Method for use in top end of exposure drum for controlling vacuum distribution in exposure unit for recording artwork on printing block, particularly printing plate, involves forming contact surface by printing block receiver surface area

摘要

The method involves forming a contact surface (10) by a surface area of a printing block receiver (1). A valve of a vacuum access (120) is connected with or separated from a vacuum space (124) by the printing block receiver. Each connected vacuum access is linked with a vacuum chamber (11,14) which is evacuated and connected with multiple vacuum channels over multiple vacuum bores in the contact surface, such that the vacuum channels are impinged with vacuum by the vacuum access. An independent claim is included for a device for controlling the vacuum distribution in an exposure unit for recording artwork on a printing block, particularly a printing plate.
