just a quick response and then I'll do a little digging Jeffrey...I've
not printing with these desktop negs. before, but I do understand what
you're experiencing

You're seeing the effect of pre-press technology know as either UCR
(under color removal) or GCR (gray color removal) which indeed reduce
the amounts of colors, other than black, when black is present.
The printing press can produce a fine black with less additional colors,
so it uses these schemes to effectively reduce the total amount of ink,
to speed drying, and reduce waste. I believe you can either turn these
off or at least modify them to respond in the way you desire...that's
the part I'd have to look up and test
good work, very interesting
