card VideoLUTs ? Some systems do not apply VIdeoLUTs to
+ things like overlay plane rendering. If not, then you need to
+ choose b), but also make sure that if it does use the Video Card
+ VideoLUTs in some situations, that they are set to linear (ie.
+ dispcal -c). One way of determining when the VideoLUTs get used
+ or not is to load a distinct calibration such as "strange.cal"
+ provided in the <b>ref</b> folder, and check visually if it is
+ affecting the video or not, ie. "dispcal strange.cal". Note that
+ using MadVR 0.86.9 or latter in combination with a 3dLut with
+ appended calibration curves will apply the calibration even with
+ overlay plane rendering.<br>
+ </li>
+ <li>Do you want/need other applications to share the calibration
+ curves or profile or not ? If you do, then it is desirable to
+ choose a).</li>
+ <li>Quality considerations. VideoLUTs may or may not be of greater
+ depth than the standard 8 bit per color component frame buffer.
+ If they are, and the video path passes that extra depth through
+ to the display, and the display is capable of using that extra
+ depth, then a) may be a desirable choice from a quality point of
+ view. You can get some idea whether this is the case by running
+ "dispcal -R". If the VideoLUT depth is not better than 8 bits,
+ then it may be more desirable to choose b), since renders like
+ MadVR can use dithering to give better than 8 bits precision in
+ the video playback.<br>
+ </li>
+ </ul>
+ <h5>4) Output device calibration and profiling.</h5>
+ Output device profiling should basically follow the guide above in <a
+ href="#PM1b">Adjusting and Calibrating a displays</a> and <a
+ href="#PM1">Profiling Displays</a>. The assumption is that either
+ you are calibrating/profiling your computer display for video, or
+ your TV is connected to the computer you are creating
+ calibrations/profiles on, and that the connection between the PC and
+ TV display is such that full range RGB signals are being used, or
+ that the Video card has automatically or manually been configured to
+ scale full range RGB values to Video levels for the TV. If the
+ latter is not possible, then use the -E options on dispcal and
+ dispread. (See <b>Signal encoding</b> bellow for more details on
+ this). It may also improve the accuracy of the display profile if
+ you use the <a href="dispread.html#Z">dispread -Z</a> option to
+ quantize the test values to the precision of the display
+ system.&nbsp; Don't use the -E options on dispcal and dispread, nor
+ the -Z option on dispread if you are using MadVR to display test
+ patches using the "-d madvr" option.<br>
+ <br>
+ Once the profile has been created, it is possible to then use the
+ resulting Device Link/3DLut with signal encoding other than full
+ range or Video level RGB. <br>
+ <h5>5) Target colorspace<br>
+ </h5>
+ In practical terms, there are five common Video and Digital Cinema
+ encoding colorspaces. <br>
+ <br>
+ For Standard Definition:<br>
+ <br>
+ &nbsp;&nbsp;&nbsp; EBU 3213 or "PAL 576i" primaries.<br>
+ <br>
+ &nbsp;&nbsp;&nbsp; SMPTE RP 145 or "NTSC 480i" primaries.<br>
+ <br>
+ For High Definition:<br>
+ <br>
+ &nbsp;&nbsp;&nbsp; Rec 709 primaries.<br>
+ <br>
+ For Ultra High Defintion<br>
+ <br>
+ &nbsp;&nbsp;&nbsp; Rec 2020 primaries.<br>
+ <br>
+ For Digital Cinema<br>
+ <br>
+ &nbsp;&nbsp;&nbsp; SMPTE-431-2&nbsp; or "DCI-P3"<br>
+ <br>
+ PAL and NTSC have historically had poorly specified transfer curve
+ encodings, and the Rec 709 HDTV encoding curve is the modern <a
+ href="http://www.poynton.com/notes/DVAI/DVAI_TOC_full.html#23">recommendation</a>,
+ but the overall interpretation of Video sources may in fact be
+ partly determined by the expected standard Video display device
+ characteristics (see <b>Viewing conditions adjustment and gamut
+ mapping</b> below for more details).<br>
+ <br>
+ To enable targeting these colorspaces, ArgyllCMS provides 5 ICC
+ profiles in the ref directory to use as source
+ colorspaces:&nbsp;&nbsp;&nbsp; <br>
+ <br>
+ &nbsp;&nbsp;&nbsp; EBU3213_PAL.icm<br>
+ <br>
+ &nbsp;&nbsp;&nbsp; SMPTE_RP145_NTSC.icm<br>
+ <br>
+ &nbsp;&nbsp;&nbsp; Rec709.icm<br>
+ <br>
+ &nbsp;&nbsp;&nbsp; Rec2020.icm<br>
+ <br>
+ &nbsp;&nbsp;&nbsp; SMPTE431_P3.icm<br>
+ <h5>6) Signal encoding</h5>
+ Typical PC display output uses full range RGB signals (0 .. 255 in 8
+ bit parlance), while typical Video encoding allows some head &amp;
+ footroom for overshoot and sync of digitized analog signals, and
+ typically uses a 16..235 range in 8 bits. In many cases Video is
+ encoded as luma and color difference signals YCbCr (loosely known as
+ YUV as well), and this also uses a restricted range 16..235 for Y,
+ and 16..240 for Cb and Cr in 8 bit encoding. The extended gamut
+ xvYCC encoding uses 16..235 for Y, and 1..254 for Cb and Cr.<br>
+ <br>
+ The signal encoding comes into play in two situations: 1)
+ Calibrating and profiling the display, and 2) Using the resulting
+ Device Link/3DLut.<br>
+ The encoding may need to be different in these two situations,
+ either because different video source devices are being used for
+ calibration/profiling and for video playback, or because the video
+ playback system uses the Device Link/3DLut at a point in its
+ processing pipeline that requires a specific encoding.<br>
+ <br>
+ For calibration &amp; profiling, the display will be driven by a
+ computer system so that dispcal and dispread can be used. By default
+ these programs expect to output full range RGB signals, and it is
+ assumed that either the display accepts full range signals, or that
+ the graphics card or connection path has been setup to convert the
+ full range values into Video range signals automatically or
+ manually. If this is not the case, then both dispcal and dispread
+ have a -E option that will modify them to output Video range RGB
+ values.<br>
+ <br>
+ If MadVR is the target of the calibration and profiling, then there
+ is an option to use it to display the calibration and profiling test
+ patches (<b>-d madvr</b>). In this case, MadVR should be configured
+ appropriately for full range or Video range encoding, and the -E
+ flag should <u>not</u> be used with dispcal or dispread, since
+ MadVR will be taking care of such conversions.<br>
+ <br>
+ If a calibration file was created using dispcal -E, then using it in
+ dispread will automatically trigger Video level RGB signals during
+ profiling. Any time such a Video level calibration is loaded into
+ the Graphics card VideoLUTs using dispwin, or the calibration curve
+ is converted to a 'vcgt' tag in a profile, the curve will also
+ convert full range RGB to Video range RGB. This should be kept in
+ mind so that if video playback is being performed with the
+ calibration curves installed in the Graphics card VideoLUTs, that
+ full range is converted only once to Video range (ie. In this
+ situation MadVR output should be set to full range if being played
+ back through the calibration curves in hardware, but only if dispcal
+ -E has been used). On the other hand, if the calibration curves are
+ incorporated into the DeviceLink/3dLUT, then the conversion to Video
+ levels has to be done somewhere else in the pipeline, such as using
+ MadVR video level output, or by the graphics card, etc.<br>
+ <br>
+ When creating the Device Link/3dLut, it is often necessary to
+ specify one of the video encodings so that it fits in to the
+ processing pipeline correctly. For instance the eeColor needs to
+ have input and output encoding that suits the HDMI signals passing
+ through it, typically Video Range RGB. MadVR needs Video Level RGB
+ to match the values being passed through the 3dLut at that point.<br>
+ <br>
+ There are several version of YCbCr encoding supported as well, even
+ though neither the eeColor nor the current version of MadVR need or
+ can use them at present.<br>
+ <h5>7) Black point mapping</h5>
+ <p>Video encoding assumes that the black displayed on a device is a
+ perfect black (zero light). No real device has a perfect black,
+ and if a colorimetric intent is used then certain image values
+ near black will get clipped to the display black point, loosing
+ shadow detail. To avoid this, some sort of black point mapping is
+ usually desirable. There are two mechanisms available in collink:
+ a) Custom EOTF with input and/or output black point mapping, or b)
+ using one of the smart gamut mapping intents that does black point
+ mapping (e.g. la, p, pa, ms or s).<br>
+ </p>
+ <h5>8) Viewing conditions adjustment and gamut mapping</h5>
+ <p> </p>
+ <p>In historical TV systems, there is a viewing conditions
+ adjustment being made between the bright studio conditions that TV
+ is filmed in, and the typical dim viewing environment that people
+ view it in. This is created by the difference between the encoding
+ response curve gamma of about 2.0, and a typical CRT response
+ curve gamma of 2.4. <br>
+ </p>
+ <p>In theory Rec709 defines the video encoding, but it seems in
+ practice that much video material is adjusted to look as intended
+ when displayed on a reference monitor having a display gamma of
+ somewhere between 2.2 and 2.4, viewed in a dim viewing
+ environment. The modern standard covering the display EOTF
+ (Electro-Optical Transfer Curve) is <a
+ href="http://www.itu.int/rec/R-REC-BT.1886-0-201103-I">BT.1886</a>,
+ which defines a pure power 2.4 curve with an input offset and
+ scale applied to account for the black point offset while
+ retaining dark shadow tonality. So another means of making the
+ viewing adjustment is to use the BT.1886-like EOTF for Rec709
+ encoded material. Collink supports this using the <a
+ href="collink.html#I">-I b</a>, and allows some control over the
+ degree of viewing conditions adjustment by overriding the BT.1886
+ gamma&nbsp; using the <a href="collink.html#Ib">-I b:g.g</a>
+ parameter. This is the <b>recommended</b> approach to start with,
+ since it gives good results with a single parameter.<br>
+ </p>
+ <p>The addition of a second optional parameter <a
+ href="collink.html#Ib">-I b:p.p:g.g</a> allows control over the
+ degree of black point offset accounted for as an output offset, as
+ opposed to input offset Once the effective gamma value has been
+ chosen to suite the viewing conditions and set the overall
+ contrast for mid greys, increasing the proportion of black offset
+ accounted for in the output of the curve is a way of reducing the
+ deep shadow detail, if it is being overly emphasized. </p>
+ <p> An alternate approach to making this adjustment is to take
+ advantage of the viewing conditions adjustment using the CIECAM02
+ model available in collink. Some control over the degree of
+ viewing conditions adjustment is possible by varying the viewing
+ condition parameters. </p>
+ <p>A third alternative is to combine the two approaches. The source
+ is defined as Rec709 primaries with a BT.1886-like EOTF display in
+ dim viewing conditions, and then CIECAM02 is used to adjust for
+ the actual display viewing conditions. Once again, control over
+ the degree of viewing conditions adjustment is possible by varying
+ the viewing condition parameters<br>
+ </p>
+ <p><br>
+ </p>
+ <p><b>9) Correcting for any black point inaccuracy in the display
+ profile</b><br>
+ </p>
+ <p>Some video display devices have particularly good black points,
+ and any slight raising of the black due to innacuracies in the
+ display profile near black can be objectionable. As well as using
+ the <a href="targen.html#V">targen -V flag</a> to improve
+ accuracy near black during profiling, if the display is known to
+ be well behaved (ie. that it's darkest black is actually at RGB
+ value 0,0,0), then the <a href="collink.html#b">collink -b</a>
+ flag can be used, to force the source RGB 0,0,0 to map to the
+ display 0,0,0.<br>
+ </p>
+ <h5>Putting it all together:</h5>
+ In this example we choose to create a display calibration first
+ using dispcal, and create a simple matrix profile as well:<br>
+ <br>
+ &nbsp; <tt>dispcal -v -o -qm -k0 -w 0.3127,0.3290 -gs -o TVmtx.icm
+ TV</tt><br>
+ <br>
+ We are targeting a D65 white point (<tt>-w 0.3127,0.3290)</tt> and
+ an sRGB response curve.<br>
+ <br>
+ If you are using the madTPG you would use:<br>
+ <br>
+ &nbsp; <tt>dispcal -v -d madvr -o -qm -k0 -w 0.3127,0.3290 -gs -o
+ TVmtx.icm TV</tt><br>
+ <br>
+ Then we need to create a display patch test set. We can use the
+ simple matrix to pre-condition the test patches, as this helps
+ distribute them where they will be of most benefit. If have
+ previously profiled your display, you should use that previous
+ profile, or if you decided not to do a dispcal, then the Rec709.icm
+ should be used as a substitute. Some per channel and a moderate
+ number of full spread patches is used here - more will increase
+ profiling accuracy, a smaller number will speed it up. Since the
+ video or film material is typically viewed in a darkened viewing
+ environment, and often uses a range of maximum brightnesses in
+ different scenes, the device behavior in the dark regions of its
+ response are often of great importance, and using the <a
+ href="targen.html#V">targen -V</a> parameter can help improve the
+ accuracy in this region at the expense of slightly lower accuracy in
+ lighter regions.<br>
+ <br>
+ &nbsp; <tt>targen -v -d3 -s30 -g100 -f1000 -cTVmtx.icm -V1.8 TV</tt><br>
+ <br>
+ The display can then be measured:<br>
+ <br>
+ &nbsp; <tt>dispread -v -k -Z8 TV.cal TV</tt><br>
+ <br>
+ or using madTPG:<br>
+ <br>
+ &nbsp;dispread -v -d madvr -K TV.cal TV<br>
+ <br>
+ and then a cLUT type ICC profile created. Since we will be using
+ collink smart linking, we minimize the B2A table size. We use the
+ default colprof -V parameter carried through from targen:<br>
+ <br>
+ &nbsp; <tt>colprof -v -qh -bl TV</tt><br>
+ <br>
+ Make sure you check the delta E report at the end of the profile
+ creation, to see if the sample data and profile is behaving
+ reasonably. Depending on the type of device, and the consistency of
+ the readings, average errors of 5 or less, and maximum errors of 15
+ or less would normally be expected. If errors are grossly higher
+ than this, then this is an indication that something is seriously
+ wrong with the device measurement, or profile creation.<br>
+ <br>
+ If you would like to use the display ICC profile for general color
+ managed applications, then you would compute a more complete
+ profile:<br>
+ <br>
+ &nbsp; <tt>colprof -v -qh TV</tt><br>
+ <br>
+ The recommended approach then is to create a Device Link that uses a
+ BT.1886 black point and viewing conditions adjustment, say one of
+ the following:<br>
+ <br>
+ <tt>&nbsp; collink -v -Ib:2.4 -b -G -ir Rec709.icm TV.icm
+ HD.icm&nbsp;&nbsp; # dark conditions</tt><tt><br>
+ </tt><tt> &nbsp; collink -v -Ib&nbsp;&nbsp;&nbsp;&nbsp; -b -G -ir
+ Rec709.icm TV.icm HD.icm&nbsp;&nbsp; # dim conditions - good
+ default</tt><tt><br>
+ </tt><tt> &nbsp; collink -v -Ib:2.1 -b -G -ir Rec709.icm TV.icm
+ HD.icm&nbsp;&nbsp; # mid to dim conditions</tt><tt><br>
+ </tt><tt> &nbsp; collink -v -Ib:2.0 -b -G -ir Rec709.icm TV.icm
+ HD.icm&nbsp;&nbsp; # mid to light conditions</tt><br>
+ <br>
+ or you could do it using pure CIECAM02 adjustment and a black point
+ mapping:<br>
+ <br>
+ <tt>&nbsp; collink -v -ctv -dmd -da:1 -G -ila Rec709.icm TV.icm
+ HD.icm&nbsp; # very dark conditions</tt><tt><br>
+ </tt><tt> &nbsp; collink -v -ctv -dmd -da:3 -G -ila Rec709.icm
+ TV.icm HD.icm&nbsp; # dim conditions</tt><tt><br>
+ </tt><tt> &nbsp; collink -v -ctv -dmd -da:7 -G -ila Rec709.icm
+ TV.icm HD.icm&nbsp; # mid to dim conditions - good default</tt><tt><br>
+ </tt><tt> &nbsp; collink -v -ctv -dmd -da:15 -G -ila Rec709.icm
+ TV.icm HD.icm # mid conditions</tt><br>
+ <br>
+ or using both to model a reference video display system that is
+ adapted to your viewing conditions:<br>
+ <tt><br>
+ </tt><tt> &nbsp; collink -v -Ib -c md -dmd -da:5&nbsp; -G -ila
+ Rec709.icm TV.icm HD.icm # very dark conditions</tt><tt><br>
+ </tt><tt> &nbsp; collink -v -Ib -c md -dmd -da:10 -G -ila Rec709.icm
+ TV.icm HD.icm&nbsp; # dim conditions</tt><tt><br>
+ </tt><tt> &nbsp; collink -v -Ib -c md -dmd -da:18 -G -ila Rec709.icm
+ TV.icm HD.icm&nbsp; # mid to dark conditions</tt><tt><br>
+ </tt><tt> &nbsp; collink -v -Ib -c md -dmd -da:30 -G -ila Rec709.icm
+ TV.icm HD.icm&nbsp;&nbsp; # mid to dark conditions</tt><br>
+ <br>
+ None of the above examples incorporate the calibration curves, so it
+ is assumed that the calibration curves would be installed so that
+ the Video Card applies calibration, ie:<br>
+ <br>
+ &nbsp;&nbsp;&nbsp; <tt>dispwin TV.cal</tt><br>
+ <br>
+ or the simple matrix profile installed:<br>
+ <br>
+ &nbsp;&nbsp;&nbsp; <tt>dispwin -I TVmtx.icm</tt><br>
+ <br>
+ or a the more complete display profile could be installed:<br>
+ <br>
+ &nbsp; dispwin -I TV.icm<br>
+ <br>
+ See also <a href="dispprofloc.html">here</a> for information on how
+ to make sure the calibration is loaded on each system start. If not,
+ then you will want to incorporate the calibration in the Device
+ Link/3dlut by using collink "-a TV.cal".<br>
+ <br>
+ If the video path needs Video Level RGB encoding but does not
+ provide a means to do this, then you will want to include the <b>-E</b>
+ flag in the dispcal and dispread command lines above.<br>
+ <br>
+ Below are specific recommendation for the eeColor and MadVR that
+ include the flags to create the .3dlut and encode the input and
+ output values appropriately, but only illustrate using the
+ recommended BT.1886 black point and viewing conditions adjustments,
+ rather than illustrating CIECAM02 etc. use.<br>
+ <br>
+ For faster exploration of different collink option, you could omit
+ the "colprof -bl" option, and use collink "-g" instead of "-G",
+ since this<br>
+ will greatly speed up collink. Once you are happy with the link
+ details, you can then generate a higher quality link/3dLut using
+ "collink -G ..".<br>
+ <br>
+ You can also increase the precision of the device profile by
+ increasing the number of test patches measured (ie. up to a few
+ thousand, depending on how long you are prepared to wait for the
+ measurement to complete, and how stable your display and instrument
+ are).<br>
+ <br>
+ Alternatives to relative colorimetric rendering ("-i r") or
+ luminance matched appearance ("-i la") used in the examples above
+ and below, are, perceptual ("-i p") which will ensure that the
+ source gamut is compressed rather than clipped by the display, or
+ even a saturation rendering ("-i ms"), which will expand the gamut
+ of the source to the full range of the output.<br>

