Abstract

An image printing apparatus and method capable of preventing any smearing that occurs in printing at the same landing position using nozzles of different colors with a smaller RAM capacity are provided. For this purpose, for example, to prevent any ink smearing that occurs when K (black) ink and color ink are printed at the same landing point, K data in raster data transferred in accordance with the order of drive of the printing elements of a printing head is temporarily stored. In printing color data on the same raster, it is determined whether color data to be printed at the same landing point as that of the K data in the temporary storage area is present. If such data is present, smearing preventing processing is performed. In this way, any smearing between the K (black) ink and color ink can be prevented.
