Publication number: 20150036187Abstract: A printing control apparatus for controlling printing on a lenticular sheet includes a printing control section that generates printing data corresponding to an area included in the lenticular sheet as well as another printing data corresponding to at least one area extending outward from an edge of the lenticular sheet, and that performs printing by using the printing data and the another printing data. The printing data and the another printing data are composed of a plurality of pixels, and for the another printing data corresponding to the outer area than the edge, when a row of pixels being included in the plurality of pixels and aligning so as to correspond to a long-direction of a lenticular lens is defined as a pixel row, the printing control apparatus performs thinning-out processing by handling a predetermined number of the pixel row as unit of the thinning-out processing.Type: ApplicationFiled: July 30, 2014Publication date: February 5, 2015Inventors: Mai KUBOTA, Naoki SUDO

Patent number: 8777354Abstract: A method for manufacturing a printing device, wherein the printing device uses ink including pigment ink and dye ink to form a printed image on a print medium, and discharges an ink quantity according to a voltage value of a drive voltage to form ink dots on the print medium. In this printing device, the voltage value of the drive voltage for creating ink dots is corrected.Type: GrantFiled: April 19, 2011Date of Patent: July 15, 2014Assignee: Seiko Epson CorporationInventors: Mai Kubota, Naoki Sudo, Akito Sato

Patent number: 8672438Abstract: A printing device performs band printing during two-way printing, wherein the band printing uses black pigment ink and dye ink. In this printing device, in an advancing printed area for which a print head moves in an advancing direction, pigment ink dots are formed first and dye ink dots are formed second. In a retreating printed area for which the print head moves in a retreating direction, dye ink dots are formed first and pigment ink dots are formed second.Type: GrantFiled: May 18, 2011Date of Patent: March 18, 2014Assignee: Seiko Epson CorporationInventors: Naoki Sudo, Mai Kubota, Akito Sato

Patent number: 8465117Abstract: A fluid ejecting apparatus includes a head that is provided with a first-nozzle-row and a second-nozzle-row, a platen that is provided with a plurality of convex-portions, and a control unit repeats an operation of ejecting fluid from the nozzles moving in two directions of a forward-path and a backward-path. The control unit adjusts the ejecting time such that, at the medium of the convex-portions, an amount-of-deviation in the movement-direction of the dots formed on the forward-path and the backward-path by the first-nozzle-row is less than an amount-of-deviation of the dots formed on the forward-path and backward-path by the second-nozzle-row. In the ejection operation, and such that the position in the movement-direction of the dots formed by the second-nozzle-row is a position opposite to the side on which the head moves in the movement-direction with respect to the position in the movement-direction of the dots formed by the first-nozzle-row.Type: GrantFiled: January 19, 2011Date of Patent: June 18, 2013Assignee: Seiko Epson CorporationInventors: Akito Sato, Tomohiro Yuda, Takahide Miyashita, Naoki Sudo, Mai Kubota, Bunji Ishimoto

Patent number: 8303063Abstract: A printing apparatus including a first nozzle that ejects dye ink; a second nozzle that ejects pigment ink of a color that is the same as the dye ink; and a controller that controls ejection of ink from the first nozzle and the second nozzle. The controller performs a first ejection operation, in which the pigment ink is ejected from the second nozzle after the dye ink is ejected from the first nozzle, for a predetermined position on a medium and performs a second ejection operation, in which the dye ink is ejected from the first nozzle after the pigment ink is ejected from the second nozzle, for a second position on the medium. An amount of the pigment ink per unit area that is ejected in the second ejection operation is made smaller than an amount of the pigment ink per the unit area in the first ejection operation.Type: GrantFiled: July 12, 2010Date of Patent: November 6, 2012Assignee: Seiko Epson CorporationInventors: Mai Kubota, Bunji Ishimoto, Akito Sato, Tomohiro Yuda, Naoki Sudo, Takahide Miyashita