+ Where the eeColor is connected from a Video source using HDMI, it

+ Rec709.icm TV.icm HD.icm </tt><br>
+ <br>
+ in this case just the HD.txt file needs installing on the eeColor,
+ but make sure that the original linear "first1*.txt files are
+ re-installed, or install the ones generated by collink, which will
+ be linear for -e t mode.<br>

+ <b>MadVR</b><br>
+ <br>
+ MadVR 0.86.9 or latter has a number of features to support accurate
+ profiling and calibration, and is the recommended version to
+ use.&nbsp; It converts from the media colorspace to the 3dLut input
+ space automatically with the type of source being played, but has
+ configuration for to 5 3dLuts, each one optimized for a particular
+ source color space. The advantage of building and installing several
+ 3dLuts is that unnecessary gamut clipping can be avoided.<br>
+ <br>
+ If you are just building one 3dLut then Rec709 source is a good one
+ to pick.<br>
+ <br>
+ If you want to share the VideoLUT calibration curves between your
+ normal desktop and MadVR, then it is recommended that you install
+ the display ICC profile and use the -H option:<br>

- <h3><a name="TV2"></a>Verifying Video Calibration</h3>
- <p>Often it is desirable to verify the results of a video
- calibration and profile, and the following gives an outline of how
- to use ArgyllCMS tools to do this. It is only possible to expect
- perfect verification if a colorimetric intent was used during
- linking - currently it's not possible to exactly verify a
- perceptual or CIECAM02 viewing condition adjusted link.<br>
- <br>
- </p>
- <p>The first step is to create a set of test points. This is
- essentially the same as creating a set of test points for the
- purposes of profiling, although it is best not to create exactly
- the same set, so as to explore the colorspace at different
- locatioins. For the purposes here, we'll actually create a regular
- grid test set, since this makes it easier to visualize the
- results, although a less regular set would probably be better for
- numerical evaluation:<br>
- </p>
- <p>&nbsp; targen -v -d3 -e1 -m6 -f0 -W verify<br>
- </p>
- <p>We make sure there is at least one white patch usin g -e1, a 20%
- increment grid using -m6, no full spread patches, and create an
- X3DOM 3d visualization of the point set using the -W flag. It is
- good to take a look at the verifyd.x3d.html file using a Web
- browser. You may want to create several test sets that look at
- particular aspects, ie. neutral axis response, pure colorant
- responses, etc.<br>
- </p>
- <p>Next we create a reference file by simulating the expected
- response of the perfect video display system. Assuming the collink
- options were "-et -Et -Ib -G -ir Rec709.icm TV.icm HD.icm" then we
- would:<tt><tt><br>
- </tt></tt></p>
- <p><tt><tt>&nbsp; copy verify.ti1 ref.ti1<br>
- &nbsp; fakeread -v -b -Z8 TV.icm Rec709.icm ref<br>
- </tt></tt></p>
- <p>You should adjust the parameters as necessary, so that the
- reference matches the link options. For instance, if your link
- options included "-I b:0.2:2.15" then the equivalent fakeread
- option "-b 0.2:2.15:TV.icm" should be used, etc.<br>
- </p>
- <hr size="2" width="20%">
- <p>A sanity check we can make at this point is to see what the
- expected result of the profiling &amp; calibration will be, by
- simulating the reproduction of this test set:<br>
- </p>
- <p><tt>&nbsp; copy verify.ti1 checkA.ti1</tt><tt><br>
- &nbsp; fakeread -v -et -Z8 -p HD.icm -Et TV.icm checkA<br>
- </tt></p>
- <p>If you used collink -a, then the calibration incorporated in the
- device link needs to be undone to match what the display profile
- expects:</p>
- <p><tt>&nbsp; fakeread -v -et -Z8 -p HD.icm -Et -K TV.cal TV.icm
- checkA</tt></p>
- <p><tt>and then you can verify:<br>
- </tt></p>
- <p><tt>&nbsp; colverify -v -n -w -x ref.ti3 checkA.ti3<br>
- </tt></p>
- <p>If you have targeted some other white point rather than video D65
- for the display, then use the -N flag instead of -n to align the
- white points. [ Note that there can be some small discrepancies in
- this case in some parts of the color space if a CIECAM02 linking
- intent was used, due to the slightly different chromatic
- adaptation algorithm it uses compared to the one used by verify to
- match the white points.]<tt><br>
- </tt></p>
- <p><tt>&nbsp; v</tt><tt>erify -v -N -w -x ref.ti3 checkA.ti3</tt><br>
- </p>
- <p>This will give a numerical report of the delta E's, and also
- generate an X3DOM plot of the errors in L*a*b* space. The
- important thing is to take a look at the checkA.x3d.html file, to
- see if gamut clipping is occurring - this is the case if the large
- error vectors are on the sides or top of the gamut. Note that the
- perfect cube device space values become a rather distorted cube
- like shape in the perceptual L*a*b* space. If the vectors are
- small in the bulk of the space, then this indicates that the link
- is likely to be doing the right thing in making the display
- emulate the video colorspace with a BT.1886 like black point
- adjustment. You could also check just the in gamut test points
- using:<br>
- </p>
- <p><tt>&nbsp; v</tt><tt>erify -v -N -w -x -L TV.icm ref.ti3
- checkA.ti3<br>
- <br>
- </tt></p>
- <hr size="2" width="20%">
- <p>You can explicitly compare the gamuts of your video space and
- your display using the gamut tools:<br>
- </p>
- <p><tt>&nbsp; iccgamut -ff -ia Rec709</tt><tt><br>
- </tt><tt> &nbsp; iccgamut -ff -ia TV.icm</tt><tt><br>
- </tt><tt> &nbsp; viewgam -i Rec709.gam TV.gam gamuts</tt><br>
- </p>
- <p>and look at the gamuts.x3d.html file, as well as taking notice of
- % of the video volume that the display intersects. The X3DOM solid
- volume will be the video gamut, while the wire frame is the
- display gamut. If you are not targetting D65 with your display,
- you should use iccgamut <b>-ir</b> instead of <b>-ia</b>, so as
- to align the white points.<br>
- </p>
- <hr size="2" width="20%">
- <p>The main verification check is to actually measure the display

- display is setup as you would for video playback and then use
- dispread:<br>
- </p>
- <p><tt>&nbsp; copy verify.ti1 checkB.ti1</tt><tt><br>
- </tt><tt> &nbsp; dispread -v -Z8 checkB</tt><br>
- </p>
- <p>You would add any other options needed (such as <b>-y</b> etc.)
- to set your instrument up properly. If you are using madTPG, then
- configure madVR to use the 3dLut you want to measure as the
- default, and also use the dispread -V flag to make sure that the
- 3dLut is being used for the measurements: [<b>Note</b> that if the
- version of MadVR you are using does not have radio buttons in its
- calibration setup to indicate a default 3dLut, then the 3dLut
- under test should be the only one set - all others should be
- blank. ]<br>

- </tt></p>
- <p>If your display does not cover the full gamut of your video
- source, the errors are probably dominated by out of gamut colors.
- You can verify just the in gamut test values by asking verify to

+ <h2> <u>Conversion to/from XRGA<br>
+ </u></h2>
+ After purchasing Gretag-Macbeth, X-Rite harmonized the subtly
+ different calibration standards the two companies were using for
+ their reflective measurement instruments, in order to minimize
+ changes with the introduction of new instruments. The result was the
+ <a href="http://www.xrite.com/xrite-graphic-arts-standard">XRGA
+ standard</a>, introduced in September 2010.<br>
+ <br>
+ Current X-Rite instruments are natively calibrated to XRGA, while
+ older instruments from X-Rite are calibrated to XRDI, and
+ Gretag-Macbeth instruments to GMDI standards. To smooth the
+ interchange of old and new instruments, a spectral <a
+href="https://www.xrite.com/documents/literature/en/L7-462_XRGA_WhitePaper_en.pdf">conversion
+
+
+ is possible</a> between these different standards. While such a
+ conversion is not perfect, it reduces the discontinuities between
+ old instrument families and current X-Rite instruments.<br>
+ <br>
+ By default, Argyll will use the native calibration of Gretag-Macbeth
+ and X-Rite instruments. These are summarized here:<br>

+ There are two ways of specifying a source gamut 1) Specify a

+ colors that are up to the percentage outside the devices gamut will
+ be compressed to fit into it. The same percentage is used for
+ expansion if a saturation table is generated, or a separate
+ percentage can be specified by including both a <b>-s</b> and <b>-S</b>
+ percentage. You can optionally specify <u>both</u> and input ICC
+ profile and a general compression percentage by using the -S option
+ twice, in which case the input profile determines just the luminance
+ range mapping, with the percentage determining the gamut volume
+ compression. If a percentage compression is specified without an ICC
+ profile, then the incoming luminance range will be assumed to be
+ full range (perfect white to perfect black), which is compatible
+ with idealized colorspaces such as sRGB, AdobeRGB and other working

- This is the tool is used for adjusting and calibrating a display to
- reach specified target behaviour, and optionally profiling it.&nbsp;
- For best results on a CRT, you should run this against a neutral
- grey desktop background, and avoid having any bright images or
- windows on the screen at the time you run dispcal. You could also
- use the <span style="font-weight: bold;">-B</span> option to black
- the whole screen out, although this will make it impossible to
- control dispcal unless you have more than one display.<br>
- <br>
- <a name="v"></a> The <b>-v</b> flag reports progress information,
- as well as other statistics about the progress of calibration. A
- numerical argument greater than 1 gives greater verbosity. 2 will
- give per step adjustment and repeat information, while 3 will give
- even greater technical detail.<br>
- <br>
- <a name="display"></a>When running on a UNIX based system that used
- the X11 Windowing System, <b>dispcal</b> will by default use the
- $DISPLAY environment variable to determine which local or remote
- display and screen to read from. This can be overridden by supplying
- an X11 display name to the <span style="font-weight: bold;">-display</span>
- option. Note that if Xinerama is active, you can't select the screen
- using $DISPLAY or -display, you have to select it using the <span
- style="font-weight: bold;">-d</span> parameter.<br>
- <br>
- <a name="d"></a> By default the main display will be the location of
- the test window. If the system has more than one display or screen,
- an alternate display/screen can be selected with the <span
- style="font-weight: bold;">-d</span> parameter. If you invoke <span
- style="font-weight: bold;">dispcal</span> so as to display the
- usage information (i.e. "dispcal -?" or "dispcal --"), then the
- discovered displays/screens will be listed. Multiple displays may
- not be listed, if they appear as a single display to the operating
- system (ie. the multi-display support is hidden in the video card
- driver). On UNIX based system that used the X11 Windowing System,
- the <span style="font-weight: bold;">-d</span> parameter will
- override the screen specified by the $DISPLAY or parameter.<br>
- <br>
- <span style="font-weight: bold;">Note</span> that if VideoLUTs for a
- display are not accessible (i.e. no hardware calibration
- capability), <span style="font-weight: bold;">dispcal</span> will
- will issue a warning, but continue creating a calibration based on
- the display "as-is" rather than its native response. See the <a
- href="dispcal.html#o">-o</a> flag for an explanation of the
- implications of having no access to the VideoLUTs.<br>
- <br>
- On X11 the inability to access VideoLUTs could be because you are
- trying to access a remote display, and the remote display doesn't
- support the XF86VidMode extension, or perhaps you are running
- multiple monitors using NVidia TwinView, or MergedFB, and trying to
- access anything other than the primary monitor. TwinView and
- MergedFB don't properly support the XF86VidMode extension for
- multiple displays. You can use <a href="dispwin.html#r">dispwin -r</a>
- to test whether the VideoLUTs are accessible for a particular
- display. See also below, on how to select a different display for
- VideoLUT access. Also note that dispcal will fail if the Visual
- depth doesn't match the VideoLUT depth. Typically the VideoLUTs have
- 256 entries per color component, so the Visual generally needs to be
- 24 bits, 8 bits per color component.<br>

+ This is the tool is used for adjusting and calibrating a display to
+ reach specified target behaviour, and optionally profiling it.&nbsp;
+ For best results on a CRT, you should run this against a neutral
+ grey desktop background, and avoid having any bright images or
+ windows on the screen at the time you run dispcal. You could also
+ use the <span style="font-weight: bold;">-B</span> option to black
+ the whole screen out, although this will make it impossible to
+ control dispcal unless you have more than one display.<br>
+ <br>
+ <a name="v"></a> The <b>-v</b> flag reports progress information,
+ as well as other statistics about the progress of calibration. A
+ numerical argument greater than 1 gives greater verbosity. 2 will
+ give per step adjustment and repeat information, while 3 will give
+ even greater technical detail.<br>
+ <br>
+ <a name="display"></a>When running on a UNIX based system that used
+ the X11 Windowing System, <b>dispcal</b> will by default use the
+ $DISPLAY environment variable to determine which local or remote
+ display and screen to read from. This can be overridden by supplying
+ an X11 display name to the <span style="font-weight: bold;">-display</span>
+ option. Note that if Xinerama is active, you can't select the screen
+ using $DISPLAY or -display, you have to select it using the <span
+ style="font-weight: bold;">-d</span> parameter.<br>
+ <br>
+ <a name="d"></a> By default the main display will be the location of
+ the test window. If the system has more than one display or screen,
+ an alternate display/screen can be selected with the <span
+ style="font-weight: bold;">-d</span> parameter. If you invoke <span
+ style="font-weight: bold;">dispcal</span> so as to display the
+ usage information (i.e. "dispcal -?" or "dispcal --"), then the
+ discovered displays/screens will be listed. Multiple displays may
+ not be listed, if they appear as a single display to the operating
+ system (ie. the multi-display support is hidden in the video card
+ driver). On UNIX based system that used the X11 Windowing System,
+ the <span style="font-weight: bold;">-d</span> parameter will
+ override the screen specified by the $DISPLAY or parameter.<br>
+ <br>
+ <span style="font-weight: bold;">Note</span> that if VideoLUTs for a
+ display are not accessible (i.e. no hardware calibration
+ capability), <span style="font-weight: bold;">dispcal</span> will
+ will issue a warning, but continue creating a calibration based on
+ the display "as-is" rather than its native response. See the <a
+ href="dispcal.html#o">-o</a> flag for an explanation of the
+ implications of having no access to the VideoLUTs.<br>
+ <br>
+ On X11 the inability to access VideoLUTs could be because you are
+ trying to access a remote display, and the remote display doesn't
+ support the XF86VidMode extension, or perhaps you are running
+ multiple monitors using NVidia TwinView, or MergedFB, and trying to
+ access anything other than the primary monitor. TwinView and
+ MergedFB don't properly support the XF86VidMode extension for
+ multiple displays. You can use <a href="dispwin.html#r">dispwin -r</a>
+ to test whether the VideoLUTs are accessible for a particular
+ display. See also below, on how to select a different display for
+ VideoLUT access. Also note that dispcal will fail if the Visual
+ depth doesn't match the VideoLUT depth. Typically the VideoLUTs have
+ 256 entries per color component, so the Visual generally needs to be
+ 24 bits, 8 bits per color component.<br>

- to speed up the process of keeping a display in calibration the <span
- style="font-weight: bold;">-u</span> flag can be used. This uses
- the same calibration targets as the previous calibration but does a
- smaller number of refinement passes, enough to improve the accuracy
- of the calibration to account for drift in the device. If the <span

- this can be overridden using the <span style="font-weight: bold;">-q</span>

- passes will be done, the tighter will be the accuracy tolerance, and
- the more detailed will be the calibration of the display. The result
- will ultimately be limited by the accuracy of the instrument, the
- repeatability of the display and instrument, and the resolution of
- the Video Lookup table entries and Digital or Analogue output
- (RAMDAC).<br>

- <a name="p"></a>The <span style="font-weight: bold;">-p</span> flag

+ <a name="O"></a>The <b>-O</b> parameter allows setting of the

+ the parameter, and not mistaken for the start of another flag, or as
+ a final command line parameter. Many programs that deal with ICC
+ profiles use the description tag to identify a profile, rather than
+ the profile filename, so using a descriptive string is important in
+ being able to find a profile. By default, the profile file name will
+ be used as the description.<br>
+ <br>
+ <a name="u"></a><span style="font-weight: bold;">-u</span> Normally
+ <span style="font-weight: bold;">dispcal</span> creates a new
+ calibration file and optional profile, based on the requested

+ of time, particularly if a high quality level has been selected, so
+ to speed up the process of keeping a display in calibration the <span
+ style="font-weight: bold;">-u</span> flag can be used. This uses
+ the same calibration targets as the previous calibration but does a
+ smaller number of refinement passes, enough to improve the accuracy
+ of the calibration to account for drift in the device. If the <span
+ style="font-weight: bold;">-o</span> flag is used as well, then
+ the ICC profile <span style="font-weight: bold;"></span>will have
+ its vcgt tag updated with the new calibration. This keeps the
+ profile up to date with the display. Normally <span
+ style="font-weight: bold;">dispcal -u</span> will use the same
+ quality level that was specified in the previous calibration, but
+ this can be overridden using the <span style="font-weight: bold;">-q</span>
+ flag. Any options that attempt to change the calibration target (ie.
+ white point, brightness, gamma etc.) will be ignored. Adjustment of

+ <a name="q"></a>&nbsp; Quality - Low, Medium (def), High. The <span

+ passes will be done, the tighter will be the accuracy tolerance, and
+ the more detailed will be the calibration of the display. The result
+ will ultimately be limited by the accuracy of the instrument, the

+ (RAMDAC).<br>
+ <br>
+ <a name="p"></a>The <span style="font-weight: bold;">-p</span> flag

- from white point to black point). If there is too much coloration
- near black, try a larger value, e.g. 6.0 or 8.0.<br>
- <br>
- <a name="bhack"></a>The <b>-b</b> flag forces source 0,0,0 to map
- to destination 0,0,0. This may be useful with displays that have a
- very dark black point, and with an instrument is unable to measure
- it precisely, and where it is known in some other way that the
- display is <u>very well behaved</u> from black (i.e. that it has no
- "dead zone" above zero device input). Using this option with a
- display that is <u>not</u> well behaved, may result in a loss of
- shadow detail. This will override any <b>-k</b> factor.<br>
- <br>
- <a name="B"></a><span style="font-weight: bold;">-B</span>&nbsp; Set
- the target brightness of black in cd/m^2 (i.e. the absolute Y

