LINKICC(1)

NAME
linkicc - little cms device link generator.

SYNOPSIS
linkicc [options] profiles

DESCRIPTION
lcms is a standalone CMM engine, which deals with the color management. It implements a fast transformation between ICC profiles. linkicc is a 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.

OPTIONS

-a NUM
    Observer adaptation state (abs.col. only), (0..1.0, float value) [defaults to 1.0].

-b  Black point compensation.

-c precision
    Precision (0=LowRes, 1=Normal, 2=Hi-res) [defaults to 1].

-d description
    Description text (quotes can be used).

-h NUM
    Show summary of options and examples (0=help, 1=Built-in profiles, 2=Examples, 3=Contact information)

-k inklimit
    Ink-limiting in % (CMYK only), (0..400.0, float value) [default 400.0].

-l  Use linearization curves (may affect accuracy).

-n gridpoints
    Alternate way to set precision, number of CLUT points.

-o profile
    Output devicelink profile [defaults to 'devicelink.icm'].

-r profileversion
    Profile version. (CAUTION: may change the profile implementation), (2.0..4.3, float value) [defaults to 4.3].

-t NUM
    Rendering intent
    0=Perceptual [default]
    1=Relative colorimetric
    2=Saturation
    3=Absolute colorimetric
    10=Perceptual preserving black ink
    11=Relative colorimetric preserving black ink
    12=Saturation preserving black ink
    13=Perceptual preserving black plane
    14=Relative colorimetric preserving black plane
    15=Saturation preserving black plane

-v verbosity
    Verbosity level, (0=None, 1=Normal, 2=High, 3=Very High) [defaults to 0].

-x  Creatively, guess deviceclass of resulting profile.

-y copyright
    Copyright notice (quotes can be used) ["No copyright, use freely"].

-8  Creates 8-bit devicelink.

BUILT-IN PROFILES
	*Lab2  -- D50-based v2 CIEL*a*b
	*Lab4  -- D50-based v4 CIEL*a*b
	*Lab   -- D50-based v4 CIEL*a*b
	*XYZ   -- CIE XYZ (PCS)
	*sRGB  -- sRGB color space
	*Gray22 - Monochrome of Gamma 2.2
	*Gray30 - Monochrome of Gamma 3.0
	*null   - Monochrome black for all input
	*Lin2222- CMYK linearization of gamma 2.2 on each channel

EXAMPLES
To create 'devicelink.icm' from a.icc to b.icc:
	linkicc a.icc b.icc

To create 'out.icc' from sRGB to cmyk.icc:
	linkicc -o out.icc *sRGB cmyk.icc

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

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

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

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

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