I use a Premier electric print dryer. The print is forced against a curved metal surface by a tightly stretched canvas. It holds two 11 x 14 prints at a time. It forces the print into a slight curve, which then strengthens it against developing a compound curve. The print is then easily flattened in the dry mount press without developing any wrinkles.
Edit: The emulsion side goes up--not against the hot metal.
May the light be with you.