- <a name="e"></a><span style="font-weight: bold;">-e [n]</span> Run <span
- style="font-weight: bold;">n</span> verify passes on the final
- curves. This is an extra set of instrument readings, that can be
- used to estimate how well the device will match the targets with the
- computed calibration curves. Note that the usefulness of the
- verification is sometimes limited by the repeatability of the device
- &amp; instrument readings. This is often evident for CRT displays,
- which (due to their refresh rate) flicker. More than one
- verification pass can be done by providing the parameter <span
- style="font-weight: bold;">n</span>, and by then comparing the
- successive verifications, some idea of the repeatability can be
- ascertained. The verification uses a fixed number of semi-random
- test values to test the calibration.<br>
- <br>
- <a name="z"></a><span style="font-weight: bold;">-z</span> Run

- establish the expected (target) characteristic. <span
- style="font-weight: bold;">Note</span> that if the initial
- calibration was modified due to it being out of gamut of the
- display, verify will show the resulting discrepancy. You can use <a

- style="font-weight: bold;">.cal</span> file into the display
- before running dispcal <span style="font-weight: bold;">-z</span>.
- Note that if you set an Ambient light level interactively during the
- calibration, you need to enter the same number that was measured and
- set using the <span style="font-weight: bold;">-a</span> parameter
- for verify.<br>
- <br>
- <a name="P"></a> The <span style="font-weight: bold;">-P</span>
- parameter allows you to position and size the test patch window. By
- default it is places in the center of the screen, and sized
- appropriately for the type of instrument, or 10% of the width of the
- display if the display size is unknown.. The <span
- style="font-weight: bold;">ho</span> and <span
- style="font-weight: bold;">vo</span> values govern the horizontal
- and vertical offset respectively. A value of 0.0 positions the
- window to the far left or top of the screen, a value of 0.5
- positions it in the center of the screen (the default), and 1.0
- positions it to the far right or bottom of the screen. If three
- parameters are provided, then the <span style="font-weight: bold;">ss</span>
- parameter is a scale factor for the test window size. A value of 0.5
- for instance, would produce a half sized window. A value of 2.0 will
- produce a double size window. If four parameters are provided, then
- the last two set independent horizontal and vertical scaling
- factors. Note that the ho,vo,ss or ho,vo,hs,vs numbers must be
- specified as a single string (no space between the numbers and the
- comma). For example, to create a double sized test window at the top
- right of the screen, use <span style="font-weight: bold;">-P 1,0,2</span>
- . To create a window twice as wide as high: <span
- style="font-weight: bold;">-P 1,0,2,1</span>.<br>
- <br>
- <a name="F"></a> The <span style="font-weight: bold;">-F</span>
- flag causes the while screen behind the test window to be masked
- with black. This can aid black accuracy when measuring CRT displays
- or projectors.<br>
- <br>
- <a name="E"></a> The <span style="font-weight: bold;">-E</span>
- flag causes the display test values to be scaled to the Video RGB
- encoding range of (16-235)/255. This also modifies the resulting
- calibration curve behavior downstream of dispcal. If a calibration
- curve created using -E gets installed or converted to an ICC profile
- 'vcgt' tag in the process of creating a profile in dispcal or
- colprof, the incoming full range values will first have the
- calibration curve applied and then be scaled to the Video encoding
- range (16-235)/255.<br>
- <br>
- <a name="n"></a><span style="font-weight: bold;">-n</span> When
- running on a UNIX based system that used the X11 Windowing System, <b>dispcal</b>
- normally selects the override redirect so that the test window will
- appear above any other windows on the display. On some systems this
- can interfere with window manager operation, and the <b>-n</b>
- option turns this behaviour off.<br>
- <br>
- <a name="J"></a> The -<span style="font-weight: bold;">J</span>
- option runs through the black and sensor relative calibration
- routines for the Xrite DTP92 and DTP94 instruments, the black level
- calibration for the Eye-One Display 1, and a CRT frequency
- calibration for the Eye-One Display 2. For the black calibration the
- instrument should be placed on an opaque, black surface, and any
- stray light should be avoided by placing something opaque over the
- instrument. If a Spectrolino is being used, then a white and black
- calibration will always be performed before the instrument can be
- placed on the display, unless the <a href="dispcal.html#N">-N</a>
- flag is used. Generally it is not necessary to do a calibration
- every time an instrument is used, just now and again. There is also
- no point in doing&nbsp; a CRT frequency calibration, as this will be
- done automatically at the commencement of patch reading, and will be
- lost between runs.<br>
- <br>
- <a name="N"></a> <span style="font-weight: bold;">-N</span> Any
- instrument that requires regular calibration will ask for
- calibration on initial start-up. Sometimes this can be awkward if
- the instrument is being mounted in some sort of measuring jig, or
- annoying if several sets of readings are being taken in quick
- succession. The -<span style="font-weight: bold;">N</span>
- suppresses this initial calibration if a valid and not timed out
- previous calibration is recorded in the instrument or on the host
- computer. It is advisable to only use this option on the second and
- subsequent measurements in a single session.<br>
- <br>
- <a name="H"></a> The -<span style="font-weight: bold;">H</span>
- option turns on high resolution spectral mode, if the instrument
- supports it, such as the Eye-One Pro. See <a
- href="instruments.html">Operation of particular instruments</a>
- for more details. This may give better accuracy for display
- measurements.<br>
- <br>
- <a name="X1"></a> The -<span style="font-weight: bold;">X <span
- style="font-style: italic;">file.ccmx</span></span> option reads
- a <a href="File_Formats.html#.ccmx">Colorimeter Correction Matrix</a>
- from the given file, and applies it to the colorimeter instruments
- readings. This can improve a colorimeters accuracy for a particular
- type of display. A list of contributed <span style="font-weight:

- <br>
- <a name="X2"></a> The -<span style="font-weight: bold;">X <span
- style="font-style: italic;">file.ccss</span></span> option reads
- a <a href="File_Formats.html#.ccss">Colorimeter Calibration
- Spectral Sample</a> from the given file, and uses it to set the
- colorimeter instruments calibration. This will only work with
- colorimeters that rely on sensor spectral sensitivity calibration
- information (ie. the X-Rite <span style="font-weight: bold;">i1d3</span>,
- or the DataColor <span style="font-weight: bold;">Spyder4 &amp;
- Spyder 5</span>).This can improve a colorimeters accuracy for a
- particular type of display.<br>
- <br>
- <a name="Q"></a> The <b>-Q</b> flag allows specifying a tristimulus
- observer, and is used to compute PCS (Profile Connection Space)
- tristimulus values from spectral readings or using a colorimeter
- that has CCSS capability. The following choices are available:<br>
- <b>&nbsp; 1931_2</b> selects the standard CIE 1931 2 degree

- <br>
- <span style="font-weight: bold;">NOTE</span> that if you select
- anything other than the default 1931 2 degree observer, that the Y
- values will not be cd/m^2, due to the Y curve not being the CIE 1924
- photopic V(&#955;) luminosity function.<br>
- <br>
- <a name="I"></a> The -<span style="font-weight: bold;">I <span
- style="font-style: italic;">b|w</span></span> options invoke
- instrument black level, and display white level compensation
- (respectively). Instrument black level drift compensation attempts
- to combat instrument black calibration drift by using a display
- black test patch as a reference. If an instrument is not
- acclimatised sufficiently to the measurement conditions, changes in
- temperature can affect the black readings. Display white level drift
- compensation attempts to combat changes in display brightness as it
- warms up by measuring a white patch every so often, and using it to
- normalise all the other readings. If just instrument black drift
- compensation is needed, use <span style="font-weight: bold;">-Ib</span>.
- If just display white level compensation is needed, use <span
- style="font-weight: bold;">-Iw</span>. If both are needed, use <span
- style="font-weight: bold;">-Ibw</span> or <span

- <br>
- <a name="YR"></a> The -<span style="font-weight: bold;">Y R:<i>rate</i></span>
- options overrides calibration of the instrument refresh rate. This
- may be useful if the instrument supports this function and the
- refresh rate cannot be accurately calibrated from the display
- itself.<br>
- <br>
- <a name="YA"></a> The -<span style="font-weight: bold;">Y A</span>
- option uses a non-adaptive integration time emission measurement
- mode, if the instrument supports it, such as the Eye-One Pro,
- ColorMunki, i1d3 and K10. By default an adaptive integration time
- measurement mode will be used for emission measurements, but some
- instruments support a fixed integration time mode that can be used
- with display devices. This may give faster measurement times, but
- may also give less accurate low level readings.<br>
- <br>
- <a name="Yp"></a> The -<span style="font-weight: bold;">Y p</span>
- option skips asking the user to place the instrument on the display.
- Normally a grey patch is displayed, and then the user is asked to
- confirm that the instrument is in place, so that readings can
- commence. This flag disables that check. This may be useful in
- automating certain operations.<br>
- <br>
- <a name="C"></a> The -<span style="font-weight: bold;">C</span> <span
- style="font-weight: bold;">"command" </span>option allows a
- method of relaying each test value to some other display than that
- on the system running dispcal (for instance, a photo frame, PDA
- screen etc.), by causing the given command to be invoked to the
- shell, with six arguments. The first three arguments are the RGB
- test color as integers in the range 0 to 255, the second three
- parameters are the RGB test color as floating point numbers in the
- range 0.0 to 1.0. The script or tool should relay the given color to
- the screen in some manner (e.g. by generating a raster file of the
- given color and sending it to the display being profiled), before
- returning. Note that a test window will also be created on the
- system running dispread.<br>
- <br>
- <a name="M"></a> The -<span style="font-weight: bold;">M</span> <span
- style="font-weight: bold;">"command" </span>option allows a
- method of gathering each test value from some external source, such
- as an instrument that is not directly supported by Argyll. The given
- command is involked to the shell, with six arguments. The first
- three arguments are the RGB test color as integers in the range 0 to
- 255, the second three parameters are the RGB test color as floating
- point numbers in the range 0.0 to 1.0. The script or tool should
- create a file called <span style="font-weight: bold;">"command.meas</span>"
- that contains the XYZ values for the given RGB (or measured from the
- test window) in cd/m^2 as three numbers separated by spaces, before
- returning. If the command returns a non-zero return value, dispcal
- will abort. Note that a test window will also be created on the
- system running dispcal.<br>
- <br>
- <a name="W"></a>The <b>-W</b> <span style="font-weight: bold;">n|h|x</span>
- parameter overrides the default serial communications flow control
- setting. The value <span style="font-weight: bold;">n</span> turns
- all flow control off, <span style="font-weight: bold;">h</span>
- sets hardware handshaking, and <span style="font-weight: bold;">x</span>
- sets Xon/Xoff handshaking. This commend may be useful in workaround
- serial communications issues with some systems and cables. <br>
- <br>
- <a name="D"></a>The <b>-D</b> flag causes communications and other
- instrument diagnostics to be printed to stdout. A level can be set
- between 1 .. 9, that may give progressively more verbose
- information, depending on the instrument. This can be useful in
- tracking down why an instrument can't connect.<br>
- <br>
- <a name="p1"></a><span style="font-weight: bold;">inoutfile</span>
- The final parameter on the command line is the base filename for the
- <a href="cal_format.html">.cal</a> file and the optional ICC
- profile. Normally this will be created (or an existing file will be
- overwritten). If the <span style="font-weight: bold;">-u</span>
- flag is used, then these files will be updated. If a different ICC

- style="font-weight: bold;">-o</span> flag.<br>
- <br>
- <span style="font-weight: bold;">NOTE</span> that on an X11 system,
- if the environment variable <span style="font-weight: bold;">ARGYLL_IGNORE_XRANDR1_2</span>
- is set (ie. set it to "yes"), then the presence of the XRandR 1.2

- <h2><a name="Adjustment"></a>Discussion and guide to display control
- adjustment:</h2>
- <br>
- The adjustment of the display controls (brightness, contrast, R, G
- &amp; B channel controls etc.) is very dependent on the particular
- monitor. Different types and brands of monitors will have different
- controls, or controls that operate in different ways. Some displays
- have almost no user controls, and so you may well be best skipping
- display adjustment, and going straight to calibration.<br>
- <br>
- Almost all LCD displays lack a real <span style="font-weight:
- bold;">contrast</span> control. Those that do present such a
- control generally fake it by adjusting the video signal. For this
- reason it is usually best to set an LCD's <span style="font-weight:
- bold;">contrast</span> control at its neutral setting (ie. the
- setting at which it doesn't change the video signal). Unfortunately,
- it can be hard to know what this neutral setting is. On some
- displays it is 50%, others 75%. If the LCD display has a "reset to
- factory defaults" mode, then try using this first, as a way of
- setting the <span style="font-weight: bold;">contrast</span>
- control to neutral. The LCD <span style="font-weight: bold;">brightness</span>
- control generally adjusts the level of backlighting the display
- gets, which affects the maximum brightness, and also tends to raise
- or lower the black level in proportion, without changing the
- displays response curve shape or overall contrast ratio. If your LCD
- display has a <span style="font-weight: bold;">backlight</span>
- control as well as a <span style="font-weight: bold;">brightness</span>
- control, then the brightness control is also probably being faked,
- and you are probably better off setting it to it's neutral setting,
- and using the <span style="font-weight: bold;">backlight</span>
- control in place of <span style="font-weight: bold;">brightness</span>
- in the following adjustments.<br>
- <br>
- Some high end displays have the ability to mimic various standard
- colorspaces such as sRGB or AdobeRGB. You could choose to calibrate
- and profile the display in such an emulation mode, although you
- probably don't want to fight the emulations white point and gamma.
- To get the best out of such a display you really want to choose it's
- "Native Gamut" setting, whatever that is called. Note that some
- people have reported bad experiences in trying to use "6-axis custom
- controls" on displays such as the Dell U2410, so attempting to use
- such a mode should be approached with caution. Ideally such a mode
- should be used to give just the underlying native display response,
- but the settings to achieve this may be very difficult to determine,
- and/or it may not be possible, depending on how such a mode distorts
- the RGB signals.<br>
- <br>
- On CRT based displays, the <span style="font-weight: bold;">brightness</span>
- control generally adjusts the black level of the display (sometimes
- called the <span style="font-weight: bold;">offset</span>), and as
- a side effect, tends to change the maximum brightness too. A CRT <span
- style="font-weight: bold;">contrast</span> control generally
- adjusts the maximum brightness (sometimes called <span
- style="font-weight: bold;">gain</span>) without affecting the
- black level a great deal. On a CRT both the <span
- style="font-weight: bold;">brightness</span> and <span
- style="font-weight: bold;">contrast</span> controls will tend to
- affect the shape or gamma of the display response curve.<br>
- <br>
- Many displays have some sort of color temperature adjustment. This
- may be in the form of some pre-set color temperatures, or in the
- form of individual Red, Green and Blue channel gain adjustments.
- Some CRT displays also have R, G &amp; B channel offset adjustments
- that will affect the color temperatures near black, as well as
- affect the individual channels curve shape. The color temperature
- adjustment will generally affect the maximum brightness, and may
- also affect the black level and the shape of the display response
- curves.<br>
- <br>
- Some special (expensive) LCD displays may have a white point
- adjustment that changes the color of the backlight. If you do not
- have one of these types of LCD displays, then attempting to change
- the white point of the display (even if it appears to have a "<span
- style="font-weight: bold;">white point selection</span>" or <span
- style="font-weight: bold;">R/G/B</span> "<span style="font-weight:
- bold;">gain</span>" controls") may not be a good idea, as once
- again these controls are probably being faked by manipulating the
- signal levels. Even if you do manage to change the white point
- significantly, it may do things like change the mid tone color too
- dramatically, or create a display response that is hard to correct
- with calibration, or results in side effects such as quantization
- (banding) or other undesirable effects. You may have to try out
- various controls (and your aim points for the display calibration),
- to decide what is reasonable to attempt on an LCD display.<br>
- <br>
- Due to the variety of controls as well as the interaction between
- them, it can be an iterative process to arrive at a good monitor
- set-up, before proceeding on to calibrating and profiling a display.
- For this reason, <span style="font-weight: bold;">dispcal</span>
- offers a menu of adjustment modes, so that the user can
- interactively and iteratively adjust the display controls to meet
- the desired targets.<br>
- <br>
- &nbsp; 1) Black level (CRT: Brightness)<br>
- &nbsp; 2) White point (Color temperature, R,G,B, Gain/Contrast)<br>
- &nbsp; 3) White level (CRT: Gain/Contrast, LCD:
- Brightness/Backlight)<br>
- &nbsp; 4) Black point (R,G,B, Offset/Brightness)<br>
- &nbsp; 5) Check all<br>
- &nbsp; 6) Measure and set ambient for viewing condition adjustment<br>
- &nbsp; 7) Continue on to calibration<br>
- &nbsp; 8) Exit<br>
- <br>
- There are four basic adjustment modes. Normally one would proceed
- through them in the order above, then perhaps repeat the first
- adjustment, before checking the overall settings. The White point
- and White level modes operate slightly differently, depending on
- whether a white target point has been set using the <span
- style="font-weight: bold;">-t -T</span> or <span
- style="font-weight: bold;">-w</span> options, and on whether a
- brightness target has been set using the <span style="font-weight:
- bold;">-b</span> option.<br>
- <br>
- <br>
- The first mode lets you adjust the black level of a CRT display.
- Given the current white level, it calculates a value that should
- produce a 1% display brightness if the black level is set correctly.
- After doing some initial measurements, it will show the target
- brightness value (in cd/m^2) on one line, and then underneath it
- will show continuously updated readings from the display. The left
- most character will switch from '\' to '/' or back again each time a
- reading is updated. Some instruments can be quite slow in measuring
- dark colors, and it's best to wait for a reading update before
- changing the controls more than once. Underneath the target value is
- displayed the current reading, and to the right of this is a '+',
- '-' or '=' symbol, which gives a hint as to which way to adjust the
- brightness control to improve the match to the target.<br>

- Once happy with the adjustment, press space to go back to the menu.<br>
- <br>
- <br>
- The second mode lets you adjust the color of the white point of the
- display. If a target white point has been set, it will show the
- target brightness value (in cd/m^2) on one line, together with the
- target chromaticity co-ordinates for the white point, and then
- underneath it will show continuously updated readings from the
- display. The left most character will switch from '\' to '/' or back
- again each time a reading is updated. Underneath the target
- brightness value is displayed the current reading, and then the
- current chromaticity co-ordinate values. To the right of this is the
- current delta E of the white point from the target, and further to
- the right are hints '+', '-' or '='&nbsp; as to which direction to
- adjust the individual Red, Green and Blue gain settings to move the
- white point in the direction of the target, and reduce the delta E.
- If the symbol is doubled, then this channel will have the greatest
- effect. If you do not have individual channel gain controls, then
- try choosing amongst color temperature pre-sets, to find one with
- the lowest delta E. Depending on the stability of the display, the
- coarseness of the controls, and the repeatability of the instrument,
- you may not be able to get a perfectly zero delta E.<br>

