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=H-res) [defaults to 1].

-d description

Description text (quotes can be used).

-h NUM

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

-k inklimit

In-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

-8

Creates -bit devicelink.

BUIL-IN PROFILES

        *Lab2 - D5-based v2 CIEL*a*b
        *Lab4 - D5-based v4 CIEL*a*b
        *Lab  - D5-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
        *Lin222- 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
