| description | A laser platemaking device for use primarily in printing comprises a system for synchronous scanning of an original and a plate material, an optoelectronic reader and a halftone pulse transducer, both optically associated with the synchronous scanning system and connected to an electronic circuit for generating a sequence of signals to control the laser beam parameters, which permits a line and a dot pattern to be produced on the plate material within a single process cycle and includes a dot and a line channel connected in parallel, a dot-line switch for automatic switchover of the line and dot channels, and a unit for registering the boundaries of halftone images, kinematically linked with the synchronous scanning system and generating commands to the dot-line switch, the laser platemaking device also comprising a laser-optical system for forming images on the surface of the plate material using a laser modulator. |
