Hello, folks! Any advice about letterpress printing paper bags? We have a Challenge 15MP proof press and two table top platen presses at our shop. I’ve read suggestions on Briar Press about using softer polymer or rubber plates and/or printing with a rubber blanket on the cylinder/platen. We welcome any suggestions! Thanks so much.
Depending on how soft the bag material is (Kraft something or other, I’m guessing?) I reduce my platen packing and slip a sheet of red board into the bag to keep the impression from going through. It takes an extra couple of seconds per print, but it’s worth it!
