  • Patent number: 9108409
    Abstract: The invention prevents inconveniences from being caused by ejection failure and unintended mixing of different colors. To this end, the invention performs preliminary ejection of ink after a wiping action to sweep mist adhering to a face of a printing head, in which an ejection opening is formed. Moreover, the amount of ink to be wastefully consumed by the preliminary ejection after the wiping is reduced. To this end, the number of preliminary ejections is regulated. The degree of adherence of mist to the ejection-opening-formed face depends on the amount of printing (the number of printed sheets, the number of ink ejections for printing, or the like). So, at the time of the preliminary ejection after the wiping, the number of ink ejections in the preliminary ejection is regulated in accordance with the amount of printing that has been done since the last wiping action.

  • Publication number: 20150217494
    Abstract: A molding die is devised to suppress the formation of a fragile layer, thereby ensuring stable production of a resin molded body having remarkably improved adhesion of a plating film. A plurality of stepped parts are formed so as to be spaced apart from each other on a second die surface which molds a back surface on the side opposite to a design surface to which metal plating is to be applied, along the main flowing direction of a molten resin and in a direction crossing the main flowing direction. Since the flow of the molten resin changes due to the stepped parts and the influence thereof extends even to the vicinity of the design surface, the formation of a fragile layer is suppressed.

  • Patent number: 9050794
    Abstract: An inkjet printing apparatus which performs printing by performing scanning using a print head has a problem in that quality of an image of a ruled line is degraded when ink is not ejected for a certain period of time. To address this problem, control is performed such that power for driving the print head for unit regions including pixels having a ruled-line attribute becomes higher than power for driving the print head for unit regions which do not include the pixels having the ruled-line attribute. By this, a high-quality ruled-line image may be printed.

  • Patent number: 8702192
    Abstract: This invention prevents a possible color mixing, that may occur more than a predetermined time after the wiping operation, by executing a pre-printing cleaning ejection while at the same time minimizing the amount of waste ink produced by the cleaning ejection. To this end, if a color mixing is determined as being likely to occur an elapsed time after the previous wiping operation, the pre-printing cleaning ejection uses a second ink volume U, which represents both the color mixing elimination ink volume and the ejection failure elimination ink volume. If it is decided that there is no likelihood of the color mixing occurring the elapsed time after the wiping operation, the pre-printing cleaning ejection uses the first ink volume D which represents only the ejection failure elimination ink volume.
