Patent number: 9227423Abstract: In a color mode, among clear ink data CL1 and CL2, only the data CL2 is set to a uniform use amount of 20%, while the use amount for the data CL1 is set to zero. Meanwhile, in a monochrome photo mode, the data CL1 indicates a usage of 10% to 40% near a white point, but starting at the intermediate gradations the data CL1 use amount decreases while the data CL2 use amount increases, with a data CL2 use amount of 20% near a black point. In so doing, it is possible to sufficiently suppress bronzing in the color mode where coloring ink data exists, without imparting a particularly strong unnatural look except for specific colors. Meanwhile, in the monochrome photo mode where coloring ink data does not exist, high-level suppression of bronzing is possible, at the cost of a slight reduction in the glossiness of the printed material.Type: GrantFiled: April 26, 2013Date of Patent: January 5, 2016Assignee: CANON KABUSHIKI KAISHAInventors: Takeshi Yazawa, Makoto Torigoe, Hinako Ojiro, Kei Yoshizawa

Patent number: 9126403Abstract: Provided is an inkjet printing apparatus that, when performing multi-pass printing using pigmented ink and image enhancing liquid for adjusting the glossiness, is capable of outputting a high-quality image in which gloss unevenness due to displacement of the printing position cannot be noticed. In order to accomplish this, dot arrangement data is generated based on input image data so that the dot arrangement of image enhancing liquid includes a greater low-frequency component in the spatial frequency than the dot arrangement of colored ink on a print medium. As a result, it is possible to suppress gloss unevenness even when printing position displacement occurs, while at the same time suitably suppressing a feeling of graininess in colored ink.Type: GrantFiled: May 3, 2013Date of Patent: September 8, 2015Assignee: CANON KABUSHIKI KAISHAInventors: Hinako Ojiro, Makoto Torigoe, Hiroshi Tajika, Yuji Konno, Takeshi Yazawa, Hiroshi Taira
