Abstract
A data processing apparatus, a data processing method and an inkjet printing apparatus are offered that are capable of reducing, in any kind of image, the occurrence of color unevenness while achieving a high speed output via a bi-directional printing. In order to achieve this, forward scan print ratio and backward scan print ratio with respect to a predetermined area comprising a plurality of pixels is set based on multi-value image data of the predetermined area. Next, binary print data for the forward scans and binary print data for the backward scans at the predetermined area is generated based on the multi-value image data and the set print ratios. According to such a configuration it is possible to increase the ratio of bi-directional printing with respect to areas at which color unevenness appears with difficulty, and increase the ratio of one-directional printing at areas where color unevenness appears with ease.
