Have you measured the temperature in the drying cabinet while it is running? It could easily be quite extreme, hair dryers have been known to precipitate life changing relocations by overheating and setting fire to soft furnishings, so just cause its designed for hair does not mean its cool!

Thanks, Robert, Richard & Ken, for your responses to my query about "wrinkling" release paper (dry mount pressure was too tight, I discovered). With trial/error/tweaking, I got beautifully & firmly mounted prints this evening, but further testing of the bond uncovered a brand new query.Prior to this, I had been using a dry, pressure-sensitive adhesive (Studio-Tac) for my photo collages. I live in a *very* damp climate, w/my studio & display space in the basement. When I showed some work in a dryer climate last winter, a horribly dry/overheated place, edge separation of the prints from the matboard substrate became increasingly evident over the course of the month. (Luckily for me it was a sparsely attended venue!)An ingenious friend who saw the show, a former pre-digital pro photog known for painstaking building of his own sets, etc., suggested I test the dry mounted prints for edge separation, in an effort to avoid this situation in the future. The results were not good. Per his suggestion, I put the drymounted prints (two 11x14's, butted up against each other on a long, narrow strip of matboard-a typical collage composition) into my homemade film drying cabinet, a well-sealed plywood box with a hairdryer nozzle sticking thru a hole in the bottom of the box.I turned the 1500W hairdryer to the "hot" and "high" settings, placed the short edge of the board on the floor of the cabinet, closed the door, and let it run for about 15 minutes. The bottom 1/2 of the board (closest to the hairdryer) curled away from the print, almost completely delaminating the print from the board. The top half fared much better, with the bond failing only on the edge closest to the hairdryer.I assume I subjected this sample to extreme conditions....or *did* I? I keep remembering that overheated dry room last winter, enough to make one's skin crawl, and wonder whether the hairdryer in the cabinet was *really* much more extreme?I'd welcome anyone's experiences/opinions, I have 2 pieces in a show coming up, and would be mortified if this happened to me again throughout the run of the show, since it is a much more important venue.Thanks for saving my arse, AGAIN, folks!!
