    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： Degradation in image quality due to disturbance in landing positions of satellites is suppressed. When scanning and printing with a printing head which has a first nozzle array ejecting relatively large ejection amount of ink, a second nozzle array arranged on one side of the first nozzle array in a scan direction and a third nozzle array arranged on the other side of the first nozzle array in the scan direction, the second and third nozzle arrays ejecting a relatively small ejection amount of ink with the same color, a printing rate of one of the second and third nozzle arrays located at the front side in the scan direction is controlled lower than that of the other located at the back side.

    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： 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.

    摘要翻译： 提供了一种图像处理装置，其中在多次打印中，在对应于多个区域（打印分辨率）的一个像素的色调的情况下，可以输出均匀的图像，而不产生粒度或密度不均匀 从低密度区域到高密度区域的区域。 为此，通过参考其中预先定义与打印分辨率对应的每个像素（区域）上的点的打印或不打印的点图案，量化数据被转换为具有较高打印分辨率的二进制数据。 此时，在M次通过的多次通过打印中，对于M次扫描，点图案被准备为彼此不同。 因此，可以限制由于每次打印扫描中的打印位置偏移引起的覆盖率的变化。
