PRINTING METHOD USING ON PRESS DEVELOPMENT LITHOGRAPH PRINTING PLATE PRECURSOR

摘要

Provided is a simple on press development lithograph printing plate precursor printing method for reducing wasted paper when starting a print job and avoiding occurrences of inconsistency in printed materials in which steps (i) (v) are carried out in order: (i) perform imagewise exposure of an on press development lithograph printing plate precursor and mount same upon a plate drum of a printer; (ii) spray apply moistening water and/or a water solution including an organic solvent to at least one of a water application roller which is a printer moistening water applying means a roller which supplies water to the water application roller a roller for stabilizing water volume or a metering roller; (iii) rotate the water supply roller; (iv) bring the water application roller into contact with the lithograph printing plate precursor and apply the moistening water; and (v) supply print ink from an ink application roller to the lithograph printing plate precursor and supply print paper.
