RE: pt/pd mounting > gum framing
I'm certain buffered board has been shown to slow down image and paper degradation due to acidity when print and mount are in a sealed or almost sealed environment such as a frame (it is said that a small gap should be left in the sealing tape to allow the frame to "breathe" and so avoid condensation). Unless, of course, a high pH is antagonistic to the print! Anyway, this might be slightly off topic, but an article by Michael A. Smith has a little bearing on this subject and will possibly be of interest to those who are interested in these things: http://www.superiorarchivalmats.com/sam/Article.html Liam
