Abstract:
1. A method of producing a relief image from a liquid photopolymerizable resin, said method comprising the steps of: a) placing a coverfilm onto an exposure glass; b) casting a liquid photopolymerizable resin layer onto the coverfilm; c) laminating a substrate to a surface of the liquid photopolymerizable resin layer that is opposite to the coverfilm as the liquid photopolymerizable resin layer is being cast onto the coverfilm; d) placing an image or film negative on top of the substrate; and e) exposing the liquid photopolymerizable resin layer through the image or film negative from the backside of the liquid photopolymerizable resin layer to selectively crosslink and cure the photopolymerizable resin layer and form a cured relief image, wherein the total height of the cast liquid photopolymerizable resin layer is higher than the resulting total height of the cured relief image.
