I know how create a DeviceLink, but i don't know how specify specific colors : By exemple : I got a RGB color gray( 128 128 128)and i want specify in the output device link, that this RGB color will be transform in a CMYK color cyan (100% 0 0 0 ). Is it possible ?
That means you need a profiler to create a ICC profile for you. Which can later be used by a profle linking tool. Typical that involves creation of a CGATS text file, which contains the colour association. But those CGATS files are most often created in a automatic way and are not recommended to create by hand by novel users.
In case you are still interested look at ArgyllCMS: http://www.argyllcms.comA other way, is to provide the table entries of the colour transform yourself and create a ICC profile. lcms has API's for doing this on the appropriate low level. Using such API for your purpose involves interpolating the colours in a programmatic way.
See the API in lcms2.h under cmsStageSampleCLut16bit() and in the manual. kind regards Kai-Uwe Behrmann --developing for colour management www.behrmann.name + www.oyranos.org
