Patent number: 7527345Abstract: When colored inks and a clear ink are recorded, the printing medium tends to undulate and blotting of ink can occur. Thus, it is difficult to obtain favorable picture quality under various printing conditions. To cope with this, a printing device is designed so that colored inks and a clear ink are recorded on a printing medium and an image thereby formed is controlled. The maximum recording rate for the colored inks is made lower than the maximum ink recording rate at which ink can be recorded per unit area of a printing medium. The quantities of inks are determined so that the clear ink and the colored inks are recorded on the printing medium with the maximum ink recording rate at which ink can be recorded per unit area of the printing medium taken as the limit. The image is formed with the thus determined ink quantities.Type: GrantFiled: June 16, 2004Date of Patent: May 5, 2009Assignee: Seiko Epson CorporationInventors: Takayuki Fukuda, Yoshifumi Arai

Patent number: 7381756Abstract: It is an object of the present invention to provide an ink set which has a superior effect in suppressing gloss unevenness of printed images, and which thus makes it possible to obtain images that have a uniform gloss. The present invention achieves this object by providing an ink set comprising one or more color ink compositions containing a pigment as a coloring agent and a dispersing resin that is used to disperse this pigment, and one or more clear ink compositions which contain an aqueous polymer but which contain no coloring agent, wherein the dispersing resin and the aqueous polymer belong to a common category so that the 60° specular gloss (according to JIS Z 8741) of the printed images that are formed by the abovementioned color ink compositions and/or the abovementioned clear ink composition is substantially uniform.Type: GrantFiled: January 22, 2003Date of Patent: June 3, 2008Assignee: Seiko Epson CorporationInventors: Shinichi Kato, Shuichi Kataoka, Kiyohiko Takemoto

Patent number: 7354127Abstract: Ejection of a clear-ink nozzle is inspected with ease. When forming an ejection-test pattern for a clear ink, for example, the clear ink is ejected toward a medium from a clear-ink nozzle to form the ejection-test pattern, and a color ink is ejected toward a region in which the clear ink is to adhere from at least two color-ink nozzles to form the ejection-test pattern.Type: GrantFiled: July 14, 2004Date of Patent: April 8, 2008Assignee: Seiko Epson CorporationInventor: Hironori Endo

Patent number: 7311394Abstract: A width A of the scanning area of the ink ejection orifices and a width B of the scanning area of the reacting liquid ejection orifices are respectively set as A=(n?a)×p and B=n×p, while amount of the feeding of the printing sheet during each scan corresponds to the width of the scanning area of the reacting liquid ejection orifices, that is, A=(n?a)×p. With this system, the width of the scanning area, wherein ejection of the reacting liquid precedes ejection of the ink, is made shorter by C=a×p than the width of following scanning area; the scanning area having the width C is scanned two times by the row of the ink ejection orifices, and the thinning process is applied to this area having the width C.Type: GrantFiled: May 6, 2004Date of Patent: December 25, 2007Assignee: Canon Kabushiki KaishaInventors: Takuei Ishikawa, Kazuhiro Nakajima, Koichiro Nakazawa, Katsuhiro Shirota

Patent number: 7303258Abstract: An inkjet printer that has a fixative reservoir with at least one outlet formed in a wall section that partially defines the reservoir. The printer also has a pagewidth printhead having designated nozzles for printing the ink fixative. The fixative reservoir has fluid conduits at least partially defined in the wall section exterior such that the at least one outlet is in fluid communication with the designated nozzles. Forming the reservoir and the fluid distribution conduits to the printhead in the same component reduces the assembly time and complexity.Type: GrantFiled: January 8, 2007Date of Patent: December 4, 2007Assignee: Silverbrook Research Pty LtdInventor: Kia Silverbrook
