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： A printing apparatus executes printing by arranging plural printheads, each including a plurality of print elements in a direction of a print width so as to obtain the print width corresponding to a width of a printing medium and conveying the printing medium in a direction perpendicular to the direction of the print width. The printing positions of part of the print elements of a first printhead in the direction of the print width overlap with part of the print elements of a second printhead in the direction of the print width. The apparatus includes a conveyor for conveying the printing medium, a mutual complementary printer performing mutual complementary printing in the overlap portion by the overlapped print elements, and a time divisional driving controller for dividing the plurality of print elements of each of the plural printheads into a plurality of blocks, with each block composed of a predetermined number of print elements, and for time-divisionally driving the predetermined number of print elements included in each block. The predetermined number differs from a number of print elements included in the overlap portion, and the time divisional driving controller controls the driving sequences of the overlapped print elements of the plural printheads to coincide with each other.

摘要： In an ink jet printing apparatus that adopts an area grayscale system using halftone elements, this invention prevents degradations of grayscale reproducibility caused by a plurality of dots pulling each other on a print medium, and thereby realize a stable grayscale and color reproducibility. To this end dots to be applied to halftone elements, whose arrangement is determined by the halftone element-based area grayscale system, are divided into a dot group for interior halftone elements and a dot group for outline halftone elements. These two dot groups are printed with a predetermined time difference between them. The subsequent dots are then drawn to the preceding dots that are not yet absorbed in the print medium. Therefore, the overall shape and grayscale level of the merged dot in each pixel become stable, allowing for reliable image processing which in turn realizes excellent grayscale and color reproducibility.

To this end dots to be applied to halftone elements, whose arrangement is determined by the halftone element-based area grayscale system, are divided into a dot group for interior halftone elements and a dot group for outline halftone elements. These two dot groups are printed with a predetermined time difference between them. The subsequent dots are then drawn to the preceding dots that are not yet absorbed in the print medium.

摘要： Graininess is suppressed while at the same time minimizing grayscale variations caused by inter-plane deviations. For this purpose, when a pixel is printed by M relative scans of a print head over a print medium or by a relative scans of M print heads over the print medium, M pieces of multivalued image data is created according to a division number or distribution ratio determined by a grayscale value of that pixel. The M pieces of multivalued image data are individually quantized and then the printing is performed according to the quantized pixel data. This process prevents dot generation delays and graininess from deteriorating in highlighted areas, thus realizing printed images highly robust against density variations.
摘要翻译：颗粒被抑制，同时最小化由平面间偏差引起的灰度变化。为此，当通过M打印介质上的打印头的相对扫描或通过打印介质上的M个打印头的相对扫描来打印像素时，根据分割数或分布创建M个多值图像数据比例由该像素的灰度值确定。 M个多值图像数据被单独量化，然后根据量化的像素数据进行打印。该过程可防止突出显示区域中的点生成延迟和颗粒度恶化，从而实现对密度变化的高度鲁棒的打印图像。

摘要： When executing the gradation lowering processing to a data area in the lower side in multi-valued print data 403, an error generated by executing the gradation lowering processing to the data area in the lower side is stored in an information storage area 901B. On the other hand, the error thus distributed and stored is used for executing the gradation lowering processing to the data area “J” (Jth line) in multi-valued print data 404 relating to the next scan. In this way the error generated when executing the gradation lowering processing to the multi-valued print data is stored, which is used at the time of executing the gradation lowering processing to the multi-valued print data relating to the next scan. Therefore, the density is stored by receiving and delivering the error between the multi-valued print data in a scan unit.
