PURPOSE:To execute easily position matching of an original and a photoengraving material by superposing directly a light transmitting original whose size is larger than the photoengraving material, on the photoenegraving material, pressing the original successively by a squeegee roll, and making it contact closely in a vacuum to the photoengraving material. CONSTITUTION:A light transmitting original 4 is formed to larger size than photoengraving material 3 placed on a printing base 1. A squeegee roll 7 consists of a large diameter part 7a of both end parts and an intermediate part 7b and its radius difference is made almost equal to thickness of the photoengraving material 3. The original 4 is superposed on the photoengraving material 3, both of them are fitted to the squeegee roll small diameter part 7b and the printing base 1, the original 4 is made to press-contact with the photoengraving material 3, is pressed successively by the roll 7, is made to contact closely in a vacuum through a vacuous groove 2, and thereafter, printing is excuted. Therefore, position matching of the original 4 and the photoengraving material 3 is executed easily, and the printing work time can be shortened. |
