Abstract

An on-press recording type lithographic printing method involving an ink jet process which comprises ejecting an oil-based ink onto a printing plate material mounted on the plate cylinder of a press utilizing an electrostatic field according to signals of image data, whereby an image is directly formed on the surface of said printing plate precursor, thereby preparing a printing plate which is then used as it is to effect lithographic printing, characterized in that when any abnormality occurs, the formation of image is suspended and/or the cause of abnormality is removed.
