摘要:
A printing method and a printing apparatus are achieved that can improve the quality of printed images. The printing method comprises the following steps: (a) a step of printing a correction pattern on a medium, wherein said correction pattern comprises a plurality of lines made of a plurality of dots arranged in a movement direction of nozzles, said lines being disposed in an intersecting direction that intersects with said movement direction, and is printed by alternately repeating an operation to eject ink from a plurality of said nozzles and an operation of moving said medium in said intersecting direction; (b) a step of determining for each of said lines a correction value for correcting a darkness in said intersecting direction of an image to be printed on said medium, wherein a degree of darkness correction in said correction values is determined according to a darkness of said correction pattern and a darkness of an image to be printed; and (c) a step of printing said image on said medium based on said correction values determined corresponding to each of said lines.
