ON-MACHINE DRAWING LITHOGRAPHIC PRINTING METHOD AND DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an on-machine drawing lithographic printing method by which a large number of printed matters showing a clear-cut image can be printed rapidly and at a low cost, with the capability of dealing with digital image data as well as an on-machine drawing lithographic printing device.;SOLUTION: This on-machine drawing lithographic printing method comprises the steps of mounting a printing plate material on a plate cylinder of a printer, creating a printing plate by forming an image directly on the printing plate material by an ink jet process to discharge an oil ink from a recording head using an electrostatic field based on a signal of image data and further and performing a lithographic printing process in succession with the use of the printing plate as it is. In this method, an agglomerate or a sediment of the oil ink is redispersed.;COPYRIGHT: (C)2002,JPO
