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.
Claims13
A lithographic printing method of performing lithographic printing by supplying emulsion ink to a lithographic printing plate via a form roller, comprising the steps of:
- supplying the emulsion ink to the form roller;
- and
- disrupting emulsion on the form roller, with a degree of the emulsion's disruption after a start of printing being different from that before the start of printing.
An ink supplying apparatus for supplying emulsion ink to a lithographic printing plate via a form roller, comprising the form roller from which emulsion ink is supplied, an emulsion disruptor for disrupting emulsion in the emulsion ink on the form roller, and an emulsion disruption controller by which a degree of disruption of the emulsion by the emulsion disrupter after a start of printing is differentiated from that before the start of printing.
