摘要 PURPOSE:To dispense with lithographic plate making and mounting works, by a method Wherein the outer surface corresponding to an image line part of a magnetic drum is magnetized to form a magnetic latent image and a magnetic fine powder with a surface subjected to ink compatibility treatment is transferred to a plate cylinder to which ink repelling treatment is applied and ink is supplied to the magnetic fine powder part of the plate cylinder to perform printing. CONSTITUTION:After image data is converted to the data of an image line part to be magnetized, the data corresponding to the image line part is sent to a magnetic head 1 and the part corresponding to the image line part of a magnetic drum 1 is magnetized. When the outer surface magnetized of the magnetic drum 1 passes a magnetic fine powder supply part 4, a magnetic powder containing a fixing agent and having a surface receiving ink compatibility treatment is supplied to the magnetic drum 1 to be adhered and held only to the magnetic latent image part and subsequently brought into contact with a plate cylinder 7. After the magnetic powder supply and fixing processes are finished, the plate cylinder 7 passes an ink supply part 6 and ink is applied to the magnetic fine powder fixing part of the plate cylinder 7.
