20110242177 | PRINTING DEFVICE, METHOD FOR CONTROLLING PRINTING DEVICE, AND COMPUTER PROGRAM - A printing device includes a nozzle row for chromatic ink comprising K nozzles and a nozzle row for achromatic ink comprising (n·K) nozzles. In a color region, an image-forming operation is performed m times in which the movement direction of the nozzle rows switches alternately between forward and reverse directions, whereby a region of the image having a predetermined width is foamed along a first direction of an image. The image-forming operation performed m times includes the image-forming operation performed once in which both of the nozzle rows for chromatic ink and for achromatic ink are used, and the image-forming operation performed (m−1) times in which only the nozzle row for chromatic ink is used. In a monochrome region, the image-forming operation is performed once in which only the nozzle row for achromatic ink is used, whereby a region of the image having a predetermined width is formed. | 10-06-2011 |
20110261099 | PRINTING DEVICE AND PRINTING METHOD - A printing device is configured to print a first band in a first pass and to print a second band in a second pass so that the second band partially overlaps the first band for from an overlap printed area. The overlap printed area is divided by a single continuous boundary line into a first area that is printed during the first pass and a second area that is printed during the second pass. The boundary line includes a first boundary line portion where a parallel line extending parallel to a sub-scanning direction crosses the boundary line from the first area into the second area and a second boundary line portion where the parallel line crosses from the second area into the first area. | 10-27-2011 |
20110261100 | PRINTING DEVICE AND PRINTING METHOD - A first pseudo band is printed, a second pseudo band is printed so as to partially overlap the first pseudo band, and the overlap printed area is divided by a single continuously boundary line into a first area first area printed by the first pseudo band, and a second area printed by the second pseudo band. | 10-27-2011 |
20120120135 | PRINT HEAD, PRINTING DEVICE, AND PRINTING METHOD - To provide a technique for largely preventing conspicuous banding from appearing in printed images, a print head is provided with three nozzle rows in which a plurality of nozzles are arrayed in a sub-scanning direction, the nozzle rows being spaced apart in a main scanning direction. In two nozzle rows among the three nozzle rows, the positions of the nozzles in the sub-scanning direction are mutually the same, and in one nozzle row among the three nozzle rows, the positions of the nozzles the sub-scanning direction lie between nozzles of the two nozzle rows in the sub-scanning direction. The three nozzle rows can eject ink of the same hue. | 05-17-2012 |
20120120152 | PRINTING DEVICE, PRINT HEAD, AND INK CARTRIDGE - There is provided a printing device for carrying out printing with ink supplied from L ink cartridges in which ink of the same hue is accommodated. The printing device includes a print head with a plurality of nozzle rows spaced apart in a main scanning direction, and includes a first nozzle group of L×a nozzle rows, in which the positions of the nozzles in the sub-scanning direction are mutually the same and which receive a supply of the ink from each of the L cartridges in sets of a rows, and a second nozzle group of L×b nozzle rows, in which the positions of the nozzles in the sub-scanning direction differ from those of the nozzles of the first nozzle row and which receive a supply of the ink from each of the L cartridges in sets of b rows. | 05-17-2012 |
20130257985 | PRINTING DEVICE AND PRINTING METHOD - A printing device which prints on a printing medium comprising: a printing head; a control section which moves the printing head in a scanning direction and relatively moves either one of the head or the printing medium in a direction which intersects the scanning direction; and a discharge control section, wherein the printing head is provided with a plurality of color nozzle rows which are arranged to line up in an intersecting direction and the plurality of nozzles, which discharge color ink of the same color, are arranged in the intersecting direction for each color nozzle row, and a black ink nozzle row which is a nozzle row, which is arranged to line up with the color nozzle rows and where black ink is discharged, and which has a black ink nozzle group of the same number as the number of rows of the color ink. | 10-03-2013 |
20130328958 | PRINTING DEVICE AND PRINTING METHOD - A printing device which prints onto a printing medium comprising: a printing head; a control section which moves the printing head in a scanning direction and relatively moves either of the head or the printing medium in a direction which intersects with the scanning direction; and a discharge control section, wherein the printing head is provided with a plurality of color nozzle rows which are arranged to line up in the intersecting direction and where a plurality of nozzles which discharge the same color of color ink are arranged in the intersecting direction for each of the color nozzles rows, and a black ink nozzle row which is a nozzle row, which is arranged to line up with the color nozzle rows and discharges black ink, and which has a black ink nozzle group of the same number as the number of rows of the color nozzles. | 12-12-2013 |
20140292866 | PRINTING DEVICE AND PRINTING METHOD - A printing device includes a required ink amount acquisition part, an ejectable amount acquisition part, and a division printing control part. The required ink amount acquisition part is configured to determine a required ink amount based on print data of a bandwidth over which ink is ejected by driving an ink head in a main scanning direction. The ejectable amount acquisition part is configured to determine an ejectable amount based on a residual amount in an ink cartridge. The division printing control part is configured to determine whether a printing for the bandwidth is performed by one time of a main scanning operation, or the printing is performed by dividing into multiple main scanning operations based on the required ink amount and the ejectable amount, and to perform the printing in accordance with the determination. | 10-02-2014 |
