a .ti1 file. It output both a + PostScript/EPS/TIFF file, and a .ti2 file containing the device test + values together with the layout information needed to identify the + patch location. This module can also generate the image recognition + templates needed to read the print targets in using a scanner.<br> + <br> + <a name="v"></a> The <b>-v</b> flag turns on verbose mode. Prints + information about how many patches there are in a row, how many + patches in a set, and how many pages will be generated. Good + for figuring out what the magic number of patches should be for a + particular page size.<br> + <br> + <a name="i"></a> The <b>-i</b> parameter should be used to tell + printtarg which instrument it should lay the patches out for. Each + instrument has a slightly different requirement, and will lead to a + different number of patches ending up on a particular page size. For + a generic type of chart, try <span style="font-weight: bold;">SS</span>.<br> + <br> + <a name="a"></a><a name="A"></a> <span style="font-weight: bold;">-a, +-A: + + + </span>Normally, <b>printtarg</b> prints test patches that are the + minimum size that can be reliably and accurately read by the + instrument. For some media, it might be desirable to use test + patches that are larger than this minimum (e.g. if the media has + poor registration, gets physically distorted in the print production + process, or if it has a coarse screen, and there are few samples per + patch), and the <span style="font-weight: bold;">-a</span> flag + should be given an argument greater than 1.0 to increase the patch + length, patch width, and spacer size between patches, if it is + appropriate for the type of instrument. A value of 1.5 would make + the patch 50% larger for instance. For the strip reading instruments + the patch is made longer, the strip spacing remaining the same, + while for XY scanning instruments, both the width and height will be + increased. If a value less than 1.0 is given as an argument, then + the patches will be made smaller. For instance, using the + SpectroScan instrument it is possible to reduce the test patches to + 6mm rather than the default 7mm by supplying an argument of 0.857. + Note that this make lining up of the scan head very critical, and + increases the amount of bleed through from adjacent squares. For an + instrument that needs color spacers between patches, <span + style="font-weight: bold;">-a scale</span> also scales the spacer + length. For some situations, this may be insufficient, and the <span + style="font-weight: bold;"> -A scale</span> option can be used to + additionally scale the spacer length.<br> + Note that the for the <span style="font-weight: bold;">DTP20</span> + only <span style="font-weight: bold;">-a </span>values of 1.0, + 1.08, 1.54, 1.92, 2.0 and that the patch width will be made no + smaller than its length.<br> + <br> + <a name="h"></a> Normally, <b>printtarg</b> creates a regular grid + of test patches, but for instruments that support arbitrary X, Y + addressing (such as the SpectroScan). For the <span + style="font-weight: bold;">SpectroScan</span> it can also create a + chart using regular hexagonal patches, allowing more patches to be + fitted into a single sheet if the <span style="font-weight: bold;">-h</span> + flag is used. For the <span style="font-weight: bold;">ColorMunki</span> + instrument, <span style="font-weight: bold;">-h</span> doubles the + normal number of patches is printed by halving the row width. The + patches are also staggered to improve the detection of a poor scan.<br> + <br> + <a name="r"></a> Normally, <b>printtarg</b> randomizes the patch + locations, which helps strip reading instruments detect patch + boundaries and the direction the strip was read in, as well as being + able to detect incorrect strips being fed into strip reading + instruments, and also assists in randomizing any systematic printing + errors introduced into the test chart due to print engine + unevenness, inkjet banding, or printing press ink key settings etc. + The <b>-r</b> flag turns this off, and lays the test squares out in + the order the values appear in, in the .ti1 file. Note that if you + turn this off you probably want to <a href="chartread.html#B">disable + + + bi-directional</a> strip reading in instruments such as the i1pro.