Is there any other way to convert to a specific CMYK color space, preferably with Photoshop, but altering the default separation algorithm so that K is not used and CMY are increased in order to compensate that lack so that colors remain as close as possible to the original, taking also into account a custom TAC? I do understand that the deviation from the original colors will inevitably be higher on black-ish tones if no K is used.


I’m not sure what else you’d expect to happen here?

If you build the ICC profile in Argyll using -kz -l300 -L0 you are going to create CMYK with no K and the CMY channels compensating as best they can for the missing K.

Keep in mind that you'll need a pro CMYK proofing system to appreciate and validate the results of these conversions — Photoshop isn’t going to be very useful…

And, if you want to keep things really simple, why not just invert the RGB channels and avoid black generation altogether ;-)
