Ok, been gone a while or would have added this sooner. Easy fast cheap method is to take a nice sheet of clean mat board and put your dried print on it. place a sheet of clean non acid paper over the top of that and then take your trusty iron (the kind you iron your clothes with) and iron it flat. Very soothing for the times you feel frustrated to iron the he** out of a print. After I place it under a few books and all is fine.
