Abstract

A lithographic printing method of supplying emulsion ink to a lithographic printing plate via a form roller, and disrupting emulsion on the form roller. The degree of the emulsion's disruption before printing has started is different from the degree of disruption after printing has started. The duration of an idling mode can be shortened with the added advantage of reducing the development of waste paper right after the start of printing.
