This is the exact same press I posted about yesterday. The platen and pad are slightly over 11X14. I have been using this press recently to mount 11X14 prints on 16X20 mounts with no problems. Just make sure you sandwhich the print and board you are mounting with a board on both the top and bottom. The press works fine for me. I think these go for at least $500 new and you got a good deal.
