My hot press has a platen size of 19x16. Because of the way arm is made, it is possible to slide larger piece side ways.

Is it possible or even advisable to try to press, say 16x20 print, and come out looking perfectly pressed? Or, would it cause a crease where the platen ended? For the same token, is it possible/advisable to try to dry mount larger prints than the platen size?

In theory, it looks as if the ridge on the form caused by years of use might cause problems but I have no ways to try this, yet.

I am not interested in trying to use any other method for flattening the print. If you have an actual experience, I'm interested in hearing from you.

Thank you.
