摘要： A printing apparatus that includes nozzle arrays, formed of nozzles for ejecting ink of the first to fourth ink color groups, and that scans a print medium while moving the nozzle arrays to perform printing. For printing a unit area of a print medium, where printing is to be completed by performing a plurality of scans, the printing apparatus performs a plurality of scans, and conveys, between movements, a print medium a predetermined amount, which is equivalent to the width of the unit area. Then, to perform a plurality of scans using the nozzle arrays for the first to fourth ink color groups, print data are generated, so that for the nozzle arrays that belong to two ink color groups, the nozzle array for the first ink color group is employed to eject ink into the unit area prior to the nozzle array for the second ink color group.

摘要： In order to vary a threshold value for performing an error diffusion process depending on a pixel position, a threshold value matrix configured to have pluralities of rows and columns is prepared. In this case, pieces of data in the threshold value matrix are arrayed such that average values in the respective rows and average values in the respective columns are almost the same value. If such a threshold value matrix is used to perform the error diffusion process, the dot sparseness and denseness do not occur with a period of the matrix, and therefore the pattern or sweeping phenomenon specific to the error diffusion can be suppressed.
摘要翻译：为了根据像素位置改变用于执行误差扩散处理的阈值，准备配置成具有多行和列的阈值矩阵。在这种情况下，排列阈值矩阵中的数据块，使得各列中的平均值和各列中的平均值几乎相同。如果使用这样的阈值矩阵来执行误差扩散处理，则在矩阵的周期不会发生点稀疏和密集，因此可以抑制误差扩散特有的图案或扫描现象。

摘要： When a feeding amount for multi-pass printing is changed, the purpose related to an image quality using a binary data generation pattern can still be attained by, for example, a density pattern method. Specifically, a multi-pass printing mode is identified, and a density pattern selection matrix associated with a cycle of binary data generation is selected in accordance with the selected printing mode. That is, a density pattern selection matrix employed for binary data generation using a density pattern is changed to a size corresponding to the feeding amount designated by the selected printing mode. Thereby, a phenomenon that a unit used for image processing to gain a predetermined purpose related to an image quality does not match a unit area used for a printing operation is avoided, and an image printing purpose using a binary data generation pattern can be appropriately attained.
摘要翻译：当多次通过打印的供给量发生变化时，与使用二进制数据生成模式的图像质量有关的目的仍然可以通过例如浓度图案方法来实现。具体地，识别多遍打印模式，并且根据所选择的打印模式选择与二进制数据生成的循环相关联的浓度模式选择矩阵。也就是说，将使用密度图案的二进制数据生成中使用的浓度模式选择矩阵改变为与由所选择的打印模式指定的进给量对应的尺寸。因此，避免了用于图像处理以获得与图像质量相关的预定目的的单元与用于打印操作的单位区域不匹配的现象，并且可以适当地获得使用二进制数据生成图案的图像打印目的。

摘要： An ink jet printing method is provided, in which “color banding” and “time different unevenness” are solved simultaneously, and bidirectional multi-pass printing can be achieved with a small number of multi-passes. Thus, part of a plurality of groups, which are formed by dividing a nozzle row of a print head with the number of multi-passes, is set to be in a nonuse state (or low allowable rate of printing) in a predetermined scanning direction so as to perform printing, while a mask pattern to be used in a forward scan and a backward scan is suitably changed. Therefore, it becomes possible to unify the orders of providing inks (the orders of printing), and the print timings at a plurality of print scans, between contiguous print regions, and even all over the print regions.
摘要翻译：提供了同时解决“色带”和“时间不均匀”的喷墨打印方法，并且可以以少量的多遍来实现双向多遍打印。因此，通过将打印头的喷嘴列与多次通过的数量分开而形成的多个组中的一部分被设定为在预定的扫描方向上处于非使用状态（或低的打印允许率）以便在正向扫描和反向扫描中使用的掩模图案适当地改变时执行打印。因此，可以在连续打印区域之间甚至在整个打印区域上统一在多次打印扫描中提供墨水的顺序（打印顺序）和打印定时。

摘要： In a configuration in which a printhead including a plurality of first printing elements for discharging ink droplets and a plurality of second printing elements for discharging ink droplets larger than ink droplets discharged by the first printing elements is used, the first and second plurality of printing elements are divided into multiple blocks in such a manner that the first printing elements belong to one block and the second printing elements belong to another block. The blocks are individually driven in a time-divisional manner. In the time-divisional driving, the block consisting of the plurality of first printing elements is driven first and then the block consisting of the second printing elements is driven.

摘要： An inkjet printing apparatus which performs time-divisional driving poses the following problem for at least some gray levels when halftoning control by the unit matrix is performed. More specifically, the shape of a dot cluster in each unit matrix periodically changes due to the mismatch between the unit matrix size and the unit section size of time-divisional driving. For this reason, periodical density unevenness is generated and appears as degradation of the image quality. In order to prevent degradation of the image quality, according to this invention, image data is shifted in accordance with the unit section of time-divisional driving, or the discharge timing of ink from a printhead is shifted.

摘要： Printed pages of a stably high image quality can be produced when performing printing using a recording apparatus having an elongate joint head. The recording apparatus determines whether an end of an image to be printed is included in a joint of overlapping chips. If the end of the image is included in the joint, the recording apparatus sets groups of nozzles to be used so as to use, of nozzles corresponding to the chip joint (overlapping nozzles), continuously all nozzles included in the group of nozzles of a chip, of which nozzles other than the overlapping nozzles are used.

摘要： In an inkjet printing apparatus which generates satellites droplets, problems in an image attributable to the satellites are mitigated as far as possible. For this purpose, each parameter is adjusted to satisfy a relationship such that the distance between positions of placement of a main droplet and a satellite substantially agrees with an integral multiple of the width of an index pattern. As a result, a satellite is likely to be placed in a position overlapping a dot formed by a main droplet printed in the same area of a pixel located in the vicinity of the satellite, which prevents satellites from placement blank positions where no dot should be printed. Thus, the influence of satellites is mitigated, and problems in an image attributable to satellite are reduced.
