ABSTRACT:
In the case that a size of each liquid droplet is enlarged to such an extent that liquid droplets each having a different color come in contact with each other on a printing medium before completion of penetration into the printing medium, e.g., when the number of liquid droplets nb required for forming a black pixel and the number of liquid droplets ny required for forming a yellow pixel are "7", a maximum number of liquid droplets capable of overlapping each other at a substantially same location is limitatively determined to assume a value smaller than the numeral "7", which that is a normally employed maximum numeral with respect to at least one ink color, e.g., yellow, whereby an image can be obtained without any deterioration of quality while preventing a malfunction of color-staining from arising along the boundary between adjacent ranges each having an ink color.
