Patent number: 7290858Abstract: The image quality deterioration due to the collection of dots of low-lightness by the preliminary ejection is prevented, in the case of performing the ink ejection for preliminary ejection during the printing onto printing paper. More specifically, the preliminary ejection pattern is set as a pattern in which the distance between a cyan dot of relatively low-lightness and a magenta dot is longer than a distance between a yellow dot of relatively high-lightness and a cyan dot nearest the yellow dot among low-lightness colors. Closely forming dots of low-lightness that would be perceived as a group of collected dots can be prevented, thereby performing printing that will not deteriorate the printing quality due to the paper preliminary ejection.Type: GrantFiled: June 13, 2005Date of Patent: November 6, 2007Assignee: Canon Kabushiki KaishaInventors: Tomomi Furuichi, Rie Takekoshi, Daigoro Kanematsu, Naoko Baba, Kazuo Suzuki, Mitsutoshi Nagamura

Patent number: 7287825Abstract: In an ink jet printer in which preliminary ejection is performed onto printing paper, unnecessary ink consumption due to the preliminary ejection is suppressed. More specifically, the paper preliminary ejection is designed to be performed only for a printing head of cyan ink. For this cyan ink the longest duration of its non-ejection state, in which the printer can attain high printing quality when restarting printing after continuation of the non-ejection state in the case of not performing the paper preliminary ejection, is shorter than 1.6 seconds of the duration which is necessary for the reciprocal printing. This eliminates the paper preliminary ejection for the printing heads of the other colors of ink, thereby avoiding unnecessary ink consumption due to the paper preliminary ejection performed uniformly for every color of ink.Type: GrantFiled: June 13, 2005Date of Patent: October 30, 2007Assignee: Canon Kabushiki KaishaInventors: Tomomi Furuichi, Rie Takekoshi, Daigoro Kanematsu, Naoko Baba, Kazuo Suzuki, Mitsutoshi Nagamura

Patent number: 7270390Abstract: In a data creating method for creating image data corresponding to each of a plurality of color inks applied to a black image area formed on the basis of image data on a black ink, with the plurality of color inks being a cyan ink, a magenta ink, and a yellow ink, an image data creating step creates image data corresponding to each of the plurality of color inks on the basis of the image data on the black ink. The image data creating step creates the image data on each of the plurality of color inks so that the rate of areas in which all the plurality of color inks are applied, in the black image area, is higher than that of areas to which only some of the plurality of color inks are applied. At least one of the cyan ink, the magenta ink, and the yellow ink contains a component that coagulates a color material of the black ink.Type: GrantFiled: February 28, 2005Date of Patent: September 18, 2007Assignee: Canon Kabushiki KaishaInventors: Naoko Baba, Daigoro Kanematsu, Kazuo Suzuki, Mitsutoshi Nagamura, Tomomi Furuichi, Rie Takekoshi

Publication number: 20050264593Abstract: A printing apparatus is provided which can utilize a power supply to its maximum capacity without overly degrading a throughput. Print area that can be printed in one scan of a print head is divided into a plurality of blocks. The number of data indicating print in each block is detected. Then the detected value is compared with a plurality of thresholds. Based on a result of the comparison, a scan speed of the print head and the number of scan are determined. This arrangement allows for a selection of an optimum printing method from among a plurality of scan speeds and a plurality of divided printing modes even when an image that may cause a current in excess of the maximum power supply capacity to flow is printed. With this printing apparatus it is possible to execute printing fully utilizing the power supply capacity without overly degrading the throughput.Type: ApplicationFiled: May 19, 2005Publication date: December 1, 2005Applicant: Canon Kabushiki KaishaInventors: Mitsutoshi Nagamura, Daigoro Kanematsu, Naoko Baba, Kazuo Suzuki, Tomomi Furuichi

Publication number: 20050195236Abstract: In an inkjet printing apparatus which performs printing on a printing medium using an inkjet printhead for discharging ink, preliminary discharge, where ink discharge irrespective of printing is performed at the time of print execution, is performed under a predetermined condition to obtain information regarding a discharge state of the printhead. 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.Type: ApplicationFiled: February 24, 2005Publication date: September 8, 2005Applicant: Canon Kabushiki KaishaInventors: Kazuo Suzuki, Daigoro Kanematsu, Rie Takekoshi, Mitsutoshi Nagamura, Naoko Baba
