Abstract
Lithographic plates having a granular surface consisting of a distribution of pitting having depth =10 mu, esp. ave. depth 1.5-2.5 (2) mu, are produced by passing sheet metal or strip through a rolling mill contg. one roller having a reversely grained surface. The process is cheap, can be carried out continuously, and prodn. rate is high compared to chemical- or electro-chemical graining. Small surface irregularities are tolerated.
