Abstract

Disclosed is an ink jet printing apparatus and an ink jet printing method whereby the occurrence of smearing and boundary bleeding can be prevented, and high quality images, such as black characters, can be printed. According to the present invention, in high black duty matrix detection processing, a printing area wherein black dots are to be formed at a comparatively high duty is detected, and in adjacent color matrix detection processing, a printing area wherein color dot is to be formed and an adjacent printing area adjacent to the printing area are detected. Based on the detection information, data for providing color dot is generated.
