  • Publication number: 20120249678
    Abstract: Gradation data for each color to be input to a recording apparatus includes dot-recording-position information for every unit pixel and information for determining a nozzle position in a recording head for recording a dot. The information for determining the nozzle position makes determination in accordance with image data of an ink with resin and image data of an ink without resin. In a region where the ink with resin and the ink without resin overlap with each other, the ink without resin can land first.

  • Publication number: 20120154468
    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.

  • Publication number: 20110189396
    Abstract: An ink containing a plurality of coloring materials having different hues, wherein the bronze value B, which is calculated from tristimulus values of reflected light, of illumination in the direction of an angle of 45 degrees to a normal to the image, in the direction of specular reflection and tristimulus values of illumination light under the same condition of the illumination by using Formula 1, with respect to a predetermined recorded image recorded by the above-described ink is 2.0 or less.

  • Publication number: 20110141502
    Abstract: An image processor and an image processing method are provided which can suppress both a bronzing phenomenon and a color rolling in an inkjet printing apparatus and produce high-quality monochrome pictures. To that end, a monochrome image is processed by generating the multivalued density data for a chromatic ink having a hue component opposite that of the achromatic ink in a low to medium density region and, in a high density region, generating the multivalued density data for a chromatic ink having a reflection light with a hue component opposite that of a reflection light of the achromatic ink. With this arrangement, a high-quality monochrome image can be produced which has hardly noticeable hue deviations and bronzing phenomenon in the entire density grayscale or density range.

  • Publication number: 20100328389
    Abstract: The present invention has an object of providing an inkjet printing apparatus which can improve image performance while restricting an ink consumption amount of a treatment liquid. The present invention generates ejection data for ejecting the plural kinds of the ink and the treatment liquid to each predetermined area of a printing medium in a predetermined order from the print head. The plural kinds of the ink is 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. Ejection data generating unit generates the ejection data in such a manner as to eject the plural kinds of the 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.
