You're lucky to have ferrotype plates on yours. The way these work is you squeegee the excess water from the FB print (never put RC in those or you'll just wreck the plate) and put them on the plate. Emulsion down for glossy prints, emulsion on top for matte. And then, you wait for the magic to happen. When the print is dry, it should detach itself from the plate. If it's stuck, leave it longer to cook. Trying to pry it off will just damage the emulsion and make the plate a nightmare to clean.
Or at least, that's the theory on it...
