ABSTRACT:
A printing method includes: printing, on a medium, a correction pattern made of lines, the lines being formed by repeating in alternation a dot forming operation of forming dots on the medium by ejecting ink from nozzles that move in a predetermined movement direction, and a carrying operation of carrying the medium in an intersecting direction that intersects the movement direction; measuring, for each line of the correction pattern, the darkness of pixels located on a same line of the correction pattern; obtaining, for each line of the correction pattern, a correction value for correcting a darkness, in the intersecting direction, of an image to be printed based on the darkness of the pixels that has been measured; setting, for each line of the image, the correction value obtained; and forming, in the dot forming operation, dots of a corresponding line for which the correction value has been set such that the darkness of that line becomes a darkness that has been corrected based on that correction value.
