I think I'm on my third set of fiberglas drying screens. I get them made at the local combination window place, with extra heavy-duty frames and heavy-duty screening. They fit into racks that I had built years ago. The screens are large enough to hold two 11x14's or one 16x20 with extra room. The racks were designed so that there's only about an inch between screens. The prints [face up] do tend to curl some, and I correct for that by putting in the mount press or in two very large books presses with inter-leaved archival boards. Prints go in face-down, with the backing board slightly moistened. The whole thing is screwed down tight and left for a couple of days. Voila, no curl.
