摘要
A step-and-repeat registration system is disclosed for making multiple- image plates for use in flexographic printers or the like. The negative which carries the image to be transferred to a light-sensitive film, is referenced with respect to a fixed frame. An incremental step registration system accurately positions the film at a succession of predetermined stations to bring different portions of the film opposite the negative. At each station the film is brought into contact with the negative and an exposure is made on the pertinent film portion, using a light source to project the image onto the film. The registration system provides high accuracy and lends itself to partial or complete automation.
