Abstract
A method of lithographic printing comprising forming an image based on signals of image data directly on a printing plate precursor mounted on a plate cylinder of a printing press, thereby preparing a printing plate, and conducting lithographic printing, wherein the formation of image on the printing plate precursor is carried out by an ink jet recording method in which oil-based ink is ejected utilizing an electrostatic field. According to the method of the present invention, a large number of prints having clear images can be obtained. Further, a printing plate is directly formed corresponding to digital image data in a printing press, and lithographic printing is performed at a low cost and a high speed.
