摘要： After a first scan in a forward direction, conveying corresponding to one nozzle block is performed, and then in a second scan in a backward direction, printing of a “printing area 1,” which is a unit area, is completed. Then after completion of printing of the unit area, conveying corresponding to 14 nozzle blocks is performed. Then by reciprocal third and fourth scans, printing of a “printing area 2” is completed in a likewise manner. Subsequently, two scans in a reciprocal manner are performed in a likewise manner to perform printing of each unit area. In any unit area, printing time intervals between scans are such that, at a same position in a scan direction, the time interval is the same. Consequently, differences in density between unit areas that are adjacent in a conveying direction of a printing medium, that is, between-band unevenness becomes more difficult to recognize.
摘要翻译：在向前方向进行第一扫描之后，执行对应于一个喷嘴块的传送，然后在向后方向的第二扫描中完成打印作为单位区域的“打印区域1”。然后在完成打印单元区域之后，执行对应于14个喷嘴块的传送。然后通过相互的第三和第四扫描，以类似的方式完成“打印区域2”的打印。随后，以相同方式执行两次扫描以执行每个单位区域的打印。在任何单位区域中，扫描之间的打印时间间隔使得在扫描方向上的相同位置处时间间隔相同。因此，在打印介质的输送方向上相邻的单位面积之间的密度差，即带间不均匀性变得更难以识别。

摘要： An ink jet printing apparatus and an ink jet printing method are provided which are capable of minimizing image impairments caused by a bias of satellite positions even when an odd-numbered-pass bidirectional multi-pass printing is performed. To this end, in an odd-numbered-pass bidirectional printing, a mask pattern, in which print permitted pixels and print non-permitted pixels are arranged such a way that a percentage of pixels in which predetermined two inks are permitted to be printed by scans in different directions is higher than a percentage of pixels in which the predetermined two inks are permitted to be printed by scans in the same directions, is used. This increases the probability of satellites of the two types of the inks printed in the same pixels being printed on both sides of main dots, thus allowing a uniform image to be produced even by an odd-numbered-pass bidirectional printing.
摘要翻译：提供了一种喷墨打印设备和喷墨打印方法，即使当进行奇数倍双向多通打印时，也能够最小化由卫星位置的偏置引起的图像损伤。为此，在奇数次双向打印中，其中布置打印许可像素和打印非允许像素的掩模图案被布置成使得允许通过以下方式打印预定两种墨水的像素的百分比：使用不同方向的扫描高于允许通过相同方向的扫描来打印预定的两种墨水的像素的百分比。这增加了打印在主要点的两侧上的相同像素中打印的两种类型的墨水的卫星的概率，从而即使通过奇数遍双向打印也可以产生均匀的图像。

摘要： To enable the printing in which it is difficult for the dot to stand out and it is difficult for the gradation sequence properties to be degraded. Therefore, among plural dots each having a different size, the binary processing is carried out by using the same first dot arrangement pattern in regard to the large and medium-sized dots and the binary processing is carried out by using a dot arrangement pattern different from the first dot arrangement pattern in regard to the small-sized dots.
