摘要： An ink-jet printer capable of reducing temperature rise of an ink-jet head to the utmost. The printer comprises a long ink-jet head in which a plurality of ink-discharge nozzles are arrayed in a lengthwise direction and a plate auxiliary member attached to the ink-jet head along the lengthwise direction. The auxiliary member has a predetermined volume to increase the thermal capacity of the ink-jet head, and has a plurality of warp correction portions provided at positions corresponding to different positions in the lengthwise direction of the ink-jet head, to provide a function to correct warp of the ink-jet head.

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： The present invention allows a high-speed printing by a print head in which nozzles are arranged with a high density to reduce eddy flow caused between the print head and a print medium, providing an image with a high quality. Thus, the present invention allows the same printing region of the print medium to be sequentially printed by the respective nozzle arrays provided in the print head in accordance with image data thinned-out by the mask pattern M, thereby completing the image by multi-pass. Then, a plurality of pieces of image printed to be printed to the same printing region at which the nozzle arrays pass in one pass are alternately thinned-out by different high and low thinning-out ratios in the direction in which the nozzles are arranged.

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： 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 ink jet printing apparatus in which satellites are produced, it is an object to minimize image impairments caused by the satellites in a variety of print modes. To this end, index patterns are prepared which have different sizes for different print modes. This enables satellites to land at print positions of main dots in other pixels in any of the print modes that have different distances between main dots and satellites. It is therefore possible to minimize image impairments caused by the satellites and to output a crisp image.
