Hi Henk,
So, in your opinion, some form of "GCR" will become more and more
fashionable in the printing industry as a whole, over time? For the better?
Regardless of the subject matter?
I'm just not convinced that GCR, in general, is so superior to UCR that we
should separate all images with that technique. Granted for neutrals kinds
of subject, it is the better choice, as in silverware and four color blacks.
But for portraits, I would hesitate.
Besides, hasn't it been said that GCR affords less color control on press
than UCR? I understand for those presses that are fine tuned to a certain
print condition, that have an incredible hit rate in terms of being able to
match the proof, that GCR may help without hindering the press color
control, because it does not need all that color control if it's able to hit
the proof very well. But for those shops that don't use an exacting setup,
inks a little too far from ISO tolerances, and that are given wide proofs
variability, I think GCR would be a suicide.
So, my verdict it, yes, I think it's possible, to some extent, but the right
conditions better be in place before jumping into it.
BTW, as far as ink savings is concerned, just switching from AM to FM
screening automatically affords the printer double digit ink savings.
