Claims

[Scope of Claim for Utility Model Registration] A plate roll that is rotationally driven by a drive source and has a plate portion engraved on its circumferential surface; an ink supply device that supplies ink to the circumferential surface of the plate roll; and an ink supply device that supplies ink to the circumferential surface of the plate roll. A scraper that scrapes ink from the circumferential surface of the plate roll in sliding contact and leaves ink only on the engraved plate portion, and a scraper that is arranged parallel to and in contact with the plate roll and rotates in synchronization with the plate roll by a drive source. In a printing device comprising a transfer roll that transfers the ink on the surface of the plate roll to the circumferential surface and then contacts the printing medium to print the ink on the printing medium, the transfer roll transfers the ink on the surface of the plate roll at least on the surface is formed of a deformable elastic material into a shape that roughly follows the outer shape of the printing medium, and the transfer roll is pressed against the plate roll using a pressing force that deforms the surface portion of the transfer roll into a shape that roughly follows the surface of the plate roll. A printing device characterized in that it is arranged by pressing.
