icclink - little cms device link generator.


icclink [options] <profiles>


lcms is a standalone CMM engine, which deals with the color management. It implements a fast transformation between ICC profiles. icclink is little cms device link generator.

Links two or more profiles into a single devicelink profile. Colorspaces must be paired except Lab/XYZ, that can be interchanged.


-8 Creates 8-bit devicelink.
-b Black point compensation.
-c <0,1,2,3>
 Precission (0=LowRes, 1=Normal, 2=Hi-res). [defaults to 1]
-d description
 Description text (quotes can be used).
-h <0,1,2,3>
 Show summary of options and examples.
-i profile
 Input profile (defaults to sRGB).
-k <0..400>
 Ink-limiting in % (CMYK only)
-o profile
 Output devicelink profile. [defaults to ’devicelink.icm’]
-t <0,1,2,3>
 Intent (0=Perceptual, 1=Colorimetric, 2=Saturation, 3=Absolute).
-x Creatively, guess deviceclass of resulting profile.
Built-in profiles:         *Lab -- D50-based CIEL*a*b (PCS)         *XYZ -- CIE XYZ (PCS)         *sRGB -- sRGB color space         *Gray22- Monochrome of Gamma 2.2         *Lin2222- CMYK linearization of gamma 2.2 on each channel


To create ’devicelink.icm’ from a.icc to b.icc:         icclink a.icc b.icc

To create ’out.icc’ from sRGB to cmyk.icc:         icclink -o out.icc *sRGB cmyk.icc

To create a sRGB input profile working in Lab:         icclink -x -o sRGBLab.icc *sRGB *Lab

To create a XYZ -> sRGB output profile:         icclink -x -o sRGBLab.icc *XYZ *sRGB

To create a abstract profile doing softproof for cmyk.icc:         icclink -t1 -x -o softproof.icc *Lab cmyk.icc cmyk.icc *Lab

To create a ’grayer’ sRGB input profile:         icclink -x -o grayer.icc *sRGB gray.icc gray.icc *Lab

To embed ink limiting into a cmyk output profile:         icclink -x -o cmyklimited.icc -k 250 cmyk.icc *Lab
