What a bunch of baloney. When Adobe is good and ready they will tell us
peasants how to do this. Feh. 

I got my hands on a separation that was produced by the Adobe Separator, and
was able to reverse-engineer it. It's actually one of the best-quality pieces
of PostScript code I have ever seen, and was very easy to understand and to
modify. Basically, the knowledge that it was at all possible, and one
example, was enough for me to solve my problem. Of course, I just wanted to
separate against standard process colors, and I didn't need any fancy stuff,
and I didn't need spot color, and my application is not very sensitive to
incorrect halftoning, so it went quite well.

While I can understand Adobe's position about not wanting to release code
that is not perfect, especially given the vile dreck bad PostScript that so
many applications generate, at some point enough becomes enough and you
should just let people have what's there so we can get our work done.

My kudos to whomever wrote the "Adobe_separation" ProcSet. It's a
masterpiece. I know I'm somewhat of a stranger to this newsgroup, but, trust
me, I'm no stranger to PostScript and my kudos with respect to code quality
don't come easily.
