QTR-Quadtone RIP

Mark,

This is probably pretty obvious, but did you change the dither pattern
and the Speed vs. Better selection? With my quad inks, I got rough
tonal seperation and dither "grain". However, when I switched to
Adaptive Hybid and Better, my problems largely went away. (I use the
7000 with Piezography Selenium inks.)
