摘要： A spliced ink-jet head including head chips, each of which is capable of discharging inks of two or more colors, and which are spliced in a staggered manner which restrains the occurrence of splice streaks, white streaks caused by deflection at ends or uneven colors attributable to different landing orders of ink droplets in spliced portions of different colors when one-pass recording is carried out. The head chips is arranged such that, in a relationship between two adjoining head chips, at least one discharge port of one head chip and one discharge port of the other head chip for the same color tone ink in end portions overlap on a line in a recording material feeding direction, while discharge ports for different color tone inks do not overlap.

摘要： The present invention provides an ink jet printing apparatus configured to allow the ejection performance of a print head with a large number of nozzles densely arranged therein to be kept in a favorable condition by preliminary ejection and to enable degradation of images caused by the preliminary ejection to be alleviated. Preliminary ejection data generation unit is provided which generates preliminary ejection data designed to allow ink not contributing to image printing to be ejected through nozzles 103A and 103B in a print head 21-1. The preliminary ejection data generation unit generates preliminary ejection data designed to allow the ink to be preliminarily ejected onto a print medium through the nozzles 103B, which are included in the plural types of nozzles and which offer a smaller ejection amount than the other nozzles 103A.

摘要： There is provided an inkjet printing apparatus which prints using a printhead for discharging ink by a plurality of scanning operations of the printhead including forward scanning and reverse scanning in a single area of a print medium. In the inkjet printing apparatus, the ink discharge amount is acquired for each unit area obtained by dividing the end area of the single area in the scanning direction. The acquired ink discharge amount of each unit area is compared with a predetermined threshold. The printing ratios of the plurality of scanning operations are controlled to set the printing ratio of the final scanning operation lower than the average one of the remaining scanning operations in a unit area where the ink discharge amount is larger than the predetermined threshold.

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。
