QTR-Quadtone RIP

Hi John, Thanks for sharing your knowledge about this topic. At this
point, since I need to modify the existing curve that I am using for
the Ilford Smooth Pearl paper, I need to review the procedure for
creating QTR Curves. Hopefully this will help me to apply the
procedure that you outlined. Using the curves for Epson Enhanced matte
and Moab Entrada Natural has resulted in a satisfactory screen/print
match when using the Epson MK black ink. Hopefully, by modifying the
curve, I can get a little closer to this with the Ilford paper using
the Epson PK black ink.

Best wishes,

Ken
