Abstract
A printer capable of simultaneously forming planographic printing surface and printing ink images. The printer comprises a control unit, a plate feeding unit for continuously feeding a printing plate formed by coating an oil-repellent sheet with a fusible lipophilic thermal film, a plate making unit having a thermal head for locally and selectively heating lipophilic thermal film according to electric signals to remove portions of the lipophilic thermal film to make a planographic printing surface having a printing area, an inking unit having an inking roller for applying a liquid ink to the planographic printing surface of the printing plate, a transfer unit comprising a platen roller for continuously feeding a recording medium, and a pressure roller for pressing the planographic printing surface of the printing plate against the recording medium to transfer the inked pattern of the printing area to the recording medium. The control unit controls the plate feeding unit, the plate making unit, the linking unit and the transfer unit for synchronous operation so that the planographic printing surface is formed continuously while the inked pattern of the printing area of the printing …
