Abstract: A printing method includes determining a first correction value corresponding to a first print mode, determining a second correction value corresponding to a second print mode, and correcting an ink ejection amount of each row region individually, using a combined correction value obtained by combining the first correction value and the second correction value. The first print mode is a print mode that is applied to a front end area, with respect to a transport direction, of a medium. Dot rows are formed extending in a nozzle movement direction that is perpendicular to the transport direction, on a plurality of row regions lined up in the transport direction. The dot rows are formed by repeating a movement ejection operation of ejecting ink onto the medium while moving nozzles in the movement direction, and a transport operation of transporting the medium in the transport direction. The first correction value is for correcting an ejection amount of the ink in each row region individually.

Abstract: [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.