<br> + <br> + <a name="s"></a> The <b>-s</b> flag does two things. One is that it + causes printtarg to output a chart recognition file (<a + href="File_Formats.html#.cht">.cht</a>) so that <a + href="scanin.html"> scanin</a> can recognize the chart, and + convert rasterized patches into patch values, and the second is that + is expands the size of the leading row of patches by 50%, to help + make sure that each sheet can be oriented correctly by <a + href="scanin.html"> scanin</a>. <a name="S"></a>If <b>-S</b> is + used rather than <b>-s</b>, then the recognition chart will be + created, but the leading row will be the same size as all the other + rows.<br> + <br> + <a name="c"></a> For strip reading instruments, the contrast with + the spacers is important in ensuring that a reading will be + successful. Normally <span style="font-weight: bold;">printtarg</span> + ensures this by printing optimally contrasting colored spacers + between each measurement patch. The <b>-c</b> flag is therefore the + default behaviour. <a name="b"></a>If the <b>-b</b> flag is used, + then contrasting neutral colored spacers will be used, but these + generally work less reliably than colored spacers. <a name="n"></a>The + + <b>-n</b> flag will cause spacers to be omitted, which may still + work with smaller numbers of test values when the patch selection is + randomized, but won't work successfully when a large number of test + points is being used (>200), or when the patches are not + randomized in location.<br> + <br> + <a name="f"></a><b>-f</b>: When creating a test chart for more than + CMYK inks, a PostScript file normally contains color settings that + use the PostScript level 3 "Device N" color specifications. Such + color specifications have a "fallback" color, for PostScript + interpreters that don't handle Device N specifications. Such + fallback colors are normally set to a grayscale estimate of the + patch color, so that it is possible to tell if the PostScript + interpreter is not rendering the Device N values correctly. <a + name="f"></a>The <b>-f</b> flag, causes the fallback color to be + a color estimate of the Device N test patch color, which is useful + for diagnostic purposes.<br> + <br> + <a name="e"></a> The <b>-e</b> flag gives EPS output, rather than + PostScript, allowing the charts to be included in other + applications. Because EPS disallows the showpage command, multiple + EPS files will result for a multi-page test chart, each one having a + two digit number sequence in it's name, so if the input file name is + <span style="font-weight: bold;">chart</span>, then file <span + style="font-weight: bold;">chart.ti1</span> will be read, and file + <span style="font-weight: bold;">chart.ti2</span> written, together + with <span style="font-weight: bold;">chart.eps</span> if there is + only one page, or <span style="font-weight: bold;">chart_01.eps</span>, + <span style="font-weight: bold;">chart_02.eps</span>, etc. if there + is more than one page.<br> + <br> + <a name="t"></a><a name="T"></a><span style="font-weight: bold;">-t + [res], -T [res]</span> The <b>-t</b> flag gives TIFF raster + output rather than PostScript, allowing the charts to be printed to + systems that do not accept PostScript input. Because few systems + understand multi-page TIFF files, multiple TIFF files will result + for a multi-page test chart, each one having a two digit number + sequence in it's name, so if the input file name is <span + style="font-weight: bold;">chart</span>, then file <span + style="font-weight: bold;">chart.ti1</span> will be read, and file + <span style="font-weight: bold;">chart.ti2</span> written, together + with <span style="font-weight: bold;">chart.eps</span> if there is + only one page, or <span style="font-weight: bold;">chart_01.tif</span>, + <span style="font-weight: bold;">chart_02.tif</span>, etc. if there + is more than one page. By default the resolution of the chart will + be 100 Dots Per Inch (DPI), but this can be changed by providing an + optional DPI argument after the <span style="font-weight: bold;">-t</span> + or <span style="font-weight: bold;">-T</span> flag. If the <span + style="font-weight: bold;">-t</span> flag is used, than an 8 bit + per component TIFF file will be created. If the <span + style="font-weight: bold;">-T</span> flag is used, then a 16 bit + per component TIFF file will be created.<br> + <br> + <a name="C"></a><span style="font-weight: bold;">-C:</span> Normally + the TIFF files created will be compressed using LZW compression to + save space. Some systems may not support this compression, so it can + be disabled by using the <span style="font-weight: bold;">-C</span> + flag.<br> + <br> + <a name="N"></a><span style="font-weight: bold;">-N:</span> When + creating TIFF files with more than 4 colorants, the normal Separated + mode is used. Some systems don't cope well with extra colorants + presented in this manner, and the <span style="font-weight: bold;">-N</span> + flag causes all the channels greater than 4 to be labelled as + "Alpha" channels, which may be more palatable.