摘要： There is provided a technique for suppressing the image quality of a printed image. A printing apparatus including: a first nozzle row in which nozzles ejecting dye ink of a certain color are arranged in a predetermined direction; a second nozzle row in which nozzles ejecting pigment ink of the certain color are arranged in the predetermined direction; and a control unit repeating an ejection operation of ejecting ink from the nozzles while moving the first and second nozzle rows relative to a medium in a movement direction intersecting the predetermined direction and a transport operation of moving the first and second nozzle rows relative to the medium in the predetermined direction to print an image in which a first image formed at a predetermined position on the medium by ejecting the dye ink and then ejecting the pigment ink while moving the first and second nozzle rows relative to the medium from one side to the other side of the movement direction and a second image formed at a position on the medium different from the predetermined position ejecting the pigment ink and then ejecting the dye ink while moving the first and second nozzle rows relative to the medium from the other side to the one side of the movement direction are alternately arranged in the predetermined direction and in which an end portion of the first image overlaps with an end portion of the second image.

摘要： A liquid ejecting apparatus for forming a multicolored image on a recording medium includes: a printing head (60) that has at least a first nozzle array for ejecting a liquid of a first color (Lc) having a first hue (C), a second nozzle array for ejecting a liquid of a second color (Lm) having a second hue (M), and a third nozzle array for ejecting a liquid of a third color (Y) having a third hue (Y); a head driving section that performs a main scanning for moving the printing head in a main scanning direction; a transporting section that transports the recording medium in a sub-scanning direction crossing the main scanning direction; and a dot control section that controls the head driving section and the transporting section so as to form an image on the recording medium by ejecting the liquids on the recording medium from the nozzle while repeatedly performing the main scanning for moving the printing head in the main scanning direction and a sub-scanning for transporting the recording medium in the sub-scanning direction. The dot control section controls the printing head (60) so as to alternately form a dot having the first hue (C) and a dot having the second hue (M) and form a dot having the third hue (Y) between the dot having the first hue (C) and the dot having the second hue (M), when forming one predetermined pixel constituting the image.

摘要： 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.
