Hughes Case 3 PLATEMAKING APPARATUS Abstract of the Disclosure The invention is an improved liquid photopolymer applica- tor means for use on photorelief printing platemaking machines. The applicator means comprises a substantially vertical plate which acts as both the rear wall of the applicator means and as a doctor blade for uniformly spreading the photopolymer. The re- maining sides of the applicator means form a scoop means which is substantially movably connected to the vertical plate to define a bottom slot-like opening immediately in front of the vertical plate to discharge the photopolymer at a controlled rate, said photopolymer being doctored by the vertical plate as the entire assembly traverses the length of the platemaking machine.
