QTR-Quadtone RIP

The differences you are seeing may well be less than you think.
Depending on your densitometer, they might be within it's measurement
tolerances. Also different printers are very unlikely to give exact
matches. There are differences in max/min dot sizes, possible head
voltage diferences, age and head wear differences between the two
printers, the fact that the two printers were designed for different
inks to begin with and a host of other variables. In actuality you are
getting very good results with both in terms of d'max.
