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 |
20140204140 | PRINTING DEVICE AND PRINTING METHOD - A printing device include a control section that causes the head to execute an ejection operation of forming an image forming dot for printing an image designated as a print target and a flushing dot other than the image forming dot on a printing medium, wherein the control section has an acquiring unit that acquires a prescribed parameter in printing conditions for forming the image forming dot on the printing medium, a determining unit that determines a margin area in which the flushing dot is not formed in an end portion of the printing medium based on the prescribed parameter, and an executing unit that executes the ejection operation so as not to form the flushing dot in the margin area on the printing medium. | 07-24-2014 |
20140292850 | PRINTING DEVICE AND PRINTING METHOD - In a printing device, a print medium is transferred in a sub-scanning direction, a print head is reciprocately driven in a main scanning direction, a plurality of nozzles for ejecting same color ink in the sub-scanning direction are provided on the print head to form a nozzle array, pairs of nozzle arrays of a plurality of colors are arranged in the main scanning direction so as to be in a symmetrical sequence relative to the main scanning direction, and nozzle data for ejecting the ink at each nozzle in each nozzle array is created to perform printing. The printing device includes an inclination information acquisition part configured to obtain inclination information on an inclination of the nozzle array with respect to the sub-scanning direction, and a nozzle data allocation changing part configured to change the nozzle data to be allocated for each nozzle based on the inclination information. | 10-02-2014 |
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 |
20150054866 | PRINT APPARATUS, PRINT METHOD, AND SERIAL PRINTER - A print apparatus that is configured to cause a print head provided with nozzles and a printing substrate to move relatively, eject an ink from the nozzles, and record dots onto the printing substrate includes a print control unit. The print control unit is configured to perform a control for ejecting the ink from the nozzles, and the print control unit modifies a proportion at which dots are formed adjacent to one another depending on an ejected amount of ink. | 02-26-2015 |
20150062227 | PRINT CONTROL APPARATUS, PRINT CONTROL METHOD, AND PRINT CONTROL PROGRAM - A print control apparatus is configured to control a print head adapted to discharge ink droplets of a plurality of sizes to execute printing. The print control apparatus includes a print control unit configured to acquire a gradation value of an ink color based on image data and to determine whether or not to discharge an ink droplet of one of the plurality of sizes based on the gradation value. The print control unit is configured to determine that the ink droplet to be discharged is the ink droplet of a first size or smaller when the gradation value belongs to a maximum value-side partial range including a maximum value, and to determine that the ink droplet to be discharged is only the ink droplet of the first size when the gradation value belongs to a range towards a minimum value-side than the partial range. | 03-05-2015 |
20150070419 | INKJET PRINTER AND PRINTING METHOD - An inkjet printer includes a print head, a nozzle position and a print control section. The print head includes a plurality of nozzles to eject ink. The nozzle position specifying section is configured to specify a position of a first nozzle of the plurality of nozzles that exhibits defective ejection of the ink. The print control section is configured to eject the ink from the plurality of nozzles based on image data. The print control section is configured to determine a density of second pixels, which are positioned adjacent to first pixels to be printed by the first nozzle that was specified, and a density of third pixels, which are positioned adjacent to the second pixels except the first pixels, based on the image data, and to correct to increase the density of the second pixels and to reduce the density of the third pixels. | 03-12-2015 |
20150070428 | INKJET PRINTER AND PRINTING METHOD - An inkjet printer includes a print head, a nozzle position specifying section and a print control section. The print head includes a plurality of nozzles to eject ink. The nozzle position specifying section is configured to specify a position of a first nozzle that exhibits defective ejection. The print control section is configured to print dots in a plurality of sizes. The print control section is configured to change a dot size of a dot to be printed by a second nozzle, which is positioned adjacent to the first nozzle, to a larger size than a dot size specified in an image data, and to change a dot size of a dot to be printed by a third nozzle, which is positioned adjacent to the second nozzle, to a smaller size than the dot to be printed by the second nozzle after the change. | 03-12-2015 |
