摘要： There is provided an image processing apparatus in which in a case of tone-expressing one pixel corresponding to a plurality of areas (printing resolution) in a multi-pass print, it is possible to output a uniform image without graininess or density unevenness over all-tone regions from a low-density region to a high-density region. To this end, by referring to dot patterns in which a print or a non-print of dots onto each pixel (area) corresponding to a printing resolution are in advance defined, quantization data is converted into binary data having the higher printing resolution. At this time, the dot patterns are prepared to be different from each other for M times of scans in a multi-pass print of M passes. In consequence, it is possible to restrict a variation of a coverage ratio due to a printing position displacement in each printing scan.

摘要： An ink jet printing apparatus and printing method are provided that can, without the addition of a special structure, suppress density imbalance between the print images formed by ink ejected from each of the ejection ports formed on a print head. As for the plurality of ejection ports, one portion of them are established as multiple impact ejection ports that form multiply impacted pixels at which the number of times ink is impacted at the same area is greater than at other pixels of the print area. And, print control is carried out such that more multiply impacted pixels are printed at print areas printed using ejection ports at the ends of the print head than at print areas printed without using ejection ports at the ends of the print head.

摘要： Quality degradation of a print image due to a deviation amount in a landing position of ink is prevented while suppressing degradation of through-put. In a method of completing a print to a unit region by at least one reciprocal scan to the unit region of a print medium by a printing head in which plural ink ejection ports are arrayed for ejecting ink, a printing rate in a scan direction where a deviation amount in a landing position of ink in an array direction of the ink ejection ports is relatively large is set relatively low and the printing rate in the scan direction where the deviation amount in the landing position of ink in the array direction of the ink ejection ports is relatively small is set relatively high.

摘要： The order of the arrangement of ejection opening arrays of two types of ink overlapping in reciprocating scan is decided as follows. An ejection order is decided so that the case where the fixing areas of a main droplet and a satellite are different (dot area is increased) in the forward and backward scan first occurs. By this configuration, the area of the dot and the portion in which different colors are generated due to the difference in the overlapping order in the reciprocating scan can be reduced, compared with the case where the arrangement order is opposite to the above-described case. As a result, a difference in color between areas for which printing is completed by the reciprocating scanning is reduced and thus color unevenness of a printed image can be reduced.
