Abstract
A contact printer for producing graphic material, such as engraving plates, by exposing a metallic surface by means of a light source emitting ultra-violet light. The light source is situated in a box with a lid which can be tipped up. Inside the box, a vacuum frame is provided which can be tipped down from a horizontal position below the lid to an inclined position for the exposure. The resulting apparatus is very compact, and simultaneously, an almost uniform exposure over the entire metallic surface is achieved.