- set). The constantly updated values show the same thing, and the
- Red, Green and Blue control hints show the direction to adjust the
- controls to place the white point on the locus. The control that
- will have the most direct effect on the color temperature will be
- the Blue, while the Green will most directly move the white point

- <h2>Other caveats:</h2>
- NOTE that some <span style="font-weight: bold;">LCD</span> screens
- behave a little strangely near their absolute white point, and may
- therefore exhibit odd behavior at values just below white. It may be
- advisable in such cases to set a brightness slightly less than the
- maximum such a display is capable of.<br>
- <br>
- The program attempts to stop any screensaver or powersaver from
- interfering with the measurements, but this may not be effective on
- some systems, so it may be necessary to manually disable the
- screensaver and/or powersaver before commencing the calibration with
- a large number of patches.<br>
- <br>
- The calibration tables produced maintain the maximum level of
- precision available on a system. If the display has VideoLUTs
- available (Video Lookup Tables that the frame buffer values pass
- through on their way to the display) and thier outputs are better
- than 8 bits per component, then the resulting curves can reflect
- this, although few current operating systems and/or display cards
- actually support better than 8 bit per component output.<br>
- <br>
- If calibration curves are created for a display in which VideoLUTs
- are not available, then the resulting calibration file will be
- marked to indicate this, and a subsequent profile created with the
- calibration will not have the calibration converted to the 'vcgt'
- tag, since such a tag can't be loaded into the displays VideoLUTs.<br>
- <br>
- If communications break down with a USB connected instrument, you
- may have to unplug it, and plug it in again to recover operation.<br>
- <br>
- Some systems (Apple OS X in particular) have a special set of user
- interface controls ("Universal Access") that allows altering the
- display in ways designed to assist visually impaired users, by
- increasing contrast etc. This will interfere badly with any attempts
- to calibrate or profile such a system, and must be turned off in
- order to do so. Note that certain magic keyboard sequences can turn
- this on by accident.<br>

+
+ the black point is not being set completely to the same hue as the
+ white point (ie. because the <span style="font-weight: bold;">-k</span>
+ factor is less than 1.0), then the resulting calibration curves will
+ have the target white point down most of the curve, but will then
+ blend over to the native or compromise black point that is blacker,
+ but not of the right hue. The rate of this blend can be controlled
+ with the <span style="font-weight: bold;">-A</span> parameter. The
+ default value 4.0, which results in a target that switches from the
+ white point target to the black, moderately close to the black
+ point. While this typically gives a good visual result with the
+ target neutral hue being maintained to the point where the crossover
+ to the black hue is not visible, it may be asking too much of some
+ displays (typically LCD type displays), and there may be some visual
+ effects due to inconsistent color with viewing angle. For this
+ situation a smaller value may give a better visual result (e.g. try
+ values of 3.0 or 2.0. A value of 1.0 will set a pure linear blend
+ from white point to black point). If there is too much coloration
+ near black, try a larger value, e.g. 6.0 or 8.0.<br>
+ <br>
+ <a name="bhack"></a>The <b>-b</b> flag forces source 0,0,0 to map
+ to destination 0,0,0. This may be useful with displays that have a
+ very dark black point, and with an instrument is unable to measure
+ it precisely, and where it is known in some other way that the
+ display is <u>very well behaved</u> from black (i.e. that it has no
+ "dead zone" above zero device input). Using this option with a
+ display that is <u>not</u> well behaved, may result in a loss of
+ shadow detail. This will override any <b>-k</b> factor.<br>
+ <br>
+ <a name="B"></a><span style="font-weight: bold;">-B</span>&nbsp; Set
+ the target brightness of black in cd/m^2 (i.e. the absolute Y
+ value). Setting too high a value may give strange results as it
+ interacts with trying to achieve the target "advertised" gamma curve
+ shape. You could try using -f 1 if this causes a problem.<br>
+ <br>
+ <a name="e"></a><span style="font-weight: bold;">-e [n]</span> Run <span
+ style="font-weight: bold;">n</span> verify passes on the final
+ curves. This is an extra set of instrument readings, that can be
+ used to estimate how well the device will match the targets with the
+ computed calibration curves. Note that the usefulness of the
+ verification is sometimes limited by the repeatability of the device
+ &amp; instrument readings. This is often evident for CRT displays,
+ which (due to their refresh rate) flicker. More than one
+ verification pass can be done by providing the parameter <span
+ style="font-weight: bold;">n</span>, and by then comparing the
+ successive verifications, some idea of the repeatability can be
+ ascertained. The verification uses a fixed number of semi-random
+ test values to test the calibration.<br>
+ <br>
+ <a name="z"></a><span style="font-weight: bold;">-z</span> Run
+ verify pass on the display as it is currently setup (currently
+ installed LUT curves). This will use the usual input parameters to
+ establish the expected (target) characteristic. <span
+ style="font-weight: bold;">Note</span> that if the initial
+ calibration was modified due to it being out of gamut of the
+ display, verify will show the resulting discrepancy. You can use <a
+ href="dispwin.html">dispwin</a> to load a <span
+ style="font-weight: bold;">.cal</span> file into the display
+ before running dispcal <span style="font-weight: bold;">-z</span>.
+ Note that if you set an Ambient light level interactively during the
+ calibration, you need to enter the same number that was measured and
+ set using the <span style="font-weight: bold;">-a</span> parameter
+ for verify.<br>
+ <br>
+ <a name="P"></a> The <span style="font-weight: bold;">-P</span>
+ parameter allows you to position and size the test patch window. By
+ default it is places in the center of the screen, and sized
+ appropriately for the type of instrument, or 10% of the width of the
+ display if the display size is unknown.. The <span
+ style="font-weight: bold;">ho</span> and <span
+ style="font-weight: bold;">vo</span> values govern the horizontal
+ and vertical offset respectively. A value of 0.0 positions the
+ window to the far left or top of the screen, a value of 0.5
+ positions it in the center of the screen (the default), and 1.0
+ positions it to the far right or bottom of the screen. If three
+ parameters are provided, then the <span style="font-weight: bold;">ss</span>
+ parameter is a scale factor for the test window size. A value of 0.5
+ for instance, would produce a half sized window. A value of 2.0 will
+ produce a double size window. If four parameters are provided, then
+ the last two set independent horizontal and vertical scaling
+ factors. Note that the ho,vo,ss or ho,vo,hs,vs numbers must be
+ specified as a single string (no space between the numbers and the
+ comma). For example, to create a double sized test window at the top
+ right of the screen, use <span style="font-weight: bold;">-P 1,0,2</span>
+ . To create a window twice as wide as high: <span
+ style="font-weight: bold;">-P 1,0,2,1</span>.<br>
+ <br>
+ <a name="F"></a> The <span style="font-weight: bold;">-F</span>
+ flag causes the while screen behind the test window to be masked
+ with black. This can aid black accuracy when measuring CRT displays
+ or projectors.<br>
+ <br>
+ <a name="E"></a> The <span style="font-weight: bold;">-E</span>
+ flag causes the display test values to be scaled to the Video RGB
+ encoding range of (16-235)/255. This also modifies the resulting
+ calibration curve behavior downstream of dispcal. If a calibration
+ curve created using -E gets installed or converted to an ICC profile
+ 'vcgt' tag in the process of creating a profile in dispcal or
+ colprof, the incoming full range values will first have the
+ calibration curve applied and then be scaled to the Video encoding
+ range (16-235)/255.<br>
+ <br>
+ <a name="n"></a><span style="font-weight: bold;">-n</span> When
+ running on a UNIX based system that used the X11 Windowing System, <b>dispcal</b>
+ normally selects the override redirect so that the test window will
+ appear above any other windows on the display. On some systems this
+ can interfere with window manager operation, and the <b>-n</b>
+ option turns this behaviour off.<br>
+ <br>
+ <a name="J"></a> The -<span style="font-weight: bold;">J</span>
+ option runs through the black and sensor relative calibration
+ routines for the Xrite DTP92 and DTP94 instruments, the black level
+ calibration for the Eye-One Display 1, and a CRT frequency
+ calibration for the Eye-One Display 2. For the black calibration the
+ instrument should be placed on an opaque, black surface, and any
+ stray light should be avoided by placing something opaque over the
+ instrument. If a Spectrolino is being used, then a white and black
+ calibration will always be performed before the instrument can be
+ placed on the display, unless the <a href="dispcal.html#N">-N</a>
+ flag is used. Generally it is not necessary to do a calibration
+ every time an instrument is used, just now and again. There is also
+ no point in doing&nbsp; a CRT frequency calibration, as this will be
+ done automatically at the commencement of patch reading, and will be
+ lost between runs.<br>
+ <br>
+ <a name="N"></a> <span style="font-weight: bold;">-N</span> Any
+ instrument that requires regular calibration will ask for
+ calibration on initial start-up. Sometimes this can be awkward if
+ the instrument is being mounted in some sort of measuring jig, or
+ annoying if several sets of readings are being taken in quick
+ succession. The -<span style="font-weight: bold;">N</span>
+ suppresses this initial calibration if a valid and not timed out
+ previous calibration is recorded in the instrument or on the host
+ computer. It is advisable to only use this option on the second and
+ subsequent measurements in a single session.<br>
+ <br>
+ <a name="H"></a> The -<span style="font-weight: bold;">H</span>
+ option turns on high resolution spectral mode, if the instrument
+ supports it, such as the Eye-One Pro. See <a
+ href="instruments.html">Operation of particular instruments</a>
+ for more details. This may give better accuracy for display
+ measurements.<br>
+ <br>
+ <a name="X1"></a> The -<span style="font-weight: bold;">X <span
+ style="font-style: italic;">file.ccmx</span></span> option reads
+ a <a href="File_Formats.html#.ccmx">Colorimeter Correction Matrix</a>
+ from the given file, and applies it to the colorimeter instruments
+ readings. This can improve a colorimeters accuracy for a particular
+ type of display. A list of contributed <span style="font-weight:

+ <br>
+ <a name="X2"></a> The -<span style="font-weight: bold;">X <span
+ style="font-style: italic;">file.ccss</span></span> option reads
+ a <a href="File_Formats.html#.ccss">Colorimeter Calibration
+ Spectral Sample</a> from the given file, and uses it to set the

+ colorimeters that rely on sensor spectral sensitivity calibration
+ information (ie. the X-Rite <span style="font-weight: bold;">i1d3</span>,
+ or the DataColor <span style="font-weight: bold;">Spyder4 &amp;
+ Spyder 5</span>).This can improve a colorimeters accuracy for a
+ particular type of display.<br>
+ <br>
+ <a name="Q"></a> The <b>-Q</b> flag allows specifying a tristimulus
+ observer, and is used to compute PCS (Profile Connection Space)
+ tristimulus values from spectral readings or using a colorimeter
+ that has CCSS capability. The following choices are available:<br>
+ <b>&nbsp; 1931_2</b> selects the standard CIE 1931 2 degree

+ &nbsp; <b>shaw</b> selects the Shaw and Fairchild 1997 2 degree

+ <br>
+ <span style="font-weight: bold;">NOTE</span> that if you select
+ anything other than the default 1931 2 degree observer, that the Y
+ values will not be cd/m^2, due to the Y curve not being the CIE 1924
+ photopic V(&#955;) luminosity function.<br>
+ <br>
+ <a name="I"></a> The -<span style="font-weight: bold;">I <span
+ style="font-style: italic;">b|w</span></span> options invoke
+ instrument black level, and display white level compensation
+ (respectively). Instrument black level drift compensation attempts
+ to combat instrument black calibration drift by using a display
+ black test patch as a reference. If an instrument is not
+ acclimatised sufficiently to the measurement conditions, changes in
+ temperature can affect the black readings. Display white level drift
+ compensation attempts to combat changes in display brightness as it
+ warms up by measuring a white patch every so often, and using it to
+ normalise all the other readings. If just instrument black drift
+ compensation is needed, use <span style="font-weight: bold;">-Ib</span>.
+ If just display white level compensation is needed, use <span
+ style="font-weight: bold;">-Iw</span>. If both are needed, use <span

+ itself.<br>
+ <br>
+ <a name="YA"></a> The -<span style="font-weight: bold;">Y A</span>
+ option uses a non-adaptive integration time emission measurement
+ mode, if the instrument supports it, such as the Eye-One Pro,
+ ColorMunki, i1d3 and K10. By default an adaptive integration time
+ measurement mode will be used for emission measurements, but some
+ instruments support a fixed integration time mode that can be used
+ with display devices. This may give faster measurement times, but
+ may also give less accurate low level readings.<br>
+ <br>
+ <a name="Yp"></a> The -<span style="font-weight: bold;">Y p</span>
+ option skips asking the user to place the instrument on the display.
+ Normally a grey patch is displayed, and then the user is asked to
+ confirm that the instrument is in place, so that readings can
+ commence. This flag disables that check. This may be useful in
+ automating certain operations.<br>
+ <br>
+ <a name="C"></a> The -<span style="font-weight: bold;">C</span> <span
+ style="font-weight: bold;">"command" </span>option allows a
+ method of relaying each test value to some other display than that
+ on the system running dispcal (for instance, a photo frame, PDA
+ screen etc.), by causing the given command to be invoked to the
+ shell, with six arguments. The first three arguments are the RGB
+ test color as integers in the range 0 to 255, the second three
+ parameters are the RGB test color as floating point numbers in the
+ range 0.0 to 1.0. The script or tool should relay the given color to
+ the screen in some manner (e.g. by generating a raster file of the
+ given color and sending it to the display being profiled), before
+ returning. Note that a test window will also be created on the
+ system running dispread.<br>
+ <br>
+ <a name="M"></a> The -<span style="font-weight: bold;">M</span> <span
+ style="font-weight: bold;">"command" </span>option allows a
+ method of gathering each test value from some external source, such
+ as an instrument that is not directly supported by Argyll. The given
+ command is involked to the shell, with six arguments. The first
+ three arguments are the RGB test color as integers in the range 0 to
+ 255, the second three parameters are the RGB test color as floating
+ point numbers in the range 0.0 to 1.0. The script or tool should
+ create a file called <span style="font-weight: bold;">"command.meas</span>"
+ that contains the XYZ values for the given RGB (or measured from the

+ <br>
+ <a name="W"></a>The <b>-W</b> <span style="font-weight: bold;">n|h|x</span>
+ parameter overrides the default serial communications flow control
+ setting. The value <span style="font-weight: bold;">n</span> turns
+ all flow control off, <span style="font-weight: bold;">h</span>
+ sets hardware handshaking, and <span style="font-weight: bold;">x</span>
+ sets Xon/Xoff handshaking. This commend may be useful in workaround
+ serial communications issues with some systems and cables. <br>
+ <br>
+ <a name="D"></a>The <b>-D</b> flag causes communications and other
+ instrument diagnostics to be printed to stdout. A level can be set
+ between 1 .. 9, that may give progressively more verbose

+ tracking down why an instrument can't connect.<br>
+ <br>
+ <a name="p1"></a><span style="font-weight: bold;">inoutfile</span>
+ The final parameter on the command line is the base filename for the

+ <br>
+ <span style="font-weight: bold;">NOTE</span> that on an X11 system,
+ if the environment variable <span style="font-weight: bold;">ARGYLL_IGNORE_XRANDR1_2</span>
+ is set (ie. set it to "yes"), then the presence of the XRandR 1.2

+ <hr style="width: 100%; height: 2px;">
+ <h2><a name="Adjustment"></a>Discussion and guide to display control
+ adjustment:</h2>
+ <br>
+ The adjustment of the display controls (brightness, contrast, R, G
+ &amp; B channel controls etc.) is very dependent on the particular
+ monitor. Different types and brands of monitors will have different
+ controls, or controls that operate in different ways. Some displays
+ have almost no user controls, and so you may well be best skipping
+ display adjustment, and going straight to calibration.<br>
+ <br>
+ Almost all LCD displays lack a real <span style="font-weight:
+ bold;">contrast</span> control. Those that do present such a
+ control generally fake it by adjusting the video signal. For this
+ reason it is usually best to set an LCD's <span style="font-weight:
+ bold;">contrast</span> control at its neutral setting (ie. the
+ setting at which it doesn't change the video signal). Unfortunately,
+ it can be hard to know what this neutral setting is. On some
+ displays it is 50%, others 75%. If the LCD display has a "reset to
+ factory defaults" mode, then try using this first, as a way of
+ setting the <span style="font-weight: bold;">contrast</span>
+ control to neutral. The LCD <span style="font-weight: bold;">brightness</span>
+ control generally adjusts the level of backlighting the display
+ gets, which affects the maximum brightness, and also tends to raise
+ or lower the black level in proportion, without changing the
+ displays response curve shape or overall contrast ratio. If your LCD
+ display has a <span style="font-weight: bold;">backlight</span>
+ control as well as a <span style="font-weight: bold;">brightness</span>
+ control, then the brightness control is also probably being faked,
+ and you are probably better off setting it to it's neutral setting,
+ and using the <span style="font-weight: bold;">backlight</span>
+ control in place of <span style="font-weight: bold;">brightness</span>
+ in the following adjustments.<br>
+ <br>
+ Some high end displays have the ability to mimic various standard
+ colorspaces such as sRGB or AdobeRGB. You could choose to calibrate
+ and profile the display in such an emulation mode, although you
+ probably don't want to fight the emulations white point and gamma.
+ To get the best out of such a display you really want to choose it's
+ "Native Gamut" setting, whatever that is called. Note that some
+ people have reported bad experiences in trying to use "6-axis custom
+ controls" on displays such as the Dell U2410, so attempting to use
+ such a mode should be approached with caution. Ideally such a mode
+ should be used to give just the underlying native display response,
+ but the settings to achieve this may be very difficult to determine,
+ and/or it may not be possible, depending on how such a mode distorts
+ the RGB signals.<br>
+ <br>
+ On CRT based displays, the <span style="font-weight: bold;">brightness</span>
+ control generally adjusts the black level of the display (sometimes
+ called the <span style="font-weight: bold;">offset</span>), and as
+ a side effect, tends to change the maximum brightness too. A CRT <span
+ style="font-weight: bold;">contrast</span> control generally
+ adjusts the maximum brightness (sometimes called <span
+ style="font-weight: bold;">gain</span>) without affecting the
+ black level a great deal. On a CRT both the <span
+ style="font-weight: bold;">brightness</span> and <span
+ style="font-weight: bold;">contrast</span> controls will tend to
+ affect the shape or gamma of the display response curve.<br>
+ <br>
+ Many displays have some sort of color temperature adjustment. This
+ may be in the form of some pre-set color temperatures, or in the
+ form of individual Red, Green and Blue channel gain adjustments.
+ Some CRT displays also have R, G &amp; B channel offset adjustments
+ that will affect the color temperatures near black, as well as
+ affect the individual channels curve shape. The color temperature
+ adjustment will generally affect the maximum brightness, and may
+ also affect the black level and the shape of the display response
+ curves.<br>
+ <br>
+ Some special (expensive) LCD displays may have a white point
+ adjustment that changes the color of the backlight. If you do not
+ have one of these types of LCD displays, then attempting to change
+ the white point of the display (even if it appears to have a "<span
+ style="font-weight: bold;">white point selection</span>" or <span
+ style="font-weight: bold;">R/G/B</span> "<span style="font-weight:
+ bold;">gain</span>" controls") may not be a good idea, as once
+ again these controls are probably being faked by manipulating the
+ signal levels. Even if you do manage to change the white point
+ significantly, it may do things like change the mid tone color too
+ dramatically, or create a display response that is hard to correct
+ with calibration, or results in side effects such as quantization
+ (banding) or other undesirable effects. You may have to try out
+ various controls (and your aim points for the display calibration),
+ to decide what is reasonable to attempt on an LCD display.<br>
+ <br>
+ Due to the variety of controls as well as the interaction between
+ them, it can be an iterative process to arrive at a good monitor
+ set-up, before proceeding on to calibrating and profiling a display.
+ For this reason, <span style="font-weight: bold;">dispcal</span>
+ offers a menu of adjustment modes, so that the user can
+ interactively and iteratively adjust the display controls to meet
+ the desired targets.<br>
+ <br>
+ &nbsp; 1) Black level (CRT: Brightness)<br>
+ &nbsp; 2) White point (Color temperature, R,G,B, Gain/Contrast)<br>
+ &nbsp; 3) White level (CRT: Gain/Contrast, LCD:
+ Brightness/Backlight)<br>
+ &nbsp; 4) Black point (R,G,B, Offset/Brightness)<br>
+ &nbsp; 5) Check all<br>
+ &nbsp; 6) Measure and set ambient for viewing condition adjustment<br>
+ &nbsp; 7) Continue on to calibration<br>
+ &nbsp; 8) Exit<br>
+ <br>
+ There are four basic adjustment modes. Normally one would proceed
+ through them in the order above, then perhaps repeat the first
+ adjustment, before checking the overall settings. The White point
+ and White level modes operate slightly differently, depending on
+ whether a white target point has been set using the <span
+ style="font-weight: bold;">-t -T</span> or <span
+ style="font-weight: bold;">-w</span> options, and on whether a
+ brightness target has been set using the <span style="font-weight:
+ bold;">-b</span> option.<br>
+ <br>
+ <br>
+ The first mode lets you adjust the black level of a CRT display.
+ Given the current white level, it calculates a value that should
+ produce a 1% display brightness if the black level is set correctly.
+ After doing some initial measurements, it will show the target
+ brightness value (in cd/m^2) on one line, and then underneath it
+ will show continuously updated readings from the display. The left
+ most character will switch from '\' to '/' or back again each time a
+ reading is updated. Some instruments can be quite slow in measuring
+ dark colors, and it's best to wait for a reading update before
+ changing the controls more than once. Underneath the target value is
+ displayed the current reading, and to the right of this is a '+',
+ '-' or '=' symbol, which gives a hint as to which way to adjust the
+ brightness control to improve the match to the target.<br>

