As far as I've been able to find out in researching archival processing
for conventional silver-gelatin prints dry mounting is very archival in the
sense that it does not attack the image or support. However, it seems to be
frowned upon by galleries because the print and mat are hard to separate.
In fact, there are now some dry mounting tissues which do allow removal of
the print fairly easily.
I don't know if this applies to prints made by alternative methods on
thin or unsized paper. Its possible the dry mounting adhesive might migrate
through some kinds of paper. It doesn't seem to do this to photographic
paper but that is heavily sized with either gelatin or plastic.
There is cloth tape made for archival mounting of both photos and
documents. Both the tape and adhesive are supposed to be neutral pH and
free of anything which attacks paper or photo images. Anything can be
mounted by making "hinges" out of this stuff. Again, the adhesive may bleed
through some paper. Photo corners are non adhesive and might work where
adhesive is not desired.
