GRAVURE PRINTING APPARATUS |
摘要 |
Apparatus is provided for making a plate cylinder of an intaglio plate that can be used in gravure printing. The apparatus includes a printing plate sheet made of a thermoplastic resin and wrapped around a metal cylinder. A semiconductor laser source irradiates the circumferential surface of the printing plate sheet with a laser beam to form concave portions or cells on the circumferential surface of the printing plate sheet in response to the tones of a picture. The sheet with the holes formed therein is used as a printing plate. A plate cylinder for intaglio printing is thus formed directly by using an electrical signal.
