  • Publication number: 20140285704
    Abstract: The optical filter includes a filter edge portion forming a boundary between a region through which a light flux is transmitted and a region through which the light flux is not transmitted. The filter edge portion has a concavo-convex shape whose edge outline is formed by a continuous curved line including convex portions and concave portions alternately arranged in a direction in which the boundary extends. The curved line includes part satisfying ?a?60°. ?a represents an angle formed by a tangent at an arbitrary point on the curved line between a top point of one convex portion and a bottom point of one concave portion adjacent to the one convex portion with a tangent at the top point of the one convex portion, the angle ?a becoming larger as the arbitrary point becomes farther from the top point.

  • Publication number: 20140218440
    Abstract: An embodiment of the present invention provides a wiping method capable of preventing a problem such as color mixing or a discharge failure in a wiping operation during the reciprocating motion of a carriage. According to the embodiment, one or a plurality of orifice arrays out of a plurality of orifice arrays included in a printhead are wiped by making a sheet-like wiping member contact to the orifice surface of the printhead. After that, the wiping member is separated from the orifice surface of the printhead, and the used wiping member is wound. Then, the wiping member is made to contact to the orifice surface of the printhead again, and the next one or more orifice arrays are wiped.

  • Patent number: 8757753
    Abstract: The present invention has an object to provide an inkjet printing apparatus that can realize both high quality image formation and improvement of a device life caused by the reduction of a mist amount of a processing liquid. The present invention is provided with a control unit that can independently control an ink ejection condition in an ink ejection unit and a processing-liquid ejection condition in a processing-liquid ejection unit. The control unit controls the ejection condition in each ejection unit so that the mist amount of the processing liquid ejected from the processing-liquid eject unit is smaller than that of the ink ejected from the ink eject unit.

  • 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.

  • Patent number: 8665520
    Abstract: A spectral reflectance in the entire visible wavelength range may be decreased to decrease inconveniences in an image such as flare or ghost. A non-reflective periodic layer including a large number of fine uneven periodic structure bodies is formed on a substrate, and a neutral density (“ND”) film is formed on the other surface of the substrate by vacuum deposition, to improve an anti-reflection function. Regarding a beam entering the ND filter, the MgF2 film of the formed ND film suppresses the spectral reflectance at the boundary of the atmosphere and the ND film and at the boundary of the ND film and the substrate. The non-reflective periodic layer decreases the reflectance at the boundary of the substrate and the atmosphere.

  • Patent number: 8628163
    Abstract: An object of the present invention is to provide a printing apparatus and a printing method even with a variation in the temperature of a print head, thus keeping the quality of images resulting from printing high. Adjustment patterns used to adjust the difference in ink ejection timing between ink ejected in a forward direction and ink ejected in a backward direction during scanning are printed at a plurality of different temperatures. Adjustment values for the ink ejection timing at the respective temperatures are selected from the adjustment patterns. Then, the correction value for the ink ejection timing is calculated from the adjustment values based on the temperature detected by the detection device. Printing is then performed with the difference in ink ejection timing between the ink ejected in the forward direction and the ink ejected in the backward direction during scanning, adjusted based on the correction value.

  • Patent number: 8613492
    Abstract: In an inkjet apparatus using an inkjet head ejecting multiple types of inks different in viscosity after evaporation of solvent, a replacement timing for a component is judged by using a consumption amount of each type of ink and a generation rate in amount of ink droplets. Accordingly, in the case of using a large amount of ink strongly susceptible to fixed adhesion and increase in viscosity, the component is replaced at an earlier timing, which prevents fixed adhesion from influencing the print performance and the printing apparatus main body. By contrast, in the case of using a large amount of ink less susceptible to fixed adhesion and increase in viscosity, the component is replaced at a later timing and thus can be used until reaching its lifetime.
