Advances in Archival Mounting and Storage by Michael A. Smith and ‘Inherent Vice’ and Quality A Photograph Conservator’s View by Barbara E. Lemmen) played a big role in my decision. I get the ArtCare Archival Foamboard through a local framing shop. Controlling the entire process from taking the shot to mounting the print is a hobby for me. My prints are not destined for a museum or for profit. They are destined for my pleasure and the pleasure of friends and family and the occasional art gallery supporter who is willing to support the gallery by buying one of my prints. I donate a print, and the gallery sells it in an auction as a fundraiser. It's my way of donating to the gallery.
As for your concerns, they are valid, and I have taken measures to avoid such problems. Besides using archival foamboard, I have refurbished my drymount press so the temperature is quite accurate and the pressure is minimal and uniform. I have never had the foamboard fail.
