Hello,
I once had the brilliant idea to use my press to finish drying partially dried fiber prints and thats pretty much what happened, big wrinkles all over the place once the prints finally dried out. Solution is 1) to squeegy the prints with great care to get all the surface water off, back and front, befor racking them. If not then there will be wet areas even when the print seems dry. 2) Let them dry, in my experience 24 hours is not long enough unless your in a dry climate. I had to twiddle my thumbs nearly three days this week because the humidity was up over 70% and those 16x20 weren't drying out.
Good luck
Chris
