Abstract

See full text

An ink jet printing apparatus and an ink jet printing method capable of suppressing the occurrence of the texture or the feeling of granularity at a joint part even in the case where a thinning ratio in a boundary region is adjusted in order to reduce a joint streak are provided. To achieve such purposes, one dot arrangement pattern is set from a plurality of dot arrangement patterns for each pixel in accordance with a gradation level and a position on a printing medium. At this time, in a pixel region located at the joint part, a second dot arrangement pattern whose number of dots is different from a first dot arrangement pattern, which is set in the pixel region located at a part other than the joint part, is arranged so that low frequency components are less than high frequency components.
