Abstract

A relief pattern is produced in the surface of a polymeric type form preform by material removal from the surface. Material is burnt away by irradiation along paths. To gain the purpose, different depths of relief area are produced along the same path by repeated irradiation along the path.

Description

technical field

[0001] The invention relates to a method and a device for producing a printing block. The printing block may, for example, be an offset printing block or a rigid printing block acting as a relief printing or gravure printing block or the like. Background technique

[0002] In order to resort to a conventional CO 2 The laser produces an offset printing block, which is generally known to burn material directly from a printing plate, which may be, for example, a polymer coating, in order to produce a relief in the printing plate in this way. However, during this process, the CO 2 The laser is permanently power modulated so the process is relatively slow.

[0003] Furthermore, in order to generate an offset printing block, PCT / EP96 / 05277 already discloses the use of two laser beam sources, the fine structure in a desired profile is obtained with the first laser beam source, while the second laser beam Source generation is at a lower level in this profile. ...
