You are right - I don't care about any of that. A lot of publishers
require images to be uploaded in CMYK format for their printing process.
I don't want to buy Photoshop just for that!

Subject: Re: RGB to CMYK
Hmmm.
For which RGB phosphors?
For what white point?
For which CMYK inks?
For what substrate?
If you don't care about any of that, it's pretty straight-forward.
The 1-Color thing will probably work OK, and you can do simple under-
color removal for the black. I've got some code around somewhere
that does that, and halftones it as well if you wish. I assume you
want this for printing, or print proofing?
I don't have an ImageJ plugin, but I do have the code that I
mentioned above. If you can tell me why it's a good idea, I might be
convinced to create a plugin.
Cheers,
duane
