  • Patent number: 8955955
    Abstract: An image recording method has a feature such that a first ink, a second ink, and a third ink satisfy both the following relationships (1) and (2): (1) the film thickness of dots of the inks formed when one drop of each ink is applied to the recording medium is as follows: First ink>Second ink>Third ink; and (2) the penetration time of the clear ink when applying the inks to the recording medium, and then further applying one drop of the clear ink to the region to which each ink is applied is as follows: First ink?Second ink?Third ink.
    Type: Grant

    Date of Patent: February 17, 2015
    Assignee: Canon Kabushiki Kaisha

  • Patent number: 8506068
    Abstract: There is provided an inkjet printing method of applying plural different kinds of color ink containing pigment as a coloring agent and clear ink not containing the coloring agent on a print medium to form an image thereon. An amount of the clear ink applied in a unit area of the print medium is adjusted based upon an amount of each of the plural kinds of the color ink applied in the unit area. Since the amount of the clear ink is adjusted based upon not only the amount but also the kind of the color ink applied in the unit area, the clear ink application amount to each unit area can be more appropriate to largely reduce the gloss variations.

  • Publication number: 20120038703
    Abstract: A clear ink layer is formed by a first application of the clear ink. After a film of the clear ink is formed, a second application of the clear ink is performed onto the layer thereof. Thereby, a permeation speed of the clear ink which is applied at the second time after the clear ink is applied once becomes low, and becomes a substantially uniform one in the printed matter. That is, when the clear ink is applied at the second time onto the surface of the clear ink which is once formed into the film, the clear ink permeates therein at a substantially uniform permeation speed and is fixed thereto. As a result, the clear ink which is applied at the second time does not generate unevenness since the permeation speed thereof has no difference thereon, and can form a smooth printed matter surface.
