ABSTRACT:
A printing plate laminate is formed of a carrier sheet, sticky back, a substrate and photopolymer layer. The substrate has a thickness of only about 0.2 mil to about 3 mil. The printing plate laminate can be formed from a process wherein photopolymerizable resin is coated onto a bilayer substrate, where one layer of the substrate is in contact with the photopolymer layer and has a thickness of about 0.2 mil to about 3 mil, and a second layer of the substrate has a thickness of about 4 mil to about 7 mil. A pressure sensitive adhesive lies between the first and second layers of the substrate, so that the second layer may be easily peeled away from the first layer after selectively curing and then developing the photopolymer layer.
