(54) INKJET RECORDING DEVICE AND INKJET RECORDING METHOD


(57) A smooth, uniform image is produced by minimizing the occurrence of satellites of secondary color and dispersing landing positions of the satellites as uniformly as possible. For this purpose, the printing operation performed so that satellites of the two inks (cyan and magenta ink, foe example) ejected toward the same pixel are separated and landed on opposite sides of the main dots on the same pixel. This makes the distribution of satellites uniform and makes individual satellites less noticeable, maintaining the uniformity of an image.
