High Contrast Developers for Electronic Reprography

The entry of the industry into the electronic/computer are has put increase demands on graphic arts photography. High image contrast is still essential, but classic litho processing with its slow throughput and stability problems severely restricts potential output. The performance and mechanism of conventional developers is described as a background to the discussion of a new developer class which combines the best features of litho and continuous tone developers to yield the rapid access and image quality necessary for laser scanner applications.
