My drymounted black and white prints often have the slightest upward curl at the edges. While not large, this defect is distracting. This happens with Seal MT5 , Seal Colormount, Seal Archival, and Saunders drymounting tissue for times betw een 15 sec and 2min. Predrying the prints and museum board, as well as allowing the mounted prints to cool under a heavy weight do not seem to help. I use a S eal release paper sandwich holding the print, mounting tissue, and museum board (as instructed by Seal). I have tested my drymont temperature and it is at the recommended temperature. Have you run into this problem and what was your soluti on? Thank you.
