With all the reports of printing processes, something's come to my attention I want clarified.
A friend of mine has a basement literally carpeted with cards. Some of these i've noticed will curl from side to side into a U shape. My first thought was dampness, but it's a very well insulated room and there's no moisture. I tried to see what the cards had in common, and they were all Masques block foils. Add this to the list of things bad from Masques block, I guess. Shoddy foils. Anybody got a better explanation?
