Ron,

Now that is a new one and very interesting! Any feel for how long you need
to let prints dry or cure before you frame them?

Epson and Ilford both say let the prints dry for 24 hrs, but I've heard that
certain household chemicals or cleaning products can damage the inks even
after drying.

I noticed the "gassing" the most on Epson's Luster paper.

Yep.  Out-gassing is a by-product of using RC or barrier-type papers.

It has been discussed on the Epson Leben list a long time ago.
Happened with dye inks too. Possibly glycol, alcohol that
evaporates from the print that takes another fraction glycerol,
PVA with it and condenses on the glass in front. With light
falling on the darker parts of the print behind the glass there
can be more temperature buildup in those parts and a direct
transfer to glass that is colder is possible. Maybe static
charges help in that transfer and reduce the spread of the
condensation. There were other hypothesi though.

I've also experienced this problem, but only with RC papers - not the  
matte papers.  I put RC prints between a couple of sheets of copy paper  
for a day or two and that seems to solve the problem.  Most of the  
outgassing condensation is absorbed by the copy paper and you will see  
this as the copy paper will wrinkle and buckle.

Helene,

I don't know about 'common wisdom'. The instructions from Epson on my pack
of Premium Glossy tell me to "Dry your printouts for a least 15 minutes and
put a sheet of plain paper or other absorbent paper between them to stack
them. For best results, dry your printouts for a full day".

Ron seems to be suggesting they should be dried for longer before being
mounted behind glass.
