This is what I was seeing as well. I used to have a big problem with my
spectro and optical brightners. I would edit the white point but it only
took care of part of the problem, the light tones were still too warm,
and by the time a laminate was added to everything the problem was
increased. For the record I print large format inkjets. At one point I
was even laminating my targets then reading them with my spectro. By the
way laminates have built in UV inhibitors, so I suppose this is putting
the filter on the paper rather than in the spectro, and the lam does
have a slight warm color cast and this way it was taken into account.
I finally found a good paper with a neutral white point and this worked
great with my old DTP41 that did not have a UV filter. Since that time
the paper maker decided to change things and they added a brightner to
my favorite paper. Not very nice of them.
Fortunately I had already updated my spectro to a DTP41UV/T and I have
never looked back. The UV filter seemed to solve all my problems with
paper brightners. I read the targets these days without the laminate.
