摘要： In an ink jet printing apparatus using many types of inks to execute bidirectional printing, if ejection opening rows for yellow, magenta, and cyan inks are symmetrically arranged, ejection opening rows for a black ink are arranged adjacent to the most inside ejection opening rows for the yellow ink. Thus, a difference in color between forward scanning and backward scanning is determined by a difference in coloring between the black ink and the yellow ink. In this case, a possible color drift attributed to bidirectional printing can be suppressed by selecting the inks so that the difference in coloring between the black ink and the yellow ink is smaller than that between the black ink and the other color inks.

摘要： Two print heads combined for each ink color are arranged symmetric to each other with respect to the scan direction and are used for a bidirectional printing. In producing secondary colors, image data is spread-processed by using a “diagonal arrangement” spread pattern to differentiate the ink application order at one of dots arranged in the raster direction from those of the other dots and thereby reduce color variations in the scan direction. Further, when image data has a half-tone, a “horizontal arrangement” spread pattern, different from the previous one, is used to perform image processing on the image data to alleviate an undesired texture. To prevent a driving load from concentrating on only one of the paired print heads, the number of times that each nozzle is driven is counted and an adjustment is made to spread the frequency of use among the two paired print heads.
摘要翻译：对于每种墨水颜色组合的两个打印头相对于扫描方向彼此对称布置，并用于双向打印。在生成二次色时，通过使用“对角排列”展开图案来对图像数据进行扩展处理，以便在光栅方向上排列的一个点与其他点的点之间的墨水应用顺序区别开，从而减少扫描方向的颜色变化。此外，当图像数据具有半色调时，使用与前一个不同的“水平排列”扩展图案来对图像数据执行图像处理以减轻不期望的纹理。为了防止驱动负载仅集中在一个打印头中的一个上，对每个喷嘴的驱动次数进行计数，并且进行调整以扩展两个成对的打印头之间的使用频率。

摘要： Printing can be properly performed on a print medium other than print media preset in accordance with print modes of a printer. Specifically, when the print medium other than the print media preset in accordance with the print modes is used, patches are printed on the print medium in each combination of the ink ejection amount and the number of passes, and information regarding each evaluation of granularity and banding based on colorimetry of the patches is obtained for each combination of the ink ejection amount and the number of passes. Next, a combination of the maximum ink ejection amount and the maximum number of passes is selected from the combinations that each evaluation of the granularity and the banding satisfies a certain level. Then, a print mode having a combination nearest the combination is selected from the plurality of print modes.
