Abstract
By increasing the printing-plate-making speed in a laser-direct-drawing-from-computer type plate making system, the plate size can be increased without large-scale expansion of the plate making facilities, and the operation time of the rotary press is thereby improved to increase the number of newspaper prints. The invention provides a printing-plate-making method for newspaper printing designed to enable figure-drawing corresponding to drawing image signals from an electronic computer by laser beam. A plurality of laser scanning heads are provided in an electrostatic charging and figure-drawing image signals from the electronic computer to draw similar or different figures on a plurality of plates in parallel. The plates thus drawn are then subjected to a developing and fixing section, an elution section, post-treatment section, etc.
