Jim
We laminate everything that we print as well. I profile through laminate all
of the time, however, there are some issues with it. There are two types of
gain that can happen to my knowledge:
1. Gain caused by the hot roller. What happens here is that the heat
liquefies the ink causing it to spread out into the paper fibers. This can
be controlled by heat and pressure settings as well as a certain paper and
ink combination.
2. The most common that I have seen is "optical" dot gain caused by
light bouncing off the dot and reflecting back onto the paper. The
reflection is caused by the lamination film. This is by far the trickiest
thing that I have had to deal with when profiling through lamination.
This gain is not necessarily linear. This is what I have found. For the sake
of numbers lets say that we would like to plot a screen of 15% cyan on a
curve. We are plotting this cyan from two different builds, one is greenish
and one is bluish - I know these are technical terms! The first build is
made up of a 15% screen of cyan and 20% yellow screen. The second build is
made up of 15% cyan and 20% magenta. The C and Y build will have a lower
value of C than the C and M build. This issue can get rather complex when
you start taking into consideration all of the variables such as the fact
that you are usually dealing with 4 colors instead of just two. Many other
things have an effect such as line screen, substrate, film specs, inks, ect.
The short answer based on my experience is that since the gain is not
necessarily linear, it is difficult to profile. You could get a perfect
match on 98% of a proof but there may be one build that is made in
illustrator that was not represented in a patch on your target. If this
build was one that is part of that non-linear gain, your profile will not
represent it accurately.
So to answer your question "Is it worth it?" I would say so as long as you
can realize the limitations in your particular situation.
Hope this helps
