I printed a lot of postcards for family on Ilford postcard paper. I'm concerned at how well they are going to get through the mail...I know one drop of water and that RC paper is going to stick to whatever is beside it and be ruined, not to mention scratches etc. If I laminate the postcards, will it hurt the silver gelatine paper; that is, will the laminating machine melt it or anything? And will the post office accept laminated postcards?
