Abstract
A system for making printing plates for newspaper, which can make, with great efficiency, replacement printing plates to be used when a printing face of the printing plate mounted on the plate cylinder of the rotary press is to be changed in part. The plate-making system is built by linearly arranging in series a plate feeder 2, an exposure unit 3, and a developer 5 so that the exposure unit 3 may directly form images on the printing faces of a plate material 12 in accordance with image drawing signals from a computer to make a printing plate P large enough for at least several pages. On the downstream side of the developer 5 are provided: a borer 7 for making positioning notches 12a and positioning holes 12b in the plate material 12 (for several pages of newspaper) as discharged from the developer 5; a cutter 12 for cutting the plate material 12 (for several pages of newspaper) from the borer 7 into several plate materials 12', each the size one page of newspaper; a first bender for forming bends 12c, for mounting the printing plate on the rotary press, in the plate material 12 (for several pages of newspaper) which plate material has not been cut by the cutter 8 after being bored by the borer 7; and a second bender for forming bends 12c, for mounting the printing plate on the rotary press, in several one page size plate materials 12' which have been obtained by cutting the plate material 12 by the cutter 8 after boring by the borer 7.
