Depending on how critical your application is here you may be able to get somewhere near using ArgyllCMS's fakeread utility, and generating a CMY profile based upon your CMYK profile. The process will involve generating a CMY target (.ti1 file) and "massaging" it in a spreadsheet so each CMY value is promoted to CMYK, and the K value set to zero. You can then read XYZ Values for each CMY combination in the target from your CMYK profile, using fakeread. More "massaging" is then needed on the resulting .ti3 file to remove the extraneous K column from the data. The .ti3 file now contains CMY values and their corresponding values in XYZ space, according to your CMYK profile, from which you can build a CMY profile. You can then use that CMY profile in conjunction with TYPE_CMY_16 How well this works will depend, I guess, on how much information the profile has in its AtoB table. I just tried it here, and while it's a bit long-winded it actually takes longer to explain than to do - so mail me off-list if you'd like more information. All the best, -- Alastair M.
