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,
