Patent number: 8388081Abstract: 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.Type: GrantFiled: July 7, 2011Date of Patent: March 5, 2013Assignee: Canon Kabushiki KaishaInventors: Rie Takekoshi, Yumi Kamimura

Patent number: 8356871Abstract: 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.Type: GrantFiled: June 18, 2010Date of Patent: January 22, 2013Assignee: Canon Kabushiki KaishaInventors: Noboru Kunimine, Rie Takekoshi, Takumi Kaneko, Takao Ogata, Kazuki Narumi, Yumi Kamimura

Publication number: 20100328389Abstract: 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.Type: ApplicationFiled: June 18, 2010Publication date: December 30, 2010Applicant: CANON KABUSHIKI KAISHAInventors: Noboru Kunimine, Rie Takekoshi, Takumi Kaneko, Takao Ogata, Kazuki Narumi, Yumi Kamimura
