Abstract
On the basis of an image data for one line, ejection data is established distributed ejection data in a period of two pixels for each scan for performing printing by scanning twice with different ejection openings. Then, a processing liquid data is generated with a processing liquid mask of a period of three pixels which is prime to the period of two pixels, with respect to the ejection data. By this, with respect to results of a first scan and a second scan, pixels, on which an ink and a processing liquid are overlaid can be distributed uniformly. As a result, it is never differentiate order of application of the processing liquid by performing printing in the order of second scan and the first scan in other scanning region from correspondence of the ejection openings.
