Pd/Pt Print flattening

Not totally related to DN, but what is the best way to flatten a Pd print paper after it has dried? Will an iron on low ruin the print?

Low heat or even moderate heat won’t harm the print. I use a dry-mount press that I’ve had since the '80s. I think if I was using an iron I would put the print face down and use some sort of slip sheet so as not to mar the paper.
