I have found the pigment inks on pictorico to have
unexpectedly higher density with both gum and ziatypes.I
havn't quantified it at all but when I set my curve for
a .8 density range, as read by my densitometer, it is
too much for gum and not too bad for the ziatypes. This
is goodness because when you try to use all the density
that pictorico is capable of the curve get's way non-
linear, it's best to stay under 1.0 or so (densitometer
measurement).
A side note on this is the only quadtone ink that dries
fast enough for pictorico is the peizo ink, which then
needs an overcoat spray to keep it from smudging. I was
hoping the much less expensive MIS-FS inks would work as
well but I saw a note from Nick that they did not dry
well enough.
I'm trying to get time to try the MIS-Wolff work flow
with the Epson driver and the Peizo inks, should cover
the pictorico zero dot gain 'problem' better than the
non-dithered peizo driver does. Maybe this weekend.