+ <br>
+ Once happy with the adjustment, press space to go back to the menu.<br>
+ <br>
+ <br>
+ The second mode lets you adjust the color of the white point of the
+ display. If a target white point has been set, it will show the
+ target brightness value (in cd/m^2) on one line, together with the
+ target chromaticity co-ordinates for the white point, and then
+ underneath it will show continuously updated readings from the
+ display. The left most character will switch from '\' to '/' or back
+ again each time a reading is updated. Underneath the target
+ brightness value is displayed the current reading, and then the
+ current chromaticity co-ordinate values. To the right of this is the
+ current delta E of the white point from the target, and further to
+ the right are hints '+', '-' or '='&nbsp; as to which direction to
+ adjust the individual Red, Green and Blue gain settings to move the
+ white point in the direction of the target, and reduce the delta E.
+ If the symbol is doubled, then this channel will have the greatest
+ effect. If you do not have individual channel gain controls, then
+ try choosing amongst color temperature pre-sets, to find one with
+ the lowest delta E. Depending on the stability of the display, the
+ coarseness of the controls, and the repeatability of the instrument,
+ you may not be able to get a perfectly zero delta E.<br>

+ If you did not set a white point target, then the information shown

+ point to either the Daylight or Black Body locus (depending on
+ whether the <span style="font-weight: bold;">-T</span> flag was
+ set). The constantly updated values show the same thing, and the
+ Red, Green and Blue control hints show the direction to adjust the
+ controls to place the white point on the locus. The control that
+ will have the most direct effect on the color temperature will be
+ the Blue, while the Green will most directly move the white point
+ towards or away from the locus, thereby reducing the delta E of the
+ white point to the locus (but there is interaction).<br>

+ <br>
+ <br>
+ The third mode lets you adjust the brightness of white on the
+ display. If you set a target brightness using the <span

+ <br>
+ <br>
+ The fourth mode lets you adjust the color of the black point of the
+ display, if the display has Red, Green and Blue channel offset
+ controls. It will show the target 1% brightness value (in cd/m^2) on

+ <br>
+ The sixth selection <span style="font-weight: bold;">6)</span>
+ allows the reading of you ambient lighting conditions if your

+ style="font-weight: bold;">-a</span> option to compensate for your
+ viewing conditions in the subsequent calibration. See <a
+ href="dispcal.html#a">-a</a>.<br>
+ <br>
+ Once&nbsp; you're happy with the display set-up, you can either
+ proceed on to the rest of the calibration by selecting <span
+ style="font-weight: bold;">7)</span>, or exit and re-start by
+ selecting <span style="font-weight: bold;">8)</span>. You might
+ want to re-start if you want to change the calibration targets.<br>
+ <br>
+ <hr style="width: 100%; height: 2px;">
+ <h2>Other caveats:</h2>
+ NOTE that some <span style="font-weight: bold;">LCD</span> screens
+ behave a little strangely near their absolute white point, and may
+ therefore exhibit odd behavior at values just below white. It may be
+ advisable in such cases to set a brightness slightly less than the
+ maximum such a display is capable of.<br>
+ <br>
+ The program attempts to stop any screensaver or powersaver from
+ interfering with the measurements, but this may not be effective on
+ some systems, so it may be necessary to manually disable the
+ screensaver and/or powersaver before commencing the calibration with
+ a large number of patches.<br>
+ <br>
+ The calibration tables produced maintain the maximum level of
+ precision available on a system. If the display has VideoLUTs
+ available (Video Lookup Tables that the frame buffer values pass
+ through on their way to the display) and thier outputs are better
+ than 8 bits per component, then the resulting curves can reflect
+ this, although few current operating systems and/or display cards
+ actually support better than 8 bit per component output.<br>
+ <br>
+ If calibration curves are created for a display in which VideoLUTs
+ are not available, then the resulting calibration file will be
+ marked to indicate this, and a subsequent profile created with the
+ calibration will not have the calibration converted to the 'vcgt'
+ tag, since such a tag can't be loaded into the displays VideoLUTs.<br>
+ <br>
+ If communications break down with a USB connected instrument, you
+ may have to unplug it, and plug it in again to recover operation.<br>
+ <br>
+ Some systems (Apple OS X in particular) have a special set of user
+ interface controls ("Universal Access") that allows altering the
+ display in ways designed to assist visually impaired users, by
+ increasing contrast etc. This will interfere badly with any attempts
+ to calibrate or profile such a system, and must be turned off in
+ order to do so. Note that certain magic keyboard sequences can turn
+ this on by accident.<br>

- and vertical offset respectively. A value of 0.0 positions the
- window to the far left or top of the screen, a value of 0.5
- positions it in the center of the screen (the default), and 1.0
- positions it to the far right or bottom of the screen. If three

- parameter is a scale factor for the test window size. A value of 0.5
- for instance, would produce a half sized window. A value of 2.0 will
- produce a double size window. If four parameters are provided, then
- the last two set independent horizontal and vertical scaling
- factors. Note that the ho,vo,ss or ho,vo,hs,vs numbers must be
- specified as a single string (no space between the numbers and the
- comma). For example, to create a double sized test window at the top
- right of the screen, use <span style="font-weight: bold;">-P 1,0,2</span>
- . To create a window twice as wide as high: <span
- style="font-weight: bold;">-P 1,0,2,1</span>.<br>
- <br>
- <a name="F"></a> The <span style="font-weight: bold;">-F</span>
- flag causes the while screen behind the test window to be masked
- with black. This can aid black accuracy when measuring CRT displays
- or projectors.<br>
- <br>
- <a name="E"></a> The <span style="font-weight: bold;">-E</span>
- flag causes the test values to be scaled to the Video RGB encoding
- range of 16/255 to 235/255. If the calibration file provided using
- the <b>-k</b> or <b>-K</b> flag was created using video range
- encoding, then this option will be triggered automatically. This
- will also set quantization of 8 bits (see -Z flag below). If your
- video connection is better than 8 bits (ie. 10 or 12 bits), then you
- may wish to raise this default.<br>
- <br>
- <a name="Z"></a> <b>-Z nbits </b>Normally the target device values
- are floating point numbers that may get rounded and quantized in the
- process of printing them or reproducing them on the display device.
- If some of this quantization can be accounted for, it may improve
- the accuracy of the resulting profile, and the <span
- style="font-weight: bold;">Q</span> parameter allows this
- quantization to be specified. The parameter is the number of binary
- digits (bits) that the device values should be quantized to. An idea
- of the number of bits of precision that makes its way to your
- display can be obtained by using <a href="dispcal.html#R">dispcal
- -R</a> If Video encoding is selected (see -E flag above), then 8
- bits is selected by default. On systems using an VGA connection or
- Display Port with a graphics card with VideoLUT entries with greater

- then a higher bit depth is typically possible.<br>
- <br>
- <a name="n"></a><span style="font-weight: bold;">-n</span>: When
- running on a UNIX based system that used the X11 Windowing System, <b>dispread</b>
- normally selects the override redirect so that the test window will
- appear above any other windows on the display. On some systems this
- can interfere with window manager operation, and the <b>-n</b>
- option turns this behaviour off.<br>
- <br>
- <a name="J"></a> The -<span style="font-weight: bold;">J</span>
- option runs through the black and sensor relative calibration
- routines for the Xrite DTP92 and DTP94 instrument, the black level
- calibration for the Eye-One Display 1, and a CRT frequency
- calibration for the Eye-One Display 2. For the black calibration the
- instrument should be placed on an opaque, black surface, and any
- stray light should be avoided by placing something opaque over the
- instrument. If a Spectrolino is being used, then a white and black
- calibration will always be performed before the instrument can be
- placed on the display, unless the <a href="#N">-N</a> flag is used.
- Generally it is not necessary to do a calibration every time an
- instrument is used, just now and again. There is no point in
- doing&nbsp; a CRT frequency calibration, as this will be done
- automatically at the commencement of patch reading.<br>
- <br>
- <a name="N"></a> <span style="font-weight: bold;">-N</span> Any
- instrument that requires regular calibration will ask for
- calibration on initial start-up. Sometimes this can be awkward if
- the instrument is being mounted in some sort of measuring jig, or
- annoying if several sets of readings are being taken in quick
- succession. The -<span style="font-weight: bold;">N</span>
- suppresses this initial calibration if a valid and not timed out
- previous calibration is recorded in the instrument or on the host
- computer. It is advisable to only use this option on the second and
- subsequent measurements in a single session.<br>
- <br>
- <a name="H"></a> The -<span style="font-weight: bold;">H</span>
- option turns on high resolution spectral mode, if the instrument
- supports it. See <a href="instruments.html">Operation of particular
- instruments</a> for more details. This may give better accuracy
- for display measurements.<br>
- <br>
- <a name="w"></a>The <b>-w</b> flag disables the normalisation of
- the white patch value to 100.0, resulting in values that are in
- cd/m^2. This is mainly for diagnostic purposes.<br>
- <br>
- <a name="X1"></a> The -<span style="font-weight: bold;">X <span
- style="font-style: italic;">file.ccmx</span></span> option reads
- a <a href="File_Formats.html#.ccmx">Colorimeter Correction Matrix</a>
- from the given file, and applies it to the colorimeter instruments
- readings. This can improve a colorimeters accuracy for a particular
- type of display. A list of contributed <span style="font-weight:

- <br>
- <a name="X2"></a> The -<span style="font-weight: bold;">X <span
- style="font-style: italic;">file.ccss</span></span> option reads
- a <a href="File_Formats.html#.ccss">Colorimeter Calibration
- Spectral Sample</a> from the given file, and uses it to set the

- colorimeters that rely on sensor spectral sensitivity calibration
- information (ie. the X-Rite <span style="font-weight: bold;">i1d3</span>,
- or the DataColor <span style="font-weight: bold;">Spyder4 &amp;
- Spyder 5</span>).This can improve a colorimeters accuracy for a
- particular type of display.<br>
- <br>
- <a name="Q"></a> The <b>-Q</b> flag allows specifying a tristimulus
- observer, and is used to compute PCS (Profile Connection Space)
- tristimulus values from spectral readings or using a colorimeter
- that has CCSS capability. The following choices are available:<br>
- <b>&nbsp; 1931_2</b> selects the standard CIE 1931 2 degree
- observer. The default.<br>
- &nbsp; <b>1964_10</b> selects the standard CIE 1964 10 degree

- &nbsp; <b>shaw</b> selects the Shaw and Fairchild 1997 2 degree
- observer<br>
- &nbsp; <b>1964_10c</b> selects a version of the CIE 1964 10 degree
- observer that has been adjusted using a 3x3 matrix to better agree
- with the 1931 2 degree observer.<br>
- <br>
- <span style="font-weight: bold;">NOTE</span> that if you select
- anything other than the default 1931 2 degree observer, that the Y
- values will not be cd/m^2, due to the Y curve not being the CIE 1924
- photopic V(&#955;) luminosity function.<br>
- <br>
- <a name="I"></a> The -<span style="font-weight: bold;">I <span
- style="font-style: italic;">b|w</span></span> options invoke
- instrument black level, and display white level compensation
- (respectively). Instrument black level drift compensation attempts
- to combat instrument black calibration drift by using a display
- black test patch as a reference. If an instrument is not
- acclimatised sufficiently to the measurement conditions, changes in
- temperature can affect the black readings. Display white level drift
- compensation attempts to combat changes in display brightness as it
- warms up by measuring a white patch every so often, and using it to
- normalise all the other readings. If just instrument black drift
- compensation is needed, use <span style="font-weight: bold;">-Ib</span>.
- If just display white level compensation is needed, use <span
- style="font-weight: bold;">-Iw</span>. If both are needed, use <span
- style="font-weight: bold;">-Ibw</span> or <span
- style="font-weight: bold;">-Iwb</span>.<br>
- <br>
- <a name="YR"></a> The -<span style="font-weight: bold;">Y R:<i>rate</i></span>
- options overrides calibration of the instrument refresh rate. This
- may be useful if the instrument supports this function and the
- refresh rate cannot be accurately calibrated from the display
- itself.<br>
- <span style="font-weight: bold;">&nbsp;<br>
- </span><a name="YA"></a> The -<span style="font-weight: bold;">Y A</span>
- option uses a non-adaptive integration time emission measurement
- mode, if the instrument supports it, such as the Eye-One Pro,
- ColorMunki, i1d3 and K10. By default an adaptive integration time
- measurement mode will be used for emission measurements, but some
- instruments support a fixed integration time mode that can be used
- with display devices. This may give faster measurement times, but
- may also give less accurate low level readings.<br>
- <br>
- <a name="Yp"></a> The -<span style="font-weight: bold;">Y p</span>
- option skips asking the user to place the instrument on the display.
- Normally a grey patch is displayed, and then the user is asked to
- confirm that the instrument is in place, so that readings can
- commence. This flag disables that check. This may be useful in
- automating certain operations.<br>
- <span style="font-weight: bold;"><br>
- </span><a name="C"></a> The -<span style="font-weight: bold;">C</span>
- <span style="font-weight: bold;">"command" </span>option allows a
- method of relaying each test value to some other display than that
- on the system running dispread (for instance, a photo frame, PDA
- screen etc.), by causing the given command to be invoked to the
- shell, with six arguments. The first three arguments are the RGB
- test color as integers in the range 0 to 255, the second three
- parameters are the RGB test color as floating point numbers in the
- range 0.0 to 1.0. The script or tool should relay the given color to
- the screen in some manner (e.g. by generating a raster file of the
- given color and sending it to the display being profiled), before
- returning. Note that a test window will also be created on the
- system running dispread.<br>
- <br>
- <a name="M"></a> The -<span style="font-weight: bold;">M</span> <span
- style="font-weight: bold;">"command" </span>option allows a
- method of gathering each test value from some external source, such
- as an instrument that is not directly supported by Argyll. The given
- command is involked to the shell, with six arguments. The first
- three arguments are the RGB test color as integers in the range 0 to
- 255, the second three parameters are the RGB test color as floating
- point numbers in the range 0.0 to 1.0. The script or tool should
- create a file called <span style="font-weight: bold;">"command.meas</span>"
- that contains the XYZ values for the given RGB (or measured from the
- test window) in cd/m^2 as three numbers separated by spaces, before
- returning. If the command returns a non-zero return value, dispread
- will abort. Note that a test window will also be created on the
- system running dispread.<br>
- <br>
- <a name="x"></a> The <b>-x</b> flag causes dispread to expect
- values to be manually entered for each reading, rather than using an
- instrument to do the measurements.&nbsp; This mode is ideal if your
- instrument is not supported by Argyll. XYZ values should be entered.
- It is possible to navigate about the test values being measured, so
- as to do them in any order, as well as re-do values, in case of any
- mistakes.<br>
- <br>
- <a name="W"></a>The <b>-W</b> <span style="font-weight: bold;">n|h|x</span>
- parameter overrides the default serial communications flow control
- setting. The value <span style="font-weight: bold;">n</span> turns
- all flow control off, <span style="font-weight: bold;">h</span>
- sets hardware handshaking, and <span style="font-weight: bold;">x</span>
- sets Xon/Xoff handshaking. This commend may be useful in workaround
- serial communications issues with some systems and cables. <br>
- <br>
- <a name="D"></a>The <b>-D</b> flag causes communications and other
- instrument diagnostics to be printed to stdout. A level can be set
- between 1 .. 9, that may give progressively more verbose
- information, depending on the instrument. This can be useful in
- tracking down why an instrument can't connect.<br>
- <br>
- <a name="p1"></a> The final parameter on the command line is the
- base filename for the <a href="File_Formats.html#.ti1">.ti1</a>
- input file, and the <a href="File_Formats.html#.ti3">.ti3</a>
- output file. <b>dispread</b> will add the .ti1 and .ti3 extensions
- automatically.<br>
- <br>
- <span style="font-weight: bold;">NOTE</span> that on an X11 system,
- if the environment variable <span style="font-weight: bold;">ARGYLL_IGNORE_XRANDR1_2</span>
- is set (ie. set it to "yes"), then the presence of the XRandR 1.2
- extension will be ignored, and other extensions such as Xinerama and
- XF86VidMode extension will be used. This may be a way to work around
- buggy XRandR 1.2 implementations.<br>
- <br>
- <hr style="width: 100%; height: 2px;"><br>
- If a large number of patches is being read, the screensaver on many
- systems can interfere with the operation of dispread. It is
- therefore advisable in these cases to manually turn off the
- screensaver before commencing the measurements.<br>
- <br>
- If communications break down with a USB connected instrument, you
- may have to unplug it, and plug it in again to recover.<br>
- <br>
- Some systems (Apple OSX in particular) have a special set of user
- interface controls ("Universal Access") that allows altering the
- display in ways designed to assist visually impaired users, by
- increasing contrast etc. This will interfere badly with any attempts
- to calibrate or profile such a system, and must be turned off in
- order to do so. Note that certain magic keyboard sequences can turn
- this on by accident.<br>

