Create synthetic calibration file. The default is a linear calibration
synthcal [-options] basename
N i =
input, o = output, d = display (default)
-d col_comb choose colorant combination
from the following:
CMYK + Light CM
CMYK + Light CMK
CMYK + Red + Blue
CMYK + Orange + Green
CMYK + Light CMK + Light Light K
CMYK + Orange + Green + Light CM
CMYK + Light CM + Medium CM
-D colorant Add or delete colorant from
-?? to list known colorants)
o1,o2,o3, Set non-linear curve offset
s1,s2,s3, Set non-linear curve scale
-p p1,p2,p3, Set non-linear curve powers
outfile Base name
for output .cal file
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.
