I've used the ACME plates a few times. I print some test plates, resizing in word until they print out at the right scale size. When I get the size right I print out a few, cut them out and glue them to a piece of flattened beer can aluminium with Future. Once dry, I cut the aluminium plate close to the plate image, then coat the whole thing with more Future. Sometimes, if the Futured paper image has a texture, I will sand it smooth with fine sandpaper, apply another coat of Future, then glue the plate to the model, usually with CA.