+ positions it in the center of the screen (the default), and 1.0
+ positions it to the far right or bottom of the screen. If three
+ parameters are provided, then the <span style="font-weight: bold;">ss</span>
+ parameter is a scale factor for the test window size. A value of 0.5
+ for instance, would produce a half sized window. A value of 2.0 will
+ produce a double size window. If four parameters are provided, then
+ the last two set independent horizontal and vertical scaling
+ factors. Note that the ho,vo,ss or ho,vo,hs,vs numbers must be
+ specified as a single string (no space between the numbers and the
+ comma). For example, to create a double sized test window at the top
+ right of the screen, use <span style="font-weight: bold;">-P 1,0,2</span>
+ . To create a window twice as wide as high: <span
+ style="font-weight: bold;">-P 1,0,2,1</span>.<br>
+ <br>
+ <a name="F"></a> The <span style="font-weight: bold;">-F</span>
+ flag causes the while screen behind the test window to be masked
+ with black. This can aid black accuracy when measuring CRT displays
+ or projectors.<br>
+ <br>
+ <a name="E"></a> The <span style="font-weight: bold;">-E</span>
+ flag causes the test values to be scaled to the Video RGB encoding
+ range of 16/255 to 235/255. If the calibration file provided using
+ the <b>-k</b> or <b>-K</b> flag was created using video range
+ encoding, then this option will be triggered automatically. This
+ will also set quantization of 8 bits (see -Z flag below). If your
+ video connection is better than 8 bits (ie. 10 or 12 bits), then you
+ may wish to raise this default.<br>
+ <br>
+ <a name="Z"></a> <b>-Z nbits </b>Normally the target device values
+ are floating point numbers that may get rounded and quantized in the
+ process of printing them or reproducing them on the display device.
+ If some of this quantization can be accounted for, it may improve
+ the accuracy of the resulting profile, and the <span
+ style="font-weight: bold;">Q</span> parameter allows this
+ quantization to be specified. The parameter is the number of binary
+ digits (bits) that the device values should be quantized to. An idea
+ of the number of bits of precision that makes its way to your
+ display can be obtained by using <a href="dispcal.html#R">dispcal
+ -R</a> If Video encoding is selected (see -E flag above), then 8
+ bits is selected by default. On systems using an VGA connection or
+ Display Port with a graphics card with VideoLUT entries with greater
+ than 8 bits depth, or if using the MadVR rendered with dithering,
+ then a higher bit depth is typically possible.<br>
+ <br>
+ <a name="n"></a><span style="font-weight: bold;">-n</span>: When
+ running on a UNIX based system that used the X11 Windowing System, <b>dispread</b>
+ normally selects the override redirect so that the test window will
+ appear above any other windows on the display. On some systems this
+ can interfere with window manager operation, and the <b>-n</b>
+ option turns this behaviour off.<br>
+ <br>
+ <a name="J"></a> The -<span style="font-weight: bold;">J</span>
+ option runs through the black and sensor relative calibration
+ routines for the Xrite DTP92 and DTP94 instrument, the black level
+ calibration for the Eye-One Display 1, and a CRT frequency
+ calibration for the Eye-One Display 2. For the black calibration the
+ instrument should be placed on an opaque, black surface, and any
+ stray light should be avoided by placing something opaque over the
+ instrument. If a Spectrolino is being used, then a white and black
+ calibration will always be performed before the instrument can be
+ placed on the display, unless the <a href="#N">-N</a> flag is used.
+ Generally it is not necessary to do a calibration every time an
+ instrument is used, just now and again. There is no point in
+ doing&nbsp; a CRT frequency calibration, as this will be done
+ automatically at the commencement of patch reading.<br>
+ <br>
+ <a name="N"></a> <span style="font-weight: bold;">-N</span> Any
+ instrument that requires regular calibration will ask for
+ calibration on initial start-up. Sometimes this can be awkward if
+ the instrument is being mounted in some sort of measuring jig, or
+ annoying if several sets of readings are being taken in quick
+ succession. The -<span style="font-weight: bold;">N</span>
+ suppresses this initial calibration if a valid and not timed out
+ previous calibration is recorded in the instrument or on the host
+ computer. It is advisable to only use this option on the second and
+ subsequent measurements in a single session.<br>
+ <br>
+ <a name="H"></a> The -<span style="font-weight: bold;">H</span>
+ option turns on high resolution spectral mode, if the instrument
+ supports it. See <a href="instruments.html">Operation of particular
+ instruments</a> for more details. This may give better accuracy
+ for display measurements.<br>
+ <br>
+ <a name="w"></a>The <b>-w</b> flag disables the normalisation of
+ the white patch value to 100.0, resulting in values that are in
+ cd/m^2. This is mainly for diagnostic purposes.<br>
+ <br>
+ <a name="X1"></a> The -<span style="font-weight: bold;">X <span
+ style="font-style: italic;">file.ccmx</span></span> option reads
+ a <a href="File_Formats.html#.ccmx">Colorimeter Correction Matrix</a>
+ from the given file, and applies it to the colorimeter instruments
+ readings. This can improve a colorimeters accuracy for a particular
+ type of display. A list of contributed <span style="font-weight:
+ bold;">ccmx</span> files is <a href="ccmxs.html">here</a>.<br>
+ <br>
+ <a name="X2"></a> The -<span style="font-weight: bold;">X <span
+ style="font-style: italic;">file.ccss</span></span> option reads
+ a <a href="File_Formats.html#.ccss">Colorimeter Calibration
+ Spectral Sample</a> from the given file, and uses it to set the
+ colorimeter instruments calibration. This will only work with
+ colorimeters that rely on sensor spectral sensitivity calibration
+ information (ie. the X-Rite <span style="font-weight: bold;">i1d3</span>,
+ or the DataColor <span style="font-weight: bold;">Spyder4 &amp;
+ Spyder 5</span>).This can improve a colorimeters accuracy for a
+ particular type of display.<br>
+ <br>
+ <a name="Q"></a> The <b>-Q</b> flag allows specifying a tristimulus
+ observer, and is used to compute PCS (Profile Connection Space)
+ tristimulus values from spectral readings or using a colorimeter
+ that has CCSS capability. The following choices are available:<br>
+ <b>&nbsp; 1931_2</b> selects the standard CIE 1931 2 degree
+ observer. The default.<br>
+ &nbsp; <b>1964_10</b> selects the standard CIE 1964 10 degree
+ observer.<br>
+ &nbsp; <b>1955_2</b> selects the Stiles and Birch 1955 2 degree
+ observer<br>
+ &nbsp; <b>1978_2 </b>selects the Judd and Voss 1978 2 degree
+ observer<br>
+ &nbsp; <b>shaw</b> selects the Shaw and Fairchild 1997 2 degree
+ observer<br>
+ &nbsp; <b>1964_10c</b> selects a version of the CIE 1964 10 degree
+ observer that has been adjusted using a 3x3 matrix to better agree
+ with the 1931 2 degree observer.<br>
+ <br>
+ <span style="font-weight: bold;">NOTE</span> that if you select
+ anything other than the default 1931 2 degree observer, that the Y
+ values will not be cd/m^2, due to the Y curve not being the CIE 1924
+ photopic V(&#955;) luminosity function.<br>
+ <br>
+ <a name="I"></a> The -<span style="font-weight: bold;">I <span
+ style="font-style: italic;">b|w</span></span> options invoke
+ instrument black level, and display white level compensation
+ (respectively). Instrument black level drift compensation attempts
+ to combat instrument black calibration drift by using a display
+ black test patch as a reference. If an instrument is not
+ acclimatised sufficiently to the measurement conditions, changes in
+ temperature can affect the black readings. Display white level drift
+ compensation attempts to combat changes in display brightness as it
+ warms up by measuring a white patch every so often, and using it to
+ normalise all the other readings. If just instrument black drift
+ compensation is needed, use <span style="font-weight: bold;">-Ib</span>.
+ If just display white level compensation is needed, use <span
+ style="font-weight: bold;">-Iw</span>. If both are needed, use <span
+ style="font-weight: bold;">-Ibw</span> or <span
+ style="font-weight: bold;">-Iwb</span>.<br>
+ <br>
+ <a name="YR"></a> The -<span style="font-weight: bold;">Y R:<i>rate</i></span>
+ options overrides calibration of the instrument refresh rate. This
+ may be useful if the instrument supports this function and the
+ refresh rate cannot be accurately calibrated from the display
+ itself.<br>
+ <span style="font-weight: bold;">&nbsp;<br>
+ </span><a name="YA"></a> The -<span style="font-weight: bold;">Y A</span>
+ option uses a non-adaptive integration time emission measurement
+ mode, if the instrument supports it, such as the Eye-One Pro,
+ ColorMunki, i1d3 and K10. By default an adaptive integration time
+ measurement mode will be used for emission measurements, but some
+ instruments support a fixed integration time mode that can be used
+ with display devices. This may give faster measurement times, but
+ may also give less accurate low level readings.<br>
+ <br>
+ <a name="Yp"></a> The -<span style="font-weight: bold;">Y p</span>
+ option skips asking the user to place the instrument on the display.
+ Normally a grey patch is displayed, and then the user is asked to
+ confirm that the instrument is in place, so that readings can
+ commence. This flag disables that check. This may be useful in
+ automating certain operations.<br>
+ <span style="font-weight: bold;"><br>
+ </span><a name="C"></a> The -<span style="font-weight: bold;">C</span>
+ <span style="font-weight: bold;">"command" </span>option allows a
+ method of relaying each test value to some other display than that
+ on the system running dispread (for instance, a photo frame, PDA
+ screen etc.), by causing the given command to be invoked to the
+ shell, with six arguments. The first three arguments are the RGB
+ test color as integers in the range 0 to 255, the second three
+ parameters are the RGB test color as floating point numbers in the
+ range 0.0 to 1.0. The script or tool should relay the given color to
+ the screen in some manner (e.g. by generating a raster file of the
+ given color and sending it to the display being profiled), before
+ returning. Note that a test window will also be created on the
+ system running dispread.<br>
+ <br>
+ <a name="M"></a> The -<span style="font-weight: bold;">M</span> <span
+ style="font-weight: bold;">"command" </span>option allows a
+ method of gathering each test value from some external source, such
+ as an instrument that is not directly supported by Argyll. The given
+ command is involked to the shell, with six arguments. The first
+ three arguments are the RGB test color as integers in the range 0 to
+ 255, the second three parameters are the RGB test color as floating
+ point numbers in the range 0.0 to 1.0. The script or tool should
+ create a file called <span style="font-weight: bold;">"command.meas</span>"
+ that contains the XYZ values for the given RGB (or measured from the
+ test window) in cd/m^2 as three numbers separated by spaces, before
+ returning. If the command returns a non-zero return value, dispread
+ will abort. Note that a test window will also be created on the
+ system running dispread.<br>
+ <br>
+ <a name="x"></a> The <b>-x</b> flag causes dispread to expect
+ values to be manually entered for each reading, rather than using an
+ instrument to do the measurements.&nbsp; This mode is ideal if your
+ instrument is not supported by Argyll. XYZ values should be entered.
+ It is possible to navigate about the test values being measured, so
+ as to do them in any order, as well as re-do values, in case of any
+ mistakes.<br>
+ <br>
+ <a name="W"></a>The <b>-W</b> <span style="font-weight: bold;">n|h|x</span>
+ parameter overrides the default serial communications flow control
+ setting. The value <span style="font-weight: bold;">n</span> turns
+ all flow control off, <span style="font-weight: bold;">h</span>
+ sets hardware handshaking, and <span style="font-weight: bold;">x</span>
+ sets Xon/Xoff handshaking. This commend may be useful in workaround
+ serial communications issues with some systems and cables. <br>
+ <br>
+ <a name="D"></a>The <b>-D</b> flag causes communications and other
+ instrument diagnostics to be printed to stdout. A level can be set
+ between 1 .. 9, that may give progressively more verbose
+ information, depending on the instrument. This can be useful in
+ tracking down why an instrument can't connect.<br>
+ <br>
+ <a name="p1"></a> The final parameter on the command line is the
+ base filename for the <a href="File_Formats.html#.ti1">.ti1</a>
+ input file, and the <a href="File_Formats.html#.ti3">.ti3</a>
+ output file. <b>dispread</b> will add the .ti1 and .ti3 extensions
+ automatically.<br>
+ <br>
+ <span style="font-weight: bold;">NOTE</span> that on an X11 system,
+ if the environment variable <span style="font-weight: bold;">ARGYLL_IGNORE_XRANDR1_2</span>
+ is set (ie. set it to "yes"), then the presence of the XRandR 1.2
+ extension will be ignored, and other extensions such as Xinerama and
+ XF86VidMode extension will be used. This may be a way to work around
+ buggy XRandR 1.2 implementations.<br>
+ <br>
+ <hr style="width: 100%; height: 2px;"><br>
+ If a large number of patches is being read, the screensaver on many
+ systems can interfere with the operation of dispread. It is
+ therefore advisable in these cases to manually turn off the
+ screensaver before commencing the measurements.<br>
+ <br>
+ If communications break down with a USB connected instrument, you
+ may have to unplug it, and plug it in again to recover.<br>
+ <br>
+ Some systems (Apple OSX in particular) have a special set of user
+ interface controls ("Universal Access") that allows altering the
+ display in ways designed to assist visually impaired users, by
+ increasing contrast etc. This will interfere badly with any attempts
+ to calibrate or profile such a system, and must be turned off in
+ order to do so. Note that certain magic keyboard sequences can turn
+ this on by accident.<br>

- display if the display size is unknown.. The <span
- style="font-weight: bold;">ho</span> and <span
- style="font-weight: bold;">vo</span> values govern the horizontal
- and vertical offset respectively. A value of 0.0 positions the
- window to the far left or top of the screen, a value of 0.5
- positions it in the center of the screen (the default), and 1.0
- positions it to the far right or bottom of the screen. If three
- parameters are provided, then the <span style="font-weight: bold;">ss</span>
- parameter is a scale factor for the test window size. A value of 0.5
- for instance, would produce a half sized window. A value of 2.0 will
- produce a double size window. If four parameters are provided, then
- the last two set independent horizontal and vertical scaling
- factors. Note that the ho,vo,ss or ho,vo,hs,vs numbers must be
- specified as a single string (no space between the numbers and the
- comma). For example, to create a double sized test window at the top
- right of the screen, use <span style="font-weight: bold;">-P 1,0,2</span>

- <a name="F"></a> The <span style="font-weight: bold;">-F</span>

- <br>
- <a name="E"></a> The <span style="font-weight: bold;">-E</span>

- configured for Video encoding instead.<br>
- <br>

- <br>
- If the&nbsp;<a name="r"></a><span style="font-weight: bold;">-r</span>
- flag is set, then <span style="font-weight: bold;">dispwin</span>

- and registered with the operating system. For Linux X11 systems, the
- profile will be installed using the <a href="ucmm.html">ucmm</a>
- convention, and the X11 _ICC_PROFILE property in the root window,
- and also the the XrandR 1.2 X11 _ICC_PROFILE output property on
- systems that are running XrandR 1.2 or later. The latter is
- following this <a
- href="http://www.burtonini.com/computing/x-icc-profiles-spec-0.2.html">convention</a>
- for allowing applications to locate the display profile for a
- particular X11 display, and expands it to accomodate XrandR 1.2.
- Note that for X11 systems, the properties are not persistent, and
- will need to be loaded each time the X11 server is started (see the
- <a href="#L">-L</a> flag). To make sure that the profile calbration
- 'vcgt' tag gets loaded into the Graphics Card at system start,
- please read the guide <a href="dispprofloc.html">here</a>.<br>

- <a name="U"></a><span style="font-weight: bold;">-U</span>: The ICC
- profile specified as the final argument will be un-installed as the
- default operating system profile for the chosen display. The display
- calibration will remain unchanged.<br>
- <br>
- <a name="S"></a><span style="font-weight: bold;">-S</span> d: Some
- systems have more than one profile scope that an installed profile
- will apply to, and this parameter allows overriding the default user
- scope. On OS X, there is a choice of three scopes: <span
- style="font-weight: bold;">n</span>: for network scope, if people
- are sharing profiles over a network, <span style="font-weight:
- bold;">l</span>: local system scope, which installs the profile
- for all users of a system, and the default <span
- style="font-weight: bold;">u</span>, which covers just the user
- installing the profile. On Linux or Microsoft Vista, just the local
- system <span style="font-weight: bold;">l</span> and user <span
- style="font-weight: bold;">u</span> scope are available. Note that
- you may need to run dispwin with elevated privileges(sudo) to be
- able to successfully use network or local system scope. This option
- also applies to uninstalling a profile. Note that to install a user
- profile for the root account, you will have to login as root (sudo
- will not achieve this).<br>
- <br>
- <a name="L"></a> <span style="font-weight: bold;">-L</span>: This
- option fetches the current installed system profile for the chosen
- display, and sets the display to the calibration tag ('vcgt' tag, if
- any) in the profile. This is a convenient way of initializing the
- display on system startup from the installed display profile, if the
- system doesn't not do this automatically .<br>
- <br>
- <a name="X"></a> <span style="font-weight: bold;">-X</span>: Daemon
- mode (experimental). When running on a UNIX based system that used
- the X11 Windowing System, this option runs dispwin in a "daemon"
- mode where it monitors the given X11 server, waiting for any changes
- in monitors that may require loading a matching ICC profile (ie.
- such as re-configuring, plugging in a different monitor etc.)&nbsp;
- This only works if XRandR 1.2 is available on the server. By default
- dispwin runs silently, and will not terminate. If the <span
- style="font-weight: bold;">-v</span> option is given, it will emit
- messages to stdout to show what it is doing. When it is first
- invoked, it will load the installed profiles of all the screens of
- the given X11 server.<br>
- <br>
- <a name="D"></a>The <b>-D</b> flag causes diagnostics to be printed
- to stdout. A level can be set between 1 .. 9, that may give
- progressively more verbose information. This can be useful in
- tracking down why an operation fails.<br>
- <br>
- <a name="p1"></a> The final optional parameter on the command line
- is the name of an ICC profile that contains a Video LUT <span
- style="font-weight: bold;">vcgt</span> tag, or an Argyll <a
- href="cal_format.html">.cal</a> format display calibration. If
- this parameter is provided, then the selected display will be loaded
- with the given calibration. If the <span style="font-weight: bold;">-V</span>
- flag was given, then it is verified that this calibration is the
- currently loaded one.&nbsp; This may be useful in initializing a
- system to the current calibration on system startup, although a
- better way may be to install the profile (<span style="font-weight:
- bold;">-I</span> option), and then just use <span
- style="font-weight: bold;">-L</span>. Note that the vcgt tag
- interpretation within Argyll is consistent with that of the
- originators of the tag. Other ICC profile vcgt implementations may
- not be so consistent.<br>
- <br>
- <span style="font-weight: bold;">NOTE</span> that on an X11 system,
- if the environment variable <span style="font-weight: bold;">ARGYLL_IGNORE_XRANDR1_2</span>
- is set (ie. set it to "yes"), then the presence of the XRandR 1.2
- extension will be ignored, and other extensions such as Xinerama and
- XF86VidMode extension will be used. This may be a way to work around
- buggy XRandR 1.2 implementations.<br>
- <span style="font-weight: bold;"><br>
- NOTE</span> on MSWin systems that you will have to disable any
- other calibration installer program if you want to be able to
- control calibration using dispwin. Note also that there are other
- programs that will interfere with calibration loading, such as
- igfxpers.exe that gets installed with nVidia "Optimus" technology.<br>

