Hallo Roger,
thanks for the suggestions, you probably guessed that we discussed
this already internally... I'd also like to see an "add lamination
effect" checkbox, with a choice of matte and glossy, plus a slider for
the lpi or FM dot size... but that's up to product management.
(Opinions stated are my own, of course - the usual disclaimer)
Technically, this could be done provided that we have access to the
unlaminated characterization data, or "aim values" in GMG lingo; this
is not always the case depending on how an MX4 or spot color has been
created.
Compared to just using suitable (predicted or measured)
characterization data, as you can do today, this would also affect
spot colors - a major advantage. On the other hand, it is not exactly
straightforward how to deal with manual corrections. And the inkjet
CMYK values (as displayed in the profile editor or in the spot editor)
wouldn't be valid anymore, since the laminate correction would come on
top of that. (Now ask the friendly support guys what they'd think
about explaining all that.)
Generally, when proofing for the final product (post-lam), it is also
very important to choose a substrate with a similar surface. In the
ECI working group, we found that the GMG glossy paper 250 is
convincing for glossy varnish or lamination. GMG semimatte 250 is
acceptable for matte lamination, but not optimal. In fact, we haven't
found any proofing paper or cheap lamination method (PE, PVC, 80
microns or thicker) or varnish spray that comes anywhere close to the
"premium" look of a thin (~12 microns) OPP matte lamination.
Therefore, for best results you'd need to laminate your proof (and
create an appropriate gamut or ICC proofer profile for the laminated
proof). This was also found to be very convincing, but too cumbersome
for daily production.

Hallo Hanno,
Would it be possible, technically, to incorporate your laminate
corrections,
even if not completely "proven" or tested into Colorproof 05?
Somehow? Or
Flexoproof 05? Or as some "plug-in" or adjunct of Colorproof?
And then, perhaps, there could be some user-controlled "sliders" for
the
most important dimension or parameters of the correction?
Best / Roger
