Hi Terry, I think there is a way to do so. Can you send me the color data (LAB) you would like to create this synthetic CMYK profile and I will send you back the profile and workflow. Regards, Louis Dery louisdery at videotron.ca

While creating custom or synthetic RGB profiles is pretty straightforward, does anyone here know of any tools to create synthetic *CMYK* profiles?

I’m looking for something that will allow specifying of CMYK primaries and secondaries and a customizable TRC and then build an ICC profile.

The intent here is to build something like a “reference” or simulation profile for digital press and/or inkjet devices. I’ve gone through all the ISO 15339 CRPC profiles but none of them have the kind of gamut boundaries that I’m looking for..

Only tool that I can think of at the moment is the rather antiquated Custom CMYK tool in that’s been in Photoshop for a very long time…I’m not confident it will give me what I need.
