摘要

Production of a photo polymer printing plate comprises casting a layer (7) of polymerizable liquid (5) on a plate (1). The air pressure beneath the plate is then increased to keep the plate level while the layer is irradiated to cure the polymer. An Independent claim is included for a device for carrying out the above process using a box (2) with the plate mounted at the top and a compressed air source (3) connected to its interior.
