    • 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.
    • 根据特定墨水和非特定墨水的重叠条件,用于施加特定墨水的一次或多次扫描被改变,并且抑制了特定墨水喷嘴使用频率中的偏压和通过之间的打印比率的偏差。 为此,基于特定油墨和非特定油墨的施加量信息来确定用于施加特定油墨的一次或多次扫描。 例如,用于施加特定墨水的一次或多次扫描被确定为使得对于非特定墨水与特定墨水的应用比例更大的单位像素,多次扫描的后半部分所施加的特定墨水的比率更大 比预定比例,其比非特定墨水与特定墨水的应用比例小于预定比率的单位像素。
