ABSTRACT:
A printing method includes by printing a first area in a test pattern using a first print mode, determining a first correction value corresponding to the first print mode for each of the row regions, based on a density measurement value for each of row regions in the first area, by printing a second area in the test pattern using a second print mode for a plurality of cycles of periods that is determined by a combination of the row region and the nozzle, determining a second correction value corresponding to the second print mode for each of the row regions, based on a density measurement value for each of the row regions in the second area, and in a coexistent segment in which certain row regions and other row regions are mixed, correcting an ink ejection amount in each of the row regions using a combined correction value that is obtained as a composition of the first correction value and the second correction value.