<br> + <br> + <a name="D"></a><span style="font-weight: bold;">-D:</span> When + creating TIFF files with 8 bit output, dither the values to give + effective 16 bit precision. Note this is applied after any + quantization of the test values (see <a href="#Q">-Q</a>). Note + that this might interfere (i.e. give alias/moire patterns) in + printed output if the printer uses screening that happens to clash. + Note also that dithering is effectively linearly interpolating + between the 8 bit values using spatial averaging, and that therefore + the device response may also be a linear interpolation between its 8 + bit output values, adding no effective extra precision to the device + measurement. <br> + <br> + <a name="Q"></a><span style="font-weight: bold;">-Q:</span> 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 printing or 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. In many systems the right value would be 8 bits. Note + that if 8 bit TIFF<span style="font-weight: bold;"></span> output is + selected (<span style="font-weight: bold;">-t</span>) without + dithering (no <span style="font-weight: bold;">-D) </span>that the + values will by default be quantized to 8 bits, and that if 16 bit + TIFF<span style="font-weight: bold;"></span> output is selected (<span + style="font-weight: bold;">-T</span>) or 8 bit TIFF with dithering + (<span style="font-weight: bold;">-D) </span>that the values will + by default be quantized to 16 bits.<br> + <br> + <a name="K"></a> The <b>-K file.cal</b> parameter specifies a + printer calibration file created by <a href="printcal.html">printcal</a>, + and the supplied calibration curves will be applied to the test + patch values. This allows profiling of a printing system that + doesn't natively support calibration. The calibration curves will + also be included in the resulting .ti2 file, so that they can be + passed through to .ti3 file and ICC profile, to allow accurate + computation of ink limits.<br> + <br> + <a name="I"></a> The <b>-I file.cal</b> parameter specifies a + printer calibration file created by <a href="printcal.html">printcal</a>, + and the calibration curves will be included in the included in the + resulting .ti2 file, so that they can be passed through to .ti3 file + and ICC profile, to allow accurate computation of ink limits. The + calibration <span style="font-weight: bold;">is not applied</span> + to the test patch values, but is assumed to be applied somewhere + else in the printing workflow when printing the profile test chart.<br> + <br> + <a name="R"></a> The <b>-R</b> parameter allows setting the random + layout seed. Normally the seed is chosen at random, but sometimes it + is useful to be able to generate a chart with the same layout, so a + specific seed can be specified this way. The seed (ID) used to + generate a chart is recorded in the .ti2 file, and is also in the + label printed on the right hand side of each chart.<br> + <br> + <a name="x"></a> The <b>-x</b> parameter allows specifying the + labelling sequence used for strips (e.g. the X axis of the chart). + By default this will be a character sequence A, B, C .. Z. AA, AB, + AC .. ZZ, but this can be changed by specifying an alternate + labelling sequence pattern. The pattern specifies the labelling + sequence as follows: First comes the definition of the symbols for + each digit location, least significant to most significant, each + digit separated by the ',' character. Note that space is a valid + character. The number of definitions declares the maximum number of + digits. For example, for a 2 digit numerical sequence: "0123456789, + 123456789" would define 0..99 with the most significant digit + suppressed when it is 0 (because it uses a space rather than 0). + Ranges can be used for brevity: "0-9, 1-9". As a special case, the + '@' character can be used to instead of '0' to indicate suppression + of the leading zero: "0-9,@-9". Leading ' ' characters in the + resulting generated sequence are omitted. Optionally following this + and delimited by a ';' character, are the definitions of valid + segments of the index sequence. For instance, to define the index + range to be 1..19, 30..39 one could use the pattern "0-9, + 1-9;1-19,30-39". Of course most of the time an alphabetic sequence + will be wanted, to distinguish it from the numerical sequence used + to number the patches in a strip. For a sequence A, B, C .. AA, AB, + AC etc. (the default used in Argyll), the following patter would be + used: "A-Z, A-Z". For a some ECI2002R charts that skip columns Y and + Z, and use a leading numeric digits for addressing strips over 26, + the following might be used: "A-Z, 2-9;A-X,2A-9Z".