An Investigation of the Effect Plate Exposure has on Dot Change, Comparing a New Dry Process Silverless Film with Conventional Silver Film

The dot change effects that are associated with a new non-silver dry-processed graphic arts film are described. The new film is compared to traditional silver film for platemaking and on press for two different press runs. The objective of this preliminary research was to see what effect varying plate exposures will have on the new film comparative to traditional silver film. This paper discusses the imaging process, the platemaking characteristics and the information gained from both the conventional lithographic press run and the waterless lithographic press run.
