I'd agree
proofing to Quickdraw by cross rendering <RelCol> from press CMYK
is pretty hard [if not impossible] to beat in matching a film based
Cromalin or Matchprint [given a good Matchprint or Cromalin profile
to cross render from]. Of course it doesn't work with <the Quark
product> without a bit of effort.
I spent a whole day at IPEX [massive European printing (press)
show ] a few weeks back - and I didn't see one <proofer> [ie rip
based] that could print a neutral gray stepwedge. Mark Geeves from
Best USA gave a good Colour Management talk to Digital AdLab and had
some lovely Epson 10000 proofs - but the proofs produced on the Best
stand were nowhere near as good.
This is very disappointing - since the digital <proof> is fast
taking over as the <contract proof> and thus it becomes the target
for press appearance [just like in the days of film based
Cromalins]. It seems a shame that a press operator has to push and
pull his press to match a <proof> which was often made by sending
press CMYK straight to an unprofiled proofer. This misconception is
part of the story I'm sure - but if the photographers can level the
field by getting good matches to Cromalin on low cost Quickdraw
Epsons how come the rip guys can't do it?
It's a can of worms, because each <digital Cromalin> seems to be
different so what are photographers and designers to use as a guide
for image optimisation?
respect to you guys for raising your heads over the parapet.
[I'm ducking now].
