is it possible to use LCMS to create an ICC Profile with 5 channels
based on a default CMYK ICC-Profile?
What I try to do is:
1. Open an ICC-Profile (CMYK based)
2. modifiy this ICC-Profile by adding 1 additional channel. The CMYK
channels should be mapped to the first four channels with the same values.
The 5-th channel should contain for example a linear function from 0 to 1.
3. Save this modified profile as an ICC-Profile based on 5 channels.
All Ideas how to solve this problem are welcome.
Thanks a lot,
