QTR-Quadtone RIP

The blended color + carbon inksets have had some issues with separation in
wide format printers.  Take a look at the graphs at page 4 of
http://www.paulroark.com/BW-Info/4K+.pdf.  For that reason, I abandoned
blended inks in such printers.

On the other hand, the HP Z3100/3200 inks do not separate significantly.
 When diluted with the generic base, the cost of such inks is not bad at
all, and the lightfastness would be way more than third party blended B&W
inks.

For  my latest glossy pigment inkset approach for wide format, see
http://www.paulroark.com/BW-Info/4000-6K-Plus.pdf   I like the separate
light colors for several reasons.  I used Epson LM and LC with MIS carbon.
 That gives me very economical, low-bronzing MIS carbon with the very
lightfast Epson colors.  It also allows full 3D profiling with QTR.  The
more economical MIS light colors could, of course, be used also.  In my
view, however, so little color is actually used that on a per print basis,
the cost difference is minimal, yet the image stability difference would be
substantial.

I liked the basic approach well enough that when I went back to dyes in
wide format I stayed with the multiple grays with high gamut light colors
for toning.
