20080246791 | INKJET PRINTING APPARATUS AND INKJET PRINTING METHOD - One or more scans used to apply a specific ink are varied according to the overlapping conditions of the specific ink and a non-specific ink, and bias in the specific ink nozzle usage frequency and bias in the printing ratio among passes is suppressed. For this purpose, one or more scans used to apply the specific ink are determined on the basis of applying amount information for the specific ink and the non-specific ink. For example, the one or more scans used to apply the specific ink are determined such that the ratio of specific ink applied by the last half of plural scans is greater for a unit pixel whose application ratio of non-specific ink to specific ink is greater than a predetermined ratio than for a unit pixel whose application ratio of non-specific ink to the specific ink is less than the predetermined ratio. | 10-09-2008 |

Based on the obtained information, an execution condition of the preliminary discharge is controlled. By virtue of this control, an execution condition (parameter) of the preliminary discharge can appropriately be controlled in accordance with the discharge state of the printhead, in which the ink drying state and the increased viscosity state of ink vary depending on individual differences, usage environment, usage histories (durability) and so on. | 07-02-2009 |

For achieving this object, the present invention includes a treatment liquid ejection data generating unit configured to generate the treatment liquid ejection data for ejecting the treatment liquid from the print head to the unit area before the formation of the image by the ink starts. The treatment liquid ejection data generating unit generates the treatment liquid ejection data in such a manner as to eject the treatment liquid at the plural times of the scans of the print head. | 12-30-2010 |

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. | 12-30-2010 |
20110141502 | IMAGE PROCESSOR AND IMAGE PROCESSING METHOD - 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. | 06-16-2011 |
20110189396 | INK, INK CARTRIDGE, INK-JET RECORDING METHOD, AND INK SET - 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. | 08-04-2011 |

For this, a first application step is provided that prints clear ink during the printing of the image on the print medium using color ink, or after the printing step has been completed, and after taking time for the applied clear ink to fix, a second application step is provided that prints clear ink again. Accordingly, raised portions are formed by the clear ink drops applied at the second application step, on the uniform layer of clear ink formed at the first application step, and it is possible to cause light of various wavelengths (colors) to be included in the light reflected off of the print object. | 09-01-2011 |
20110216110 | DATA GENERATING APPARATUS, INK-JET PRINTING APPARATUS, AND DATA GENERATING METHOD - Processing liquid is ejected by a scan which is as prior as possible to the ink if it is determined that the printing duty of the ink is relatively low. Furthermore, the processing liquid is ejected by a scan which is as posterior as possible to the ink if it is determined that the printing duty of the ink is relatively high. Accordingly, the change of the glossiness can be suppressed regardless of the change of the printing duty of the ink. At the same time, it becomes possible to adjust the glossiness with a minimum necessary amount of processing liquid since the glossiness is adjusted not by varying the amount of the processing liquid depending on the printing duty of the ink, but by varying the printing order. | 09-08-2011 |
