<p>In the present invention, a processing liquid and an ink are ejected so that ejected regions (2001 to 2004) of the processing liquid ejected in each scan by a printing head and image regions (1001 to 1004) printed by black (Bk) ink printed in each scan are mutually shifted in an auxiliary scanning direction (A). By this, when ejection of the processing liquid is to be performed in each scan, the image region of the Bk ink ejected on the processing liquid in the preceding scan is offset from a boundary of the region, to which the processing liquid is to be ejected. Therefore, overlapping of the processing liquid on the portion where the Bk ink and the processing liquid are overlap in the preceding scan, can be avoided. Accordingly, when printing is performed by ejecting the ink and the processing liquid which makes a coloring agent in the ink insoluble, drop-out of color due to overlap of the processing liquid in the joint portion of the image formed in each scan by the printing head can be eliminated. <IMAGE></p> |
