Abstract

Presensitized lithographic plates having a diazo layer are prepared such that they exhibit a photospeed rendering them suitable for ultra high speed operations including use within laser platemaking systems. These ultra high speed plates have a diazo layer that is exceedingly thin while still being generally uniformly distributed throughout the plate area. The process includes extracting a significant quantity of diazonuim compound or diazonium resin from a diazo layer on a presensitized plate substrate. Plates thus formed are useful in laser exposures for facsimile transmissions, as projection plates, as camera back plates, for step and repeat plate work, and where low intensity light sources are used in conjuction with very large plates.