<br> + <br> + <a name="y"></a> The <b>-y</b> parameter allows specifying the + labelling sequence used for patches (e.g. the Y axis of the chart). + By default this will be a number sequence 1, 2, ..10, 11, ... 999, + but this can be changed by specifying an alternate labelling + sequence pattern. See the above description for the labelling + sequence encoding.<br> + <br> + <span style="font-weight: bold;">NOTE</span> that the pattern chosen + for the X and Y axes of the chart must be distinguishable, e.g. if + they are both numbers or both letters then reading the chart will + fail.<br> + <br> + <a name="w"></a> The <b>-w</b> parameter changes how a white + colorspace test chart (ie. Additive Grey monochrome) will be + represented in the Postscript or TIFF output. The default is to use + the DeviceGray representation (<span style="font-weight: bold;">-wg</span>), + + but Device RGB can also be used, where the R, G &B values are + all set to the same value (<span style="font-weight: bold;">-wr</span>), + + a <span style="font-weight: bold;">White</span> separation color + can be specified (<span style="font-weight: bold;">-ws</span>), or a + DeviceN <span style="font-weight: bold;">White</span> color can be + used (<span style="font-weight: bold;">-wn</span>).<br> + <br> + <a name="k"></a> The <b>-k</b> parameter changes how a black + colorspace test chart (ie. Subtractive Grey monochrome ) will be + represented in the Postscript or TIFF output. The default is to use + the DeviceGray representation (<span style="font-weight: bold;">-kg</span>), +but +Device +CMYK +can +also + + + be used, where the CMY values are zero, and just the K channel is + used (<span style="font-weight: bold;">-kc</span>), a <span + style="font-weight: bold;">Black</span> separation color can be + specified (<span style="font-weight: bold;">-ks</span>), or a + DeviceN <span style="font-weight: bold;">Black</span> color can be + used (<span style="font-weight: bold;">-kn</span>).<br> + <br> + <a name="o"></a> The <b>-o</b> parameter changes how a CMY + colorspace test chart will be represented in the Postscript or TIFF + output. The default is to use the DeviceCMYK representation (<span + style="font-weight: bold;">-ok</span>) where the K value is always + zero, or inverted Device RGB (<span style="font-weight: bold;">-or</span>), + or as a 3 channel DeviceN colorsoace can be used (<span + style="font-weight: bold;">-on</span>).<br> + <br> + <a name="m"></a> The <b>-m</b> parameter sets the page margin for + all sides. If the printer has print margins larger than the default + assumed by <span style="font-weight: bold;">printtarg,</span> then + critical parts of the test chart may be cropped or scaled, and not + printed properly.<span style="font-weight: bold;"></span> Increasing + the margin from the default of 6 mm to 10 or 15 mm, may alleviate + this problem. (Note that the number of patches per page may be + reduced as a consequence.) Decreasing the margin below 6 mm may be + possible for printers that have smaller or no margins, increasing + the number of patches possible on each page. A TIFF chart raster + will be the size of the paper minus the margin, so that it can be + placed on a page that size without cropping or inadvertent scaling.<br> + <br> + <a name="M"></a> The <b>-M</b> parameter sets the page margin for + all sides the same as <span style="font-weight: bold;"><span + style="font-weight: bold;">-m</span></span>, but for a TIFF + chart the margin will be <span style="font-weight: bold;">included</span> + in the raster, meaning that the TIFF will have to be printed + right to the edge of the paper, or on paper larger than the raster + size. (Having the raster be the full page size may be useful in + certain situations.)<br> + <br> + <a name="P"></a> The <b>-P</b> flag disables any normal limiting of + strip length that would normally be imposed due to guide or + instrument limitations. There is still an upper limit of around 500 + patches or 2Meters though.

Limitations of the instrument may + limit the maximum number of patches in a strip. For SpectroScan, a + size of A4 or Letter (or smaller) should be used. Useful + combinations of number of patches and paper size are listed <a + href="targen.html#Table">here</a>. The printed parts of the chart + will be the size of paper minus the page margin.
