QTR-Quadtone RIP

Hi Tyler. I'll gladly defer to your experience and knowledge. I did
allude to some of the things you expanded apon but you say them much
better. You are right of course about the workspace info.
I have noticed what you mentioned about QTR near the 100% region. It
was when I was working with glossy/semi-gloss papers. The limits,
among other things, became very critical. I don't work much with
B&W/QTR and glossy(older machines) so haven't devoted a lot of time to
tinkering with them.
It is much easier to get excellent(IMHO of course-you might think them
terrible) results with matt papers. Since I don't have to satisfy
client needs, I only have to deal with my own limited ones so there is
still a lot to learn about rips and QTR. I work with the issues as
they come up. I like to think of it as "learning by disaster";-) It's
less painfull that way.
Thanks for the preserve color # tip. I'll have to try that for fun.
It will be nice to screw up intentionaly for a change.


Regards
Duane
