Method for production of screen dot on printing block, involves comparing standard working light intensity and standard illumination period, where illustrated area of screen dot remains equal

摘要

The method involves comparing standard working light intensity and standard illumination period, where a pixel (58) lying at edge of screen dot (44) with illustration of reduced working light intensity during elongated working illumination period. The other pixel (60) lying at edge of screen dot with illustration of increased light intensity during shortened working illumination period in such a way that illustrated area of screen dot remains equal. An independent claim is also included for an exposure system for printing block comprises a controller, which has a memory unit.
