Hi Jon,
Do you want to use customized G7 profile for proofing and/or for CMYK
conversion?
Lamination does not only change the dot gain appearance but also some
kind of saturation of the primary colors.
So what is your goal? proofing or conversion with such customized
profile?

Here is my problem.....
I need to reverse engineer the gain that occurs from film
lamination on a press sheet. I want my starting point to be the
GRACoL 2006 data set and create a new data set that would represent
a press sheet prior to lamination.
We laminate 99% of everything that we print so I have implemented
G7 based on the press sheets being laminated. I can measure the
press sheet before and after lamination to determine the gain but I
don’t know how to take this amount and subtract this gain from the
GRACoL 2006 data set.
The first question that Im going to get is “why do you want to do
that? Just use your measured press sheets to make your profiles.”
True I could. This would then be press profiles for us and they
could vary from the GRACoL 2006 data set. I want to use the
official data set as my “stake in the ground” for the whole shop.
Can anyone give me some direction to a way to accomplish this?
