Abstract

886,869. Contact printing on curved plates. REGAN INDUSTRIES Inc. March 16, 1960 [Aug. 18, 1959], No. 9342/60. Class 98(2). Contact printing apparatus for a curved plate comprises a curved plate holder 12 to which the plate and negative are pressed by a resilient blanket 40 having a transparent region 44 for passage therethrough of light from a source on the convex side of the curved resilient blanket, the latter being held firmly at its margins to the plate holder by suction means. As shown in Fig. 1 the light source 60 is mounted on the inside of a semicylindrical cover 62 which can swing down to cover the blanket. Suction is provided by pump 24 connected by a conduit manifold to a groove round the edges of the plate holder into which the marginal regions of the blanket are drawn. An additional conduit provides suction at the edges of the plate and negative. Preferably, the side of the blanket towards the plate holder has a pattern of waffle-like protuberances (Fig. 6) to allow withdrawal of air via the manifold from virtually the entire underside of the blanket.
