Print-flattening board?

Flat plate and bagged "lead" shot.

Just use a sheet of thick edged plate glass. Just about the worst thing you could do is spray paint metal. It will outgas for months with hydrocarbons bad for photos.

what/how to paint piece of steel to prevent rust but no outgas then?

Stainless Steel

I regret not buying one

However I dry my FB on clean screens

Then in my Hot Press

But I am moving to RC

I like RC

I have used several methods. A heavy steel baking sheet like ones used for pizza (I put the prints face-down on a sheet of acrylic so the steel does not come into contact with the image). Or, simpler yet, put the prints back in the dry mount press for a while once it has cooled. I have also put a stack of prints, sandwiched between 1/4" acrylic, on a table under a stack of a half-dozen large, heavy art books for a day or so.

All those oversized photography books we own come in handy for keeping prints flat under matboards. I also have used a spiral bound watercolor paper book to sandwich 11x14 and smaller prints or a larger 24x30 recycled paper book (plain news paper) after the press. The paper seems to absorb any additional moisture from the print as well as protect the prints until I am ready to file or mount them.
