摘要： According to the present invention, if an image is printed on both sides of a printing medium, the possibility of rubbing ink off from the printing medium is minimized to inhibit contamination of the printing medium and the interior of the printing apparatus, while maintaining the print grade of the image. Thus, if a double side print mode is executed in which an image is printed on both sides of the printing medium, then, for a particular image part, a ratio of an amount of black pigment ink used to an amount of black dye ink used is set so as to limit the amount of black pigment ink used and to compensate for a decrease in print density with the limited amount of the black pigment ink used.
摘要翻译：根据本发明，如果在打印介质的两面上打印图像，则可以最大程度地减少从打印介质上摩擦墨水的可能性，从而抑制打印介质和打印设备内部的污染，同时保持打印等级的图像。因此，如果在打印介质的两面上执行图像打印的双面打印模式，则对于特定图像部分，使用黑色颜料墨水的量与所用的黑色染料墨量的比例被设定为限制使用的黑色颜料墨水的量，并且使用有限量的黑色颜料墨水补偿印刷密度的降低。

摘要： A region for quantization having a value lower than the value B is assumed as having little influence by Bk data on the pixels in this region. Thus, in order to prioritize the optimization of the granularity at the start of the input of GY data, the LUT having a combination of GY and gy as an input as an input is used to perform separation quantization. On the other hand, since a region having a value equal to or higher than the value B requires the use of Bk data, the LUT having only a combination of Bk and GY as an input as an input is used to perform quantization. As a result, the number of types of pieces of ink data referencing the table can be 2, thus suppressing an increase in the table size.
摘要翻译：假设具有低于值B的值的量化区域被Bk数据对该区域中的像素的影响很小。因此，为了优先化GY数据输入开始时的粒度优化，将具有作为输入的GY和gy的组合的LUT用作输入，以执行分离量化。另一方面，由于具有等于或大于值B的值的区域需要使用Bk数据，所以使用仅具有作为输入的Bk和GY的组合的LUT作为输入进行量化。结果，参考该表的墨水数据的数量的数量可以为2，从而抑制了表格尺寸的增加。

摘要： In an inkjet printing method of performing printing on a printing medium by ejecting inks from a printing head configured to eject chromatic inks and an achromatic ink while moving the printing head, high-quality printing with few boundary stripes produced when the amount of inks is large is realized without complicated control being performed. To this end, print data in a boundary and the vicinity thereof is divided into unit regions, and for each unit region, performed are (A) a first reduction processing which determines a hue of the unit region based on amounts of the chromatic inks, and reduces the amount of chromatic inks applied to the unit region according to the determined hue; and (B) a second reduction processing which reduces an amount of achromatic ink based on the amount of achromatic ink applied to the unit region.

摘要： On performing a predetermined printing operation, whether or not, among a plurality of printing elements, only a part of the printing elements are applied is detected. If it is judged that only the part of the printing elements are used, a judgment is made whether or not the preliminary discharge operation is performed based on the number of discharges for the part of the printing elements, and if it is not judged that only the part of the printing elements are used, a judgment is made whether or not the preliminary discharge operation is performed based on the number of discharges for all of the printing elements of the printing head. This eliminates an unnecessary preliminary discharge for non-printing elements even in a printing operation mode in which only a part of the printing elements are applied.
摘要翻译：在执行预定打印操作时，检测在多个打印元件中是否仅施加打印元件的一部分。如果判断仅使用打印元件的一部分，则判断是否基于打印元件的一部分的放电次数进行预备放电操作，并且如果不判断仅仅是使用打印元件的一部分，基于打印头的所有打印元件的排出次数判断是否执行预备排放操作。即使在只有一部分打印元件被施加的打印操作模式中，这也消除了非打印元件的不必要的预排出。

摘要： By subtracting a first parameter related to the printing position deviation inherent to the printing head from a second parameter that is obtained by actually measuring the printing position deviation in a state where the printing head is mounted on the printing apparatus, a third parameter related to the printing position deviation inherent to the printing apparatus is acquired. When a new printing head is mounted on the printing apparatus, a new second parameter is computed from the third parameter and a first parameter that is of the new printing head. By this procedure, it is possible to hold down a time required for actual measurement of the printing position deviation and consumables, and even when the printing head is exchanged, it becomes possible to stably output a uniform image free from the printing position deviation.

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： 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。
