[comp.graphics] Wanted: Four color separation code

elvins@net1.ucsd.edu (T. Todd Elvins) (11/17/89)

I want to do a four color separation (cyan,magenta,yellow,black) of an
RGB image.  Does someone have an implementation of Lindbloom's
algorithm (or some other algorithm) that they could send me ?

Thanks

I would be content to just have a reference to where I might find
algorithms for color seps.  I'll get my hands on them somehow.

P.S. I take it that the referred to algorithms do something more than 
(1 - r), (1 - g), etc.
