QTR-Quadtone RIP

Alan

SG is essentially a colour inkset (albeit with reduced gamut) with a
single black. Since QTR is not a colour RIP, I suspect you might have
more success with the SG inks using the Epson driver and the Lyson ICC
profiles. Once you receive Printfix you will be able to create your
own ICC's for the paper you want to use (again for use with the Epson
driver).

I could be wrong of course, but with a single black it does not seem
practical to construct curves in the manner QTR permits with the Epson
Ultrachrome inkset with 2 or 3 blacks. The other alternative is to
construct magenta and cyan curves blended with black and then combine
these curves with yellow to create something near neutral. That sounds
to me like one would be trying to do manually what a colour RIP would do. 

Sorry to sound so negative about your venture. Perhaps someone else
has discovered a way to do what you want and will chime in. If you do
decide to continue with QTR and the Lyson SG inks, please keep us
posted as to your progress.
