Hopefully someone can help me out with this serious problem! I am using AZO paper, and dry mounting it too Artcare 4ply board using various drymount tissue (Seal MT5, Color Mount, Arisa Drymount). A few days after dry mounting, my prints start to get large air bubbles below the print! I heat press the board and print at 220 before drymounting, then usually drymount for 2-3 minutes on 220 degrees then use a cold metal weight too cold press the print. My prints are stored flat, in a cool (78degree) room. In a few days, air bubbles start appearing on the prints and I have to get rid of them! They are not exposed to heat, sun, moisture, or anything of the sorts. Has anyone else had this problem with single weight AZO? Thanks for your help.
