摘要： An ink jet printing apparatus which inhibits possible bleeding by thinning color data adjacent to black data and enables printing free from image quality degradation such as gradation skip is provided. Specifically, when only one pixel has color data and pixels located vertically and horizontally adjacent to that pixel have no color data, an isolated point pixel containing a color dot is detected only in that pixel. Then, the dots other than the isolated point are thinned-out. This makes it possible to inhibit possible bleeding at the boundary between a color area and a black area and to achieve proper printing with the appropriate gradation of the entire image maintained.

摘要： In an inkjet printer that prints an image by a forward scan and a backward scan of printing heads, it is determined whether or not a color unevenness occurrence value set on the basis of values of unit image data constituting image data is more than a predetermined threshold value. If the color unevenness occurrence value is less than the threshold value, data that enable a dot to be formed in a unit area corresponding to the unit image data by the forward scan and the backward scan of the printing heads are generated. If the color unevenness occurrence value is more than the threshold value, data that enable a dot to be formed in the unit area only by one of the forward scan and the backward scan of the printing heads are generated.

摘要： 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.

摘要： Even if colors are printed in the same order for each band, time difference unevenness is suppressed which results from a difference in duration from the end of the first scan until the beginning of the second scan. An ink jet printing apparatus completely prints a scan area with a width corresponding to a predetermined length of a nozzle line. The ink jet printing apparatus includes conveying means for moving the print medium, generation means for generating print data in such a manner that in the two scans for completely printing the scan area with the width corresponding to the predetermined length, a print duty for the first scan is higher than a print duty for the second scan, and print control means for carrying out the first scan in an identical direction for all the scan areas completely printed by the two scans.
