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： Multi-pass recording is executed for each of n types of super cell regions that are each defined as a region that contains pixel positions in which recording of dots is performed in various types of main scan passes of n types of main scan passes. The n types of super cell regions (i) include a boundary portion that is not parallel to either a main scanning direction or a sub-scanning direction in at least a portion of a boundary of the individual super cell regions, and (ii) are arranged such that the boundary of the n types of super cell regions appears periodically repeating along both the main scanning direction and the sub-scanning direction.
