Andrew, based on your experience, how long does it take, on average, for
proofs made with Ultrachrome pigment inks to dry down, stabilize and show a
reliable appearance?
Put another way, how much do prints made with these inks shift, and when do
they stop shifting? If we were to gauge it, which colors shift the most and
to what degree?
In production environments it is highly impractical to ask designers to wait
a couple of hours, or three, before they are able to see a "stabilized"
print. Most often, they want to see it NOW: waiting is a luxury that simply
cannot be afforded.
Is there really such a visibly dramatic shift in color and tone that, if I
show a designer an Ultrachrome inkjet proof made, say, 10 minutes ago, it is
bound to lead to DRAMATICALLY wrong results? Or just SLIGHTLY wrong, within
acceptable margins?
(Of course "acceptable" depends on the circumstances, but I am referring
here mainly to proofs for packaging to be printed on either web offset or
flexo, and only occasionally on sheetfed litho.)
Thank you.
