Patent number: 10029482Abstract: An ultraviolet curing ink can be sufficiently leveled, and attachment of, for example, dust can be prevented. In an ink-jet printer, a carriage capable of reciprocating in a scanning direction is mounted with an ink-jet head for ejecting a color ink and a clear ink and ultraviolet irradiation devices for emitting ultraviolet rays. A control unit performs control so that in the forward movement of the carriage, a color ink is ejected and applied to a medium, and in the backward movement of the carriage, ultraviolet rays are irradiated to the color ink deposited on the medium and the color ink is cured. Subsequently, the medium is fed in a feed direction, and the clear ink is ejected and applied to the surface of the cured color ink in the forward movement of the carriage. In the backward movement of the carriage, the clear ink applied to the medium is irradiated by ultraviolet rays and is cured.Type: GrantFiled: February 10, 2011Date of Patent: July 24, 2018Assignee: Mimaki Engineering Co., LTDInventors: Masakatsu Okawa, Yuko Hishida, Tomotaka Furuhata

Patent number: 9962951Abstract: Techniques are described for printing on front and back surfaces of security document substrates in a manner that conserves use of print ribbon, thereby extending the life of the print ribbon. In general, the printer controller knows the content, as well as locations and colors, of what has been printed on the front or first surface of the security document substrate. The printer control also knows the content, as well as locations and colors, of what is to be printed on the back or second surface of the security document substrate. When the back surface of the substrate is to be printed, the printer controller determines, for a particular color, whether any of the printing on the back surface would overlap with the printing on the front surface. For locations where there would be no overlap, the printer can reuse the section of print ribbon that was used to print on the front surface to print on the back surface.Type: GrantFiled: October 12, 2016Date of Patent: May 8, 2018Assignee: ENTRUST DATACARD CORPORATIONInventor: Patrick C. Cronin
