Digital BW, The Print

Thanks Paul,
I am using quadtone rip with my own ink separations (folowing Roy's
QTR procedure) so I will give these three greys a try.

One other thing I noticed when making ink separations is that there is
a (big) difference in the place of the separation points between paper
(EAM and Photorag) and transparent media (Pictorico OHP and Agfa
CopyJet the two best media available). You really can't use the same
separation. Translucent behaviour of the inks is different than
reflective (as all alt. photo digital negative makers probably
allready know).

Those are
