Printing method and printing apparatus
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 rear 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. The second print mode is a print mode that is applied to a middle area, with respect to the transport direction, of the medium. The second correction value is for correcting an ejection amount of the ink in each row region individually. The correction of the ejection amount using the combined correction value is carried out in a coexistent segment in which certain row regions and another row regions are coexistent. The certain row regions are row regions in which the dot rows are formed by the first print mode. The other row regions are row regions in which the dot rows are formed by the second print mode.
