In frames it would not surprise me at all if glycerol is carried over by
other ink media components that evaporate faster and then condensate on
the cooler glass. The more when enough light is there to heat the print.
Most likely the effects of static electricity etc add to that effect. It
could be a nice project for a PhD to find all the details of that transfer.

Just a few thoughts on this if I may... I used to
do many art shows every year.. Out gassing used to make me nuts.. I had a travel
kit that would allow me to dis-assemble and re-assemble framed pieces with me
all the time. Typically the kiss of death was when the piece got heated up and
it was especially tuff if the piece had a lot of dark colors that would absorb
the heat and hold it..
So I also shot and processed film here and have a
great Arkay stainless steel vertical dryer.. I started processing prints
thru it and it honestly really made a difference.. It has both blower and
a heat system and vents to outside the cabinet. The air is moving in
this thing all the time.....you can still put the piece in enough heat and
it will always make it outgas some more.. seriously however I feel that this
maybe solved 85/95 % of my issues. I can stand up a rolled 60 inch print in this
thing by removing the interior wire shelves.. Their efficient, you can
"overdry" a piece pretty quickly but of course they will settle in at the local
humidity level when the dust settles..
So no it doesn't totally solve the problem but it
the closest thing I've found so far.. My guess is these would be cost
effective now as not much film is getting done these days. I would honestly
suggest looking into one if the shoe fits..
