摘要： [Task] To improve the quality of an image formed by a liquid ejecting apparatus capable of performing a bi-direction printing process.[Means for Resolution] A raster (POL raster) formed by a partial overlap (POL) is formed such that pixels (first type of dots) formed upon a going movement and pixels (second type of dots) formed upon a coming movement are alternately arranged. The first type of dots and the second type of dots can be alternately formed by controlling an amount of transport of a print sheet and an amount of feed in a horizontal direction (main scanning direction) of a recording head. In this way, it is possible to alternately form the dots formed in opposing filling directions in the POL raster. By changing the allocation of the POL nozzles in an odd-numbered pass and an even-numbered pass and performing an anomalous feeding process of the print sheet, it is possible to change a combination of the POL nozzles forming the POL raster. Accordingly, since a noise occurring in the main scanning direction of an image printed on the print sheet can be restrained, it is possible to improve the quality of an image.

摘要： 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.
