PROBLEM TO BE SOLVED: To accomplish the shallowness, quittance from an aromatic solvent, and the like of a gravure cylinder plate. SOLUTION: This printing apparatus acts to apply direct voltage between the gravure electrode, opposed electrodes being adjacent thereto and immersed in a nonaqueous resin dispersion type ink, and an impression cylinder coated with a conductive rubber to be in press contact with the gravure cylinder. Voltage difference is established between the gravure plate and the opposed electrodes in an ink pan with the nonaqueous resin dispersion type ink contained therein so as to allow the nonaqueous resin dispersion type ink to adhere to the gravure cylinder plate, and further, by means of a doctor blade, the nonaqueous resin dispersion type ink is scraped off from the non-image forming part, after that, the nonaqueous resin dispersion type ink staying in the recessed parts of the gravure cylinder plate is transferred to a body to be printed by establishing electric potential difference between the gravure cylinder and the impression cylinder. |
