Abstract
One or more scans used to apply a specific ink are varied according to the overlapping conditions of the specific ink and a non-specific ink, and bias in the specific ink nozzle usage frequency and bias in the printing ratio among passes is suppressed. For this purpose, one or more scans used to apply the specific ink are determined on the basis of applying amount information for the specific ink and the non-specific ink. For example, the one or more scans used to apply the specific ink are determined such that the ratio of specific ink applied by the last half of plural scans is greater for a unit pixel whose application ratio of non-specific ink to specific ink is greater than a predetermined ratio than for a unit pixel whose application ratio of non-specific ink to the specific ink is less than the predetermined ratio.
