QTR-Quadtone RIP

Hi Dave,

With QTR you don't apply any of Paul Roark's curves. You just send a plain
grayscale TIFF file. Paul's curves are for printing with the Epson driver
while QTR curves are for printing with QTR only.

I have curves both for the standard inkset and for an inkset where the eboni
black ink is replaced with the MIS PKN photo black ink and the yellow sepia
ink is replaced with MIS gloss optimizer. There are three curves for the
standard UT7 inkset with Eboni:

UT7-EEnhMatte-cool
UT7-EEnhMatte-neutral
UT7-EEnhMatte-carbon

The rest have PKN in the filename and are for the PKN inkset and various
glossy papers.

I'm waiting for an XRite 810 densitometer, and I expect to re-linearize all
my curves once it arrives. I'll post an update to the list once the curves
are complete.
