Printing form blank producing method, involves deriving indexing feed of array of laser diodes from number of image dots and number of laser diodes per rotation of printing form blank

摘要

The method involves selecting a number of laser diodes (20) disposed along a straight line at an equal spacing distance. A determination is made for writing a number of image dots within a spacing distance of two adjacent diodes based on a resolution to be produced. An indexing feed of array of laser diodes is derived from the number of image dots and the number of laser diodes per rotation of a printing form blank.
