I am looking for a CMY-only (no black ink) profile that uses FOGRA39, for the purpose of converting colors from an arbitrary color space in RGB or CMYK to another in CMYK, keeping colors as faithful as possible to the original without using any black ink whatsoever, and prints somewhat reliably on an average printer (being in Europe, I assume FOGRA39 is a sensible average target). Or, better yet, I would like to know how to create one myself with a software that is free as in beer, so that I can have several with different maximum total ink. Ideally, that software would run on Mac OS X. I have never created a profile and I am not one bit familiar in what it involves and what I should be sure to doublecheck. I stumbled onto Argyll’s fakeCMY (http://www.argyllcms.com/doc/fakeCMY.html), the description of which sounds somewhat related to what I want, but not quite so:
This tool is a means of producing a CMY to CMYK separation. A fake CMY profile is created from the output of fakeCMY, and this is then linked to the original CMYK profile using collink, to create a separation containing the desired black generation.
That actually sounds the reverse of what I want to do. It also seems to hint that the final purpose is producing a device link profile, but I do not think that is what I need since I want to be able to convert from arbitrary color spaces (I have never dealt with device link profiles either). And, at any rate, I would not know what to do with a .ti3 file afterwards. Alternatively, (or additionally, to be able to compare if anything) I would like to find/create a CMYK using FOGRA39 that uses a strong UCR-like separation so that black is ideally used only on neutral values. Any hints or sources or where to go?
