Usage

Overview

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