+ <a name="P"></a> The <span style="font-weight: bold;">-P</span>

+ display if the display size is unknown.. The <span
+ style="font-weight: bold;">ho</span> and <span
+ style="font-weight: bold;">vo</span> values govern the horizontal
+ and vertical offset respectively. A value of 0.0 positions the

-<h2 style="text-decoration: underline; font-weight: bold;">How can I
-have confidence in the i1pro Driver ?<br>
-</h2>
-A question that has been asked is : "<span style="font-weight: bold;">You've
-written your own driver for the Eye-One Pro. How can I have confidence
-that the measurements are accurate, and will match those made with the
-original manufacturers driver </span>?"<br>
-<br>
-This is a quite reasonable question. The following attempts to answer
-it.<br>
-<h4 style="text-decoration: underline;">Why does Argyll use it's own
-i1pro driver ?</h4>
-Primarily because the Original Manufacturers Driver (OMD) isn't
-available for all the platforms that ArgyllCMS supports (Linux in
-particular). A side benefit is that it's possible to tweak many of the
-driver parameters for slightly better results and more flexibility. It
-has also helped in understanding the characteristics and limitations of
-such instruments.<br>
-<h4 style="text-decoration: underline;">Does it match the OMD ?</h4>
-In principle the behaviour should be very similar. While the Argyll
-driver has been written from scratch, it does use exactly the same
-calibration values from<br>
-inside the instrument, and attempts to use the calibration values and
-process the raw instrument readings in an equivalent manner to that of
-the OMD.<br>
-<br>
-But the proof of the pudding is in the measuring, so to actually verify
-this, the following experiment was conducted:<br>
-<br>
-The Argyll version used was V1.2.0<br>
-<br>
-The Macbeth 24 patch ColorChecker was used as a sample target. For each
-patch (and the calibration tile), the following steps were performed:<br>
-<br>
-1) Place the instrument on the calibration tile.<br>
-<br>
-2) Use Argyll spotread to calibrate the Argyll driver.<br>
-<br>
-3) Change drivers to the OMD.<br>
-<br>
-4) Use the OMD to calibrate the instrument.<br>
-<br>
-5) Move the instrument to the patch on the ColorChecker.<br>
-<br>
-6) Read the color using the OMD.<br>
-<br>
-7) Change the back to the Argyll driver.<br>
-<br>
-8) Using the calibration made in step 2), read the color using Argyll.<br>
-<br>
-Each calibration or reading was performed 15 seconds from the previous
-one, to put the instrument lamp in a repeatable state.<br>
-The instrument was kept in exactly the same position for calibration
-and patch measurement with the two drivers.<br>
-(The whole idea is to reduce all other sources of error, other than the
-driver itself.)<br>
-<br>
-This measurement was repeated just once for each patch + the
-calibration tile. This was done in one run, and the readings were not
-specially selected.<br>
-<h4 style="text-decoration: underline;">Results:</h4>
-The following D50 L*a*b* values were recorded for each measurement:<br>
-<br>
-A) &nbsp;&nbsp; The OMD internally calculated L*a*b* value<br>
-B) &nbsp;&nbsp; The L*a*b* value calculated by Argyll from the OMD
-spectral values.<br>
-C) &nbsp;&nbsp; The L*a*b* value calculated from the Argyll measured
-spectral values.<br>
-D) &nbsp;&nbsp; The L*a*b* value calculated from the Argyll
-Hi-Resolution mode measured spectral values.<br>
-<br>
-<span style="text-decoration: underline;">A is compare to B, to check
-that the spectral to standard observer calculations are equivalent.</span><br>
-<br>
-&nbsp;&nbsp;&nbsp; The result was an average Delta E (CIE76) of 0.006,
-with a maximum of 0.012.<br>
-<br>
-&nbsp;&nbsp;&nbsp; This shows that there is very close agreement in the
-way spectral values are converted to XYZ and L*a*b*.<br>
-<br>
-<span style="text-decoration: underline;">B is compared to C to check
-that the Argyll driver behaves the same as the OMD.</span><br>
-<br>
-&nbsp;&nbsp;&nbsp; The result was an average Delta E (CIE76) of 0.028,
-with a maximum of 0.051.<br>
-<br>
-&nbsp;&nbsp;&nbsp; This shows that the OMD and Argyll driver are in
-close agreement in spectral measurement.<br>
-&nbsp;&nbsp;&nbsp; This error is an order of magnitude smaller than
-uniformity induced errors typical in the media being measured.<br>
-<br>
-<span style="text-decoration: underline;">A is compared to C to check
-that the Argyll driver and spectral to XYZ differences don't compound.</span><br>
-<br>
-&nbsp;&nbsp;&nbsp; The result was an <span style="font-weight: bold;">average</span>
-Delta E (CIE76) of <span style="font-weight: bold;">0.026</span>, with
-a <span style="font-weight: bold;">maximum</span> of <span
- style="font-weight: bold;">0.048</span>.<br>
-<br>
-&nbsp;&nbsp;&nbsp; Rather than compounding, any spectral to XYZ
-differences tend to cancel
-out slightly. This is the <span style="font-weight: bold;">bottom line</span>
-experimental difference between
-the two drivers. The actual underlying difference may in fact be less
-than this, but it would be necessary to do multiple test runs to
-filter out experimental error.<br>
-<br>
-<span style="text-decoration: underline;">C is compare to D to check
-that the Argyll Hi-Resolution mode is behaving reasonably.</span><br>
-<br>
-&nbsp;&nbsp;&nbsp; The result was an average Delta E (CIE76) of 0.158,
-with a maximum of 0.353.<br>
-<br>
-&nbsp;&nbsp;&nbsp; Because the ColorChecker samples have relatively
-smooth reflectance spectra, it can be expected that<br>
-&nbsp;&nbsp;&nbsp; the normal and Hi-Res mode results should be fairly
-similar. And indeed, this is the case. The biggest<br>
-&nbsp;&nbsp;&nbsp; differences are for patches
-with the largest spectral transitions in them, which is to be expected
-as the<br>
-&nbsp;&nbsp;&nbsp; Hi-Res measurement more
-closely follows the spectral shape, while the differences for
-spectrally flat<br>
-&nbsp;&nbsp;&nbsp; patches is neglegable, since both can follow the
-spectral shape well.<br>
-<br>
-Example Yellow-Green Patch, Hi-Res &amp; Normal spectrum:<br>
-<img style="width: 709px; height: 259px;"
- alt="Yellow-Green patch, Hi-Res vs. Normal" src="YellowGreen.jpg"><br>
-<br>
-<h4 style="text-decoration: underline;">Conclusions:</h4>
-The experimental average difference of <span style="font-weight: bold;">0.026</span>
-Delta E76 shown above provides evidence that despite using a completely
-different instrument driver to that supplied with the instrument, the
-ArgyllCMS Eye-One pro measurement values have comparable accuracy, and
-can be relied upon to match measurements made using the original
-manufactures driver.<br>

What I've chosen to do with Argyll profiles, is to make all the AtoB
tables the same as colorimetric. This means that the conversion used
for the source profile is always colorimetric, and also means that
- the
- source gamut seen by the destination profile is the source
- colorspace
- gamut. This means that the gamut mapping is done solely in the BtoA
- tables,
- and that their task is to map the source colorspace gamut to the
- destination colorspace gamut. So to construct the perceptual and
- saturation intent mapping tables, a source profile or source gamut
- needs to be specified, so that a gamut mapping can be constructed.<br>

<br>
The advantages of this approach is that the behaviour is precisely
defined, a full range of gamut mapping options is available, and
compatibility with matrix profiles (which do not have gamut mapping
transforms) and other foreign profiles can be assured, by simply
- using
- such profiles as colorimetric sources. The main disadvantage is that
- the gamut mapping will only operate exactly as intended when the
- profile is linked with the source profile it was setup for. This is

Some non-Argyll profile have gamut mapping transforms in their
Perceptual and Saturation A2B tables, and this means that the
- apparent
- gamut of a source through these tables may be different to the
- actual
- device gamut. To accommodate using these profiles with CMM's (Color

- default
- use the gamut defined by the source profile perceptual table to

- the
- source saturation table to make the destination saturation table.

This approach has a number of drawbacks though. One is that the
- colors
- get gamut mapped twice. Gamut mapping is sometimes not very precise,
- and the geometry of the transforms may not cancel out, especially
- since
- different profile vendors may choose different algorithms in their
- gamut mapping. By "cancel out", I mean that even if you were linking
- the same source colorspace to the same destination colorspace, the
- gamut may be expanded (say) in the process of mapping to the PRMG,
- and
- then compressed again in mapping from the RMG to the device space,
- and
- these expansions and compressions may not quite match. Given that
- the
- PRMG is a relatively large gamut, larger than many real devices
- actual

The chief drawback, is that only one (non colorimetric) intent can
really be supported, that of saturation. <br>
<br>
The typically expected behavior of perceptual intent gamut mapping,

- to
- compress any areas of the source gamut that lie outside the
- destination
- gamut, but for areas that fall within the destination gamut, change
- them as little as possible, consistent with keeping smooth and

<br>
Typical behavior of a saturation intent, is (at least), to not only
compress out of gamut source colors to fit within the destination,
- but
- to expand any source boundary that falls within the destination
- gamut
- outwards match the destination gamut. Some practical saturation
- gamut
- mappings may go further than this, and expand a little beyond the

- <br>

+ including estimate its Ultra Violet content. A combination of direct
+ illumination readings and readings from a piece of paper having some
+ FWA content are used for this. (If the UV content is not needed, or
+ a suitable instrument is not available, then <a
+ href="spotread.html">spotread</a> should be used instead.)<br>

- <br>
- The second measurement needs a spectral instrument capable of

- is ideal, since cheap paper is typically whitened with large amounts
- of FWA. If the paper is thin (less than 160 gsm) then two or three
- sheets should be used to prevent any background showing through. If

- When used with a <span style="font-weight: bold;">DT20</span>, <span
- style="font-weight: bold;">DTP41</span>, <span
- style="font-weight: bold;">DTP51</span>, <span
- style="font-weight: bold;">Eye-One Pro<span style="font-weight:
- bold;"> </span></span>or <span style="font-weight: bold;">ColorMunki</span>
- strip reading instrument, chartread will first establish
- communications with the instrument, and then set it up ready to read
- the strips. The strips are labeled A to ZZ, and for each strip it
- will prompt:<br>
- <br>
- &nbsp;&nbsp;&nbsp; About to read strip XX&nbsp; :<br>
- <br>
- where XX is the strip label, and this is followed by the available
- options to navigate, read the strip, or finish. Note that the normal
- (forward) direction of strip reading is one that starts at the strip
- label.<br>
- <br>
- For the <span style="font-weight: bold;">DTP51</span> you should
- feed the strip into the instrument, and the microswitch will trigger
- the read.<br>
- <br>
- For the <span style="font-weight: bold;">DTP41</span> you should
- line the appropriate strip up in the machine, and press its button.<br>
- <br>
- For the <span style="font-weight: bold;">Eye-One Pro</span> you
- should set the guide to the appropriate strip, place the instrument
- <span style="text-decoration: underline;">ahead</span> of the first
- patch on blank paper, and then press and hold the instruments
- button. When you hear a beep from the computer, you can then move
- the instrument steadily over the patches, releasing the button after
- the instrument is past the last patch. Moving the instrument too
- fast or changing speeds may cause a mis-read, or a scan with few
- samples read per patch.<br>
- <br>
- For the <span style="font-weight: bold;">ColorMunki</span> with the
- default chart, the patches are the same width as the silver portion
- of body (white version), or the textured portion of the body (black
- version). Place aperture of the the instrument (located at its
- center) in the white space ahead of the first patch, and then press
- and hold the instruments button. When you hear a beep from the
- computer, you can then move the instrument steadily over the
- patches, releasing the button after the instrument is past the last
- patch. Moving the instrument too fast or changing speeds may cause a
- mis-read, or a scan with few samples read per patch. For the <span
- style="font-weight: bold;">high density</span> ColorMunki chart (<a
- href="printtarg.html#h">printtarg -h</a>), the patches are
- arranged so that three rows are exactly the width of the&nbsp; body
- of the instrument. If you are careful you can use this to guide the
- center of the instrument over each row, or you may prefer to use
- something like a plastic ruler to help guide the instrument.<br>
- <br>
- Using the <span style="font-weight: bold;">DTP20</span> or the <span
- style="font-weight: bold;">Eye-One Pro</span> or <span
- style="font-weight: bold;">ColorMunki</span> with a randomized
- chart layout, the strip may be scanned from either direction. If a
- randomized chart layout has not been used for the <span
- style="font-weight: bold;">Eye-One Pro</span> or <span
- style="font-weight: bold;">ColorMunki</span>, then the chart
- should only be read in the one direction (use <a
- href="chartread.html#B">chartread -B</a>).<br>
- <br>
- Note that you may have to check that system alert sounds are enabled
- and at a suitable volume to in order to hear the beep prompt. For
- the Eye-One Pro and ColorMunki, a second beep will sound after a
- successfully read strip, or a double beep will sound,&nbsp;
- indicating a failure or warning that needs attention. See also the
- note on Linux in <a href="Installing_Linux.html">installation</a>.<br>
- <br>
- If the strip is read successfully there will be a single "success"
- beep, and the line will be followed with:<br>
- <br>
- &nbsp;&nbsp;&nbsp; Ready to read strip&nbsp; XX&nbsp; : <br>
- &nbsp;&nbsp;&nbsp; Strip read OK<br>
- <br>
- If there is an error of some sort there will be a double "fail"
- beep, and a message will be issued, and you will be asked whether to
- abort the chart reading, or retry the<br>
- failed strip:<br>
- <br>
- &nbsp;&nbsp;&nbsp; Ready to read strip XX&nbsp; : <br>
- &nbsp;&nbsp;&nbsp; Strip read failed due to misread (Not enough
- patches)<br>
- <br>
- &nbsp;&nbsp;&nbsp; Hit Esc to give up, any other key to retry:<br>
- <br>
- If you are unable to successfully read a strip after several
- retries, you can skip that strip using the <span
- style="font-weight: bold;">'n'</span> key, and save<br>
- the chart readings without that strip.<br>
- <br>
- If the strip is read successfully, but the patches values don't seem
- to be what is expected, you will get a double "fail" beep&nbsp; and
- the following type of warning:<br>
- <br>
- &nbsp;&nbsp;&nbsp; Ready to read strip&nbsp; XX&nbsp; :<br>
- &nbsp;&nbsp;&nbsp; (Warning) Seem to have read strip&nbsp; YY&nbsp;
- rather than&nbsp; XX !<br>
- &nbsp;&nbsp;&nbsp; Hit Return to use it anyway, any other key to
- retry, Esc, ^C or Q to give up:<br>
- <br>
- This could be because you have accidentally read the wrong strip (a
- common mistake), or it could be that the device response is so
- different from what is expected that warning is erroneous, or you
- may get a lot of these sorts of warnings if you are accidentally
- reading the wrong chart. You may also get this sort of warning if
- you are not using bi-direction reading (chartread -B), and read the
- strip from the wrong end.<br>
- If you are absolutely sure you lined up the correct strip, then hit
- return, otherwise line the appropriate strip up again, and hit some
- other key (ie. space).<br>
- Erroneous warnings are less likely if a previous profile for a
- device was given to <span style="font-weight: bold;">targen</span>
- to set more accurate expectations.<br>
- <br>
- You may also see the following type of warning:<br>
- <br>
- &nbsp;&nbsp;&nbsp; Ready to read strip&nbsp; XX&nbsp; :<br>
- &nbsp;&nbsp;&nbsp; (Warning) Patch error YY.YYY (&gt;35 not good,
- &gt;95 bad)<br>
- &nbsp;&nbsp; There is at least one patch with an very unexpected
- response!<br>
- &nbsp;&nbsp;&nbsp; Hit Return to use it anyway, any other key to
- retry, Esc, ^C or Q to give up:<br>
- <br>
- Similar to the previous warning, this indicates that while the right
- strip appears to have been read, one of the patch readings is quite
- different to what is expected. This may indicate an error of some
- sort (ie. damaged test chart, or bad instrument positioning), or may
- be erroneous if the actual device response is quite different to the
- expectation. Erroneous warnings are less likely if a previous
- profile for a device was given to <span style="font-weight: bold;">targen</span>
- to set more accurate expectations.<br>
- <br>
- You can also navigate the next strip to be read using the <span
- style="font-weight: bold;">'f'</span> key to move forward and the
- <span style="font-weight: bold;">'b'</span> keys<span
- style="font-weight: bold;"></span><span style="font-weight: bold;"></span>
- to move backwards. The prompt will indicate whether this strip has
- already been read or not, or whether all strips have been read. You
- can also use <span style="font-weight: bold;">'n'</span> to move
- forward to the next unread strip. After each successful reading it
- will move forward to the next unread strip. When you are finished,
- use the <span style="font-weight: bold;">'d'</span> to indicate
- that you are done. You can choose to finish before all the strips
- are read, and the patches that have been read will be saved to the
- .ti3 file. This is useful if you are unable to read a particular
- strip successfully, or if you are unable to finish the chart in one
- session, and you can later <span style="text-decoration:
- underline;">resume</span> reading the chart by using the <span
- style="font-weight: bold;">chartread -r</span> flag. [You could
- resume reading the chart patch by patch using the <span
- style="font-weight: bold;">chartread -r -p</span> if you are
- unable to read a strip successfully.]<br>
- <br>
- When reading in patch by patch mode, there are a few additional
- navigation options, such as <span style="font-weight: bold;"><span
- style="font-weight: bold;">F</span></span> to move forward 10
- patches, <span style="font-weight: bold;">B</span> to move
- backwards 10 patches, and <span style="font-weight: bold;">g</span>
- to go to a specific patch.<br>
- <br>
- You can abort the whole process at any time by hitting Escape, and
- the readings will not be saved.<br>
- <br>
- <hr style="width: 100%; height: 2px;">
- <h3><a name="xy"></a>X-Y Table instruments</h3>
- When you are using an XY table type instrument, such as a Gretag <span
- style="font-weight: bold;">SpectroScan</span>, &nbsp;chartread
- will first establish communications with the instrument, and then
- set it up ready to read the chart. You will be prompted for each
- sheet with a message such as:<br>
- <br>
- &nbsp;&nbsp;&nbsp; Please make sure that the white reference is in
- slot 1, then<br>
- &nbsp;&nbsp;&nbsp; place sheet 1 of 4 on table, then<br>
- &nbsp;&nbsp;&nbsp; hit return to continue, Esc to give up<br>
- <br>
- After hitting return you will be prompted to line up three squares
- on the sheet, one at a time:<br>
- <br>
- &nbsp;&nbsp;&nbsp; Using the XY table controls, locate patch A1 with
- the sight,<br>
- &nbsp;&nbsp;&nbsp; then hit return to continue, Esc to give up<br>
- <br>
- On completing this, the instrument will commence reading each sheet.<br>

