  • Patent number: 9050819
    Abstract: When recording is performed using two different types of inks, the ink discharge order is controlled in a unit region on a recording medium so that the number of pixel regions in which an ink having a relatively high pH buffer capacity in a basic region is applied later is larger than the number of pixel regions in which an ink having a relatively low pH buffer capacity in a basic region is applied later.

  • Patent number: 8783808
    Abstract: An inkjet printing device having a print head that ejects a plurality of types of inks has: an ejection unit configured to, on the basis of ejection data that scans the print head a plurality of times to eject the inks from the print head to a predetermined area of a print medium, eject the inks to print an image; wherein the inks are classified into a first ink having a relatively large contact angle and a second ink having a relatively small contact angle, and wherein the ejection data is ejection data that, if a difference in application amount between the first ink and the second ink to be ejected to the predetermined area by the ejection unit is larger than a predetermined value, increases a ratio at which an ink having a smaller application amount is ejected in last half scans among the plurality of times of scans.

  • Patent number: 8388081
    Abstract: A printing apparatus and an inkjet printing method are provided that can a high-quality image without uneven glossiness and the like, without increasing the consumption of treatment liquid. The number of times of scans for applying treatment liquid to an image formed by a group of pigment inks with a large contact angle relative to treatment liquid is made to be smaller than the number of time of scans for applying treatment liquid to an image formed by a group of pigment inks with a small contact angle relative to treatment liquid.

  • Patent number: 8356871
    Abstract: An inkjet printing apparatus includes a print head that scans a same area of a printing medium plural times and ejects plural kinds of ink and a treatment liquid thereon to form an image, and an ejection data generating unit for generating ejection data for ejecting the plural kinds of ink and the treatment liquid to each predetermined area of the printing medium in a predetermined order from the print head. The plural kinds of ink are classified in plurality based upon a minimum application amount of the treatment liquid per a predetermined area required for realizing an effect of the treatment liquid, and the ejection data generating unit generates the ejection data in such a manner as to eject the plural kinds of ink and the treatment liquid from the print head according to the order determined in accordance with the classification of the ink ejected within the predetermined area.
