I bought out a shop that had a presstek 52. It was gone when I acquired the shop. In the store room was a bunch of cases of pearl plates (DI). They are approx 20.5 inches wide. Will these fit a 52? I'm not sure, I'd like to sell them and the other supplies (platecleaner cloths). But am not sure of the plate size on a 52. P/tek's website is a bit vague on the size. Any help or interest would be appreciated.