- instrument, or use the external values mode (<span
- style="font-weight: bold;">chartread -x</span>), chartread will
- first establish communications with the instrument, and then set it
- up ready to read the patches. The patches are typically labeled by
- column A to ZZ, and row 1-999. Each patch will prompt:<br>
- <br>
- &nbsp;&nbsp;&nbsp; Ready to read patch 'XX'&nbsp; :<br>
- <br>
- where XX is the patch label, and this is followed by the available
- options to navigate, read the strip, or finish.<br>
- <br>
- Place the instrument on the indicated patch, and trigger a reading
- using one of the available methods (typically using the instrument
- switch of pressing a key).<br>
- <br>
- There should be an audible prompt on a successful or failed reading.
- <br>
- <br>
- Note that you may have to check that system alert sounds are enabled
- and at a suitable volume to in order to hear the beep prompt. For
- the Eye-One Pro and ColorMunki, a second beep will sound after a
- successfully read strip, or a double beep will sound,&nbsp;
- indicating a failure or warning that needs attention. See also the
- note on Linux in <a href="Installing_Linux.html">installation</a>.<br>
- <br>
- If the patch is read successfully, the line will be completed with:<br>
- <br>
- &nbsp;&nbsp;&nbsp; Ready to read patch&nbsp; XX&nbsp; :<br>
- &nbsp;&nbsp;&nbsp; Patch read OK<br>
- <br>
- If there is an error of some sort, a message will be issued, and you
- will be asked whether to abort the chart reading, or retry the<br>
- failed patch:<br>
- <br>
- &nbsp;&nbsp;&nbsp; Ready to read patch XX&nbsp; : read_strip
- returned 'Strip misread' (Bad reading)<br>
- <br>
- &nbsp;&nbsp;&nbsp; Strip read failed due to misread<br>
- &nbsp;&nbsp;&nbsp; Hit Esc to give up, any other key to retry:<br>
- <br>
- You can navigate the next patch to be read using the <span
- style="font-weight: bold;">'f'</span> key to move forward and the
- <span style="font-weight: bold;">'b'</span> keys<span
- style="font-weight: bold;"></span><span style="font-weight: bold;"></span>
- to move backwards, while <span style="font-weight: bold;">'F'</span>
- and <span style="font-weight: bold;">'B'</span> will move forward
- and backwards by 10 patches. The prompt will indicate whether this
- patch has already been read or not, or whether all patches have been
- read. You can also use <span style="font-weight: bold;">'n'</span>

+ &nbsp;&nbsp;&nbsp; Ready to read patch 'XX'&nbsp; :<br>
+ <br>
+ where XX is the patch label, and this is followed by the available

- RRP, but the Photo package may be cheaper with discounting .<br>
- <br>
- <span style="font-weight: bold;">Limitations &amp; Features:</span><br>
- <br>
- Unlike the Eye-One Pro, the ColorMunki is only available in a U.V.
- Cut (ie. "Ultra Violet filtered") model. This means that it is not
- suitable for use with the&nbsp; Fluorescent Whitener Additive
- Compensation option in Argyll (see <a href="FWA.html">here</a> for
- a discussion about what FWA compensation is).<br>
- <br>
- Like the Eye-One Pro, this instrument does support the <a
- href="spotread.html#H">high resolution</a> spectral mode.<br>
- <br>
- <span style="font-weight: bold;">OS X and X-Rite drivers</span><br>
- <br>
- Please note the installation <a
- href="Installing_OSX.html#ColorMunki">instructions</a>.<br>
- <br>
- <span style="font-weight: bold;">Tips &amp; Tricks:<br>
- <br>
- </span>In handling the instrument when about to make a reading, be
- very careful not to accidentally press the switch - it is large and
- easily pressed by accident. A guide of some sort (ie. a plastic
- ruler) can help a lot in&nbsp; keeping the instrument over a line
- of&nbsp; patches. <br>
- <br>
- <span style="font-weight: bold;">Patch recognition:</span><br>
- <br>
- For the best chances of good patch recognition, the instrument
- should be drawn smoothly and not too rapidly over the strip. (This
- can be a little tricky due to the two small rubber feet on the
- bottom of the device that aid its spot reading guide.) If there is a
- misread, try slowing down slightly. Generally a higher quality set
- of readings will result if slower scans are used, since there will
- then be more samples averaged for each patch. <br>
- <br>
- In <a href="chartread.html">chartread</a>, the -<span
- style="font-weight: bold;">T ratio</span> argument modifies the
- patch consistency tolerance threshold for the ColorMunki. In
- recognizing patches in a strip, the instrument takes multiple
- readings as the strip is read, and then divide the readings up into
- each patch. It then check the consistency of the multiple readings
- corresponding to each patch, and reject the measurement if they are
- too inconsistent. For some media (ie. a coarser screens, fabric
- etc.) the default tolerance may be unreasonably tight, so the <span
- style="font-weight: bold;">-T ratio</span> argument can be used to
- modify this criteria. To loosen the tolerance, use a number greater
- than 1.0 (ie. 1.5, 2.0). <br>
- <br>
- Note that <a href="printtarg.html">printtarg</a> provides the <a
- href="printtarg.html#h">-h</a> option that allows the choice of
- two different patch row widths with ColorMunki test charts. [Some
- people have successfully used the i1Pro patch layout with the
- ColorMunki, by making a guide to keep it over the much narrower
- patchs.]<br>

- <br>
- <span style="font-weight: bold;">Special features:</span><br>
- <br>
- The <span style="font-weight: bold;">DTP20</span> has a couple of
- unique features that Argyll can take advantage of. One is that it
- can operate un-tethered (off line). A whole chart can be read
- un-tethered by first clearing any previous readings in the
- instrument, then reading the chart TID strip, before reading all the
- other strips. The instrument can then be connected up to <span
- style="font-weight: bold;">chartread</span>, which will recognize
- the chart, and download all the measurements.<br>
- If there is no chart in the instrument when chartread connects to
- it, then it will use the strip by strip tethered mode, just like the

- style="font-weight: bold;">spotread</span>, which will notice the

- readings.<br>
- <br>
- <span style="font-weight: bold;">Note</span> that tethered (on-line)
- strip reading will only work if the firmware in the device is
- version 1.03 or greater. You can check the firmware version by

- Chart printing:<br>
- <span style="font-weight: bold;"><br>
- </span></span>Because the DTP20 measures exact distances using the
- markings on its ruler, it's critical that the chart be printed out
- exactly the right size. If the chart gets re-sized at all in the
- process of printing it, the DTP20 is likely to fail in reading it.
- If you have a problem with this, you might want to increase the page
- margins using the <span style="font-weight: bold;">printtarg -m</span>

- style="font-weight: bold;">Operation:<br>
- <br>
- </span>When reading in tethered (on-line) mode, that the instrument
- takes <span style="font-weight: bold;">several seconds</span> to
- download the measurements after each strip, and that the indicator
- will be in "rainbow" mode while this occurs. <span
- style="text-decoration: underline;">Wait</span> until the
- indicator turns solid green again before starting to measure the
- next strip.<br>
- <br>
- To <span style="font-weight: bold;">reset</span> the instrument and
- clear any stored readings: press the button three times in quick
- succession. The indicator will turn solid blue. Then hold the button
- down until the instrument beeps and the indicator goes out. Release
- the button and the indicator should flash then return to solid green
- (ready).<br>
- <br>
- To <span style="font-weight: bold;">calibrate</span> the
- instrument, place it on its calibration tile, then press the button
- three times in quick succession.The indicator will turn solid blue.
- Click the button another three times in quick succession, and the
- indicator should turn yellow. Then hold the button down until the
- instrument beeps and the indicator goes out. Release the button and
- the instrument should flash and then turn solid green.<br>
- <br>
- If the chart is particularly <span style="font-weight: bold;">small</span>,
- the patches may end up printed very close to the edge of the chart,
- and therefore it may be difficult to confine your scan to the chart,
- and passing<br>
- the instrument over the edge of the chart may prevent it reading
- successfully. One way of working around this is to place the chart
- on a larger piece of paper of the same type.<br>
- <br>
- The <span style="font-weight: bold;">speed</span> of scan can be
- quite critical with this instrument. In particular, it doesn't work
- very well if the scan is too <span style="font-weight: bold;">slow</span>.
- You don't want to go too fast either, as this reduces the number of
- samples per patch.<br>

+ <br>
+ </span>The <span style="font-weight: bold;">ColorMunki</span> <span
+ style="font-weight: bold;">Design or Photo </span>from <a
+ href="http://www.xrite.com/">X-Rite</a>&nbsp; is currently
+ available in two different packages from the manufacturer. These
+ packages differ in what features the manufacturers software
+ provides, as well as cosmetic differences between the instrument
+ (white and black). This comparison <a
+ href="http://www.colormunki.com/product/show?page=2">chart</a>
+ illustrates the differences (Note that the ColorMunki Design comes
+ with <b>Pantone</b> libraries). Used with Argyll, there are no
+ differences in operation of a ColorMunki instrument, irrespective of
+ which package it came with. The ColorMunki Design has the lowest
+ RRP, but the Photo package may be cheaper with discounting .<br>
+ <br>
+ <span style="font-weight: bold;">Limitations &amp; Features:</span><br>
+ <br>
+ Unlike the Eye-One Pro, the ColorMunki is only available in a U.V.
+ Cut (ie. "Ultra Violet filtered") model. This means that it is not
+ suitable for use with the&nbsp; Fluorescent Whitener Additive
+ Compensation option in Argyll (see <a href="FWA.html">here</a> for
+ a discussion about what FWA compensation is).<br>
+ <br>
+ Like the Eye-One Pro, this instrument does support the <a
+ href="spotread.html#H">high resolution</a> spectral mode.<br>
+ <br>
+ <span style="font-weight: bold;">OS X and X-Rite drivers</span><br>
+ <br>
+ Please note the installation <a
+ href="Installing_OSX.html#ColorMunki">instructions</a>.<br>
+ <br>
+ <span style="font-weight: bold;">Tips &amp; Tricks:<br>
+ <br>
+ </span>In handling the instrument when about to make a reading, be
+ very careful not to accidentally press the switch - it is large and
+ easily pressed by accident. A guide of some sort (ie. a plastic
+ ruler) can help a lot in&nbsp; keeping the instrument over a line
+ of&nbsp; patches. <br>
+ <br>
+ <span style="font-weight: bold;">Patch recognition:</span><br>
+ <br>
+ For the best chances of good patch recognition, the instrument
+ should be drawn smoothly and not too rapidly over the strip. (This
+ can be a little tricky due to the two small rubber feet on the
+ bottom of the device that aid its spot reading guide.) If there is a
+ misread, try slowing down slightly. Generally a higher quality set
+ of readings will result if slower scans are used, since there will
+ then be more samples averaged for each patch. <br>
+ <br>
+ In <a href="chartread.html">chartread</a>, the -<span
+ style="font-weight: bold;">T ratio</span> argument modifies the
+ patch consistency tolerance threshold for the ColorMunki. In
+ recognizing patches in a strip, the instrument takes multiple
+ readings as the strip is read, and then divide the readings up into
+ each patch. It then check the consistency of the multiple readings
+ corresponding to each patch, and reject the measurement if they are
+ too inconsistent. For some media (ie. a coarser screens, fabric
+ etc.) the default tolerance may be unreasonably tight, so the <span
+ style="font-weight: bold;">-T ratio</span> argument can be used to
+ modify this criteria. To loosen the tolerance, use a number greater
+ than 1.0 (ie. 1.5, 2.0). <br>
+ <br>
+ Note that <a href="printtarg.html">printtarg</a> provides the <a
+ href="printtarg.html#h">-h</a> option that allows the choice of
+ two different patch row widths with ColorMunki test charts. [Some
+ people have successfully used the i1Pro patch layout with the
+ ColorMunki, by making a guide to keep it over the much narrower
+ patchs.]<br>

+ <br>
+ <span style="font-weight: bold;">Special features:</span><br>
+ <br>
+ The <span style="font-weight: bold;">DTP20</span> has a couple of
+ unique features that Argyll can take advantage of. One is that it
+ can operate un-tethered (off line). A whole chart can be read
+ un-tethered by first clearing any previous readings in the
+ instrument, then reading the chart TID strip, before reading all the
+ other strips. The instrument can then be connected up to <span
+ style="font-weight: bold;">chartread</span>, which will recognize
+ the chart, and download all the measurements.<br>
+ If there is no chart in the instrument when chartread connects to
+ it, then it will use the strip by strip tethered mode, just like the
+ other strip instruments. If the right number of spot readings are
+ present in the instrument, these will be used by <span
+ style="font-weight: bold;">chartread</span> too.<br>
+ <br>
+ Un-tethered spot measurements can also be read in using&nbsp; <span
+ style="font-weight: bold;">spotread</span>, which will notice the
+ stored readings, and offer to print them out, or they can be
+ ignored, and tethered readings taken. This will clear any saved spot

- </span>The <span style="font-weight: bold;">Eye-One Pro</span> from
- <a href="http://www.xrite.com/">X-Rite</a> (was Gretag MacBeth) is
- available in two packages from the manufacturer. These packages
- differ partly in what accessories come with the instrument, but
- primarily in what features the manufacturers software provides. This
- comparison <a
- href="http://www.xrite.com/product_overview.aspx?ID=812">chart</a>
- illustrates the differences. Used with Argyll, there are no
- differences in operation of an Eye-One Pro instrument, irrespective
- of which package it came with. The lowest cost package is the <a
- href="http://www.xrite.com/product_overview.aspx?ID=1461">i1 Basic
- Pro</a>.<br>
- <br>
- The EFI ES-1000 (which is a re-badged Eye-One Pro) is also reported
- to work with Argyll.<br>
- <br>
- Unless you know what you're doing, and have a very specific reason
- to buy an instrument fitted with a UV (Ultra Violet) filter, make
- sure that you buy an instrument without the filter. A UV filtered
- instrument can't deal intelligently with FWA (Fluorescent Whitener
- Additive) effects in paper. (Look <a href="FWA.html">here</a> for
- more information about FWA compensation.) Using FWA compensation you
- can make measurements using ISO 13655:2009 M0, M1 and M2 conditions.
- The M2 condition emulates a UV cut instrument.<br>
- <br>
- There have been four revisions of the Eye-One Pro, Rev. A, B, D and
- E (AKA Eye-One Pro2). The rev B, D and E are capable of sampling
- twice as fast as the Rev. A version of the instrument, and are also
- available with an ambient light reading capability.<br>
- <br>
- <span style="font-weight: bold;">NOTE</span> for those running on
- older versions of Linux with a Rev. D, there was a problem with the
- Linux USB stack that causes the instrument to stop working once it
- has been used. The only workaround is to unplug and replug the
- instrument in again, whereupon it can be used one time again. A fix
- for this problem was in the&nbsp; Linux 2.6.26 kernel release.<br>
- <br>
- See also <a href="i1proDriver.html">How can I have confidence in
- the i1pro Driver ?</a><br>
- <br>
- <span style="font-weight: bold;">Patch recognition:</span><br>
- <br>
- For the best chances of good patch recognition, the instrument
- should be drawn smoothly and not too rapidly over the strip. If
- there is a misread, try slowing down slightly. The Rev A and B.
- instruments have a slower sampling rate than the latter revision
- instruments, and hence must be used a bit more slowly. Generally a
- higher quality set of readings will result if slower scans are used,
- since there will then be more samples averaged for each patch.<br>
- <br>
- In <a href="chartread.html">chartread</a>, the -<span
- style="font-weight: bold;">T ratio</span> argument modifies the
- patch consistency tolerance threshold for the Eye-One Pro. In
- recognizing patches in a strip, the instrument takes multiple
- readings as the strip is read, and then divide the readings up into
- each patch. It then check the consistency of the multiple readings
- corresponding to each patch, and reject the measurement if they are
- too inconsistent. For some media (ie. a coarser screens, fabric
- etc.) the default tolerance may be unreasonably tight, so the <span
- style="font-weight: bold;">-T ratio</span> argument can be used to
- modify this criteria. To loosen the tolerance, use a number greater
- than 1.0 (ie. 1.5, 2.0). <span style="font-weight: bold;"></span><br>
- <br>
- <span style="font-weight: bold;">Special features:</span><br>
- <br>
- A feature unique to Argyll when used with the Eye-One Pro, is the
- high resolution spectral mode. This returns spectral measurements at
- 3.333 nm spacing, rather than the default 10nm spacing, and also
- extends the range of wavelengths very slightly. This high resolution
- may assist in giving better accuracy for "peaky" emissive sources
- such as illuminants and displays. The high resolution mode is
- selected by using the <span style="font-weight: bold;">-H</span>
- flag on the command line to <span style="font-weight: bold;">dispcal</span>,
- <span style="font-weight: bold;">dispread</span>, <span
- style="font-weight: bold;">chartread</span>, and <span
- style="font-weight: bold;">spotread</span>. It can also be toggled
- on and off within <span style="font-weight: bold;">spotread</span>
- using the <span style="font-weight: bold;">h</span> key.<br>
- <br>
- Note that while finer spectral resolution will worsen the signal to
- noise ratio of the individual spectral values, the signal to noise
- ratio of the resulting tri-stimulus color values will be identical
- to normal resolution mode, since the same overall integration is
- performed. <br>

+ able to re-circulate the tungsten back onto the filament properly.
+ It will then wait for the lamp to cool, and re-measure the drift.
+ These operations can take a few minutes, and it is advisable to let
+ the instrument cool off further after this operation, for 2 - 5
+ minutes, to allow it to return to normal operation conditions.<br>
+ <br>
