Hi Daniel,

I have experimented quite extensively with various coating techniques
but GLOP I have never used though I have followed the threads on GLOP
with great interest.

My guess is the GLOP designed for glossy papers is made so that it can
be delivered through the printer ink delivery system so it has to be
very thin. This works great on glossy paper because it doesn't absorb
much of the liquid. But on matte paper ...

You can try creating IJC/OPM or QTR profiles using only the GLOP and
put on successive coatings with drying time in between.

In my coating approach which employs an airbrush I also have to apply
multiple coats to increase dmax. But I'm afraid you may find it takes
too many coats of GLOP to achieve the dmax of glossy papers. Why don't
you try this to find out if this is possible at all.

I was going to suggest you apply enough GLOP to seal the matte papers
then use a resin-based lacquer or Golden MSA spray on top to quickly
get the incredible dmax. But someone (Steve Kale?) found out that the
GLOP blisters horribly when touched by these sprays. This is not a
problem with the separation coating I use (Golden GAC 500).

I now have pretty much given up trying to coat matte papers to get
high dmax. What you end up with is a glossy surface which no longer
resembles the original fineart surface you want to preserve. Now I
coat just to protect the print. Now it turns out the "fogging"
technique suggested by Douglas Stockdale (in the Print spraying &
glazing thread) works incredibly well.
