Summary

+Create synthetic calibration file. The default is a linear calibration +file.
+

Usage

+synthcal [-options] basename
+ -t +N            i = +input, o = output, d = display (default)
+ -d col_comb     choose colorant combination +from the following:
+                 +0: +Print grey
+                 +1: +Video grey
+                 +2: +Print RGB
+                 +3: +Video RGB
+                 +4: +CMYK
+                 +5: +CMY
+                 +6: +CMYK + Light CM
+                 +7: +CMYK + Light CMK
+                 +8: +CMYK + Red + Blue
+                 +9: +CMYK + Orange + Green
+                 +10: +CMYK + Light CMK + Light Light K
+                 +11: +CMYK + Orange + Green + Light CM
+                 +12: +CMYK + Light CM + Medium CM
+ -D colorant     Add or delete colorant from +combination:
+                 +(Use +-?? to list known colorants)
+ -o +o1,o2,o3,    Set non-linear curve offset +(default 0.0)
+ -s +s1,s2,s3,    Set non-linear curve scale +(default 1.0)
+ -p p1,p2,p3,    Set non-linear curve powers +(default 1.0)
+ outfile         Base name +for output .cal file
+

Comments
+

+This is the tool creates a calibration (.cal) +file that has a linear table +for each channel. This is useful in setting up a display for +evaluation, disabling printer calibration, testing, or to recover a +display that has a strange set of +Video LUTs loaded.
+
+The -t option +selects the type of device the calibration file is intended for. +Default is display.
+
+The -d option +selects the device colorspace. The default for input and display is Video RGB, while the default for output is CMYK.
+
+ The -D parameter modifies the colorspace set +by -d by allowing individual +colorants to be added or subtracted from the colorspace.
+
+Optionally it can be used to create a non-linear calibration file, +useful for diagnostics. Each of the device channel curves can be +given a gamma (power curve) shape, scaled to a maximum other than +1.0, and offset from a value other than 0.0.
