I like Occam's Razor. Why do you need a drymount press to flatten prints? I put dry prints in a stack and sandwich them between two masonite boards. Put a 35 lb. dumbbell on top and in a couple of days, voilà! flat prints. You can do this at home.
I've done this. It works best if you take a paper napkin or cloth and lightly wet it with water; lightly wipe the back of the print and then press in a drymount press (i like doing it between clean matt boards) for a few seconds.
Otherwise I like RC for classes and the like. It's quick!
I remember driving home from class with a dozen fiber prints that were still tacky.. It was December up in Massachusetts, I had the heat on high and the prints on the dashboard.. using the heat to speed things up. Ah memories.
Blotter paper 20 or more inches wide is a tad hard to find!
Try a substitute. Fabric stores carry a material called
interfacing. It is of non-woven polyester sheeting;
hydrophobic and very inexpensive.
I sandwich prints twixt two sheets and the sandwich
twixt sheets of corrugated board. Layer upon layer
is possible. A compact, ultra light, bottom dollar
way to dry and flatten in one operation. Easy
to stow away. Dan
Use the drymount press...I sometimes heat the print to almost dry with a hair blower (works great) and then put it in the press for 30 sec, open the press to release the moisture and then close again for 30 seconds...continue till bone dry and flat.
