Speaking of CTP in this chain, I was at a printer last week where we
experimented with "linear" vs "dot-gained" CTP and it turns out that, in
order to match the bulk of separarations work still being pumped up
conventionnally by today's separations houses (and what not), a
conscientious lithographer has no choice but to run its CTP in a way that
the gain between dot percentages in, let's say Photoshop, and the measured
Apparent Dot Area on the printed sheet has to be in what it was in the film
to analog plate days, which is 22% for black, 20% for cyan and magenta and
20% for yellow.
Is there a consensus on what to run CTP at in North America nowadays? Are
there shops that run their CTP "linear"?
