摘要： A present invention reduces the generation of periodic uneven print density in the image in a main scanning direction. The present invention focuses attention on a fact that, when a printing head including a plurality of nozzle arrays for ejecting different inks is used to print an image and when the same pixel is printed by a combination of nozzle arrays in which an interval in the main scanning direction is relatively short, the displacement of ink impact positions is smaller when compared to a case where the same pixel is printed by a combination of nozzle arrays in which an interval in the main scanning direction is relatively long. Thus, a dot arrangement pattern allocated to the pixel data is selected so that the same pixel is printed by a combination of nozzle arrays in which an interval in the main scanning direction is relatively short.
摘要翻译：本发明减少了主扫描方向上的图像周期性不均匀印刷浓度的产生。本发明着眼于以下事实：当使用包括用于喷射不同油墨的多个喷嘴阵列的打印头来打印图像时，并且当通过喷嘴阵列的组合打印相同的像素时，其中主要的间隔扫描方向相对较短时，与通过主扫描方向的间隔相对较长的喷嘴阵列的组合来打印相同像素的情况相比，墨水冲击位置的位移更小。因此，选择分配给像素数据的点布置图案，使得通过主扫描方向的间隔相对较短的喷嘴阵列的组合来打印相同的像素。

摘要： An ink-jet recording apparatus applicable for two-side recording, which permits reliable reduction of smears caused by contact of the recording medium or secondary smears staining the following recording media by the ink adhering in the conveyance path, and obtaining high-quality images. After performing recording on the surface of the recording medium by the recording head for discharging ink, the recording medium is reversed for recording on the back thereof. For each of unit regions obtained by dividing the region corresponding to the surface of the recording medium, information about the quantity of ink to be applied to these unit regions is acquired, and the length of the operation downtime corresponding to the period of time from the end of the operation relating to recording on the surface of the recording medium up to the operation start relating to recording on the back of the recording medium is determined based on the acquired information.

摘要： In a printer, when difference in ejection characteristic among nozzles appears as density non-uniformity and the way of letting the density non-uniformity appear is different depending upon kind of image, proper density correction is performed. Specifically, the kind of image to be printed is judged, and when the kind of image is a halftone image according to the judgment, a density correction table corresponding to the halftone image is selected and used to perform the density correction. Also when the kind of image is judged to be a solid image (without a portion of the halftone image), a proper table is selected similarly and used to perform the density correction.

摘要： In an inkjet printing apparatus having a plurality of printing modes with different scanning speeds, first and second preliminary discharge performing positions are provided within the moving area of a carriage as positions where preliminary discharge is performed to cause a printhead to discharge ink irrespective of printing, and a combination of positions where preliminary discharge is performed is set from the first and second preliminary discharge performing positions in accordance with the scanning speed in a set printing mode. This makes it possible to execute preliminary discharge at intervals within necessary intervals even if the scanning speed is decreased when high resolution printing is performed.

摘要： A printing apparatus and a print position aligning method are provided which can execute a dot position adjust value calculation mode normally and smoothly without requiring the user to make decisions or adjustments. A test pattern to check the width of a print medium is printed and is detected by an optical sensor to decide whether or not a dot position adjustment pattern can be printed. Before the dot position adjustment pattern is printed, a decision is made as to whether the print medium supplied is appropriate or not. If the print medium supplied is smaller than a size specified for the dot position adjust value calculation processing, the print medium is discharged without being printed with the dot position adjustment pattern. This eliminates a possibility of a wasteful consumption of print mediums and of contaminating the interior of the printing apparatus.

摘要： The present invention provides a liquid application device and an inkjet recording apparatus, which are capable of supplying liquid to a liquid room with the power consumption and/or the noise which are reduced. A pump is driven to fill a liquid retention space S with an application liquid. When the filling has been completed, the pump is stopped. Subsequently, the application liquid is applied to an application medium which has been transferred. At this time, a count in a RAM is increased. Thereafter, the determination as to whether or not the application can be carried out is made on the basis of the count and the prescribed application-performable number of sheets stored in a ROM. If it is determined that the application cannot be carried out, the filling of the application liquid is performed. If it is determined that the application can be carried out, next application is performed.

摘要： In an ink jet printing apparatus using many types of inks to execute bidirectional printing, if ejection opening rows for yellow, magenta, and cyan inks are symmetrically arranged, ejection opening rows for a black ink are arranged adjacent to the most inside ejection opening rows for the yellow ink. Thus, a difference in color between forward scanning and backward scanning is determined by a difference in coloring between the black ink and the yellow ink. In this case, a possible color drift attributed to bidirectional printing can be suppressed by selecting the inks so that the difference in coloring between the black ink and the yellow ink is smaller than that between the black ink and the other color inks.
摘要翻译：在使用多种类型的墨水进行双向打印的喷墨打印装置中，如果用于黄色，品红色和青色墨水的排出开口行对称地布置，则用于黑色墨水的排出开口排布置成与最内侧的排出开口行相邻，黄色墨水。因此，通过黑色墨水和黄色墨水之间的着色差异来确定正向扫描和反向扫描之间的颜色差异。在这种情况下，通过选择墨水可以抑制归因于双向印刷的可能的颜色漂移，使得黑色墨水和黄色墨水之间的着色差异小于黑色墨水和其它颜色墨水之间的着色差异。

摘要： Two print heads combined for each ink color are arranged symmetric to each other with respect to the scan direction and are used for a bidirectional printing. In producing secondary colors, image data is spread-processed by using a “diagonal arrangement” spread pattern to differentiate the ink application order at one of dots arranged in the raster direction from those of the other dots and thereby reduce color variations in the scan direction. Further, when image data has a half-tone, a “horizontal arrangement” spread pattern, different from the previous one, is used to perform image processing on the image data to alleviate an undesired texture. To prevent a driving load from concentrating on only one of the paired print heads, the number of times that each nozzle is driven is counted and an adjustment is made to spread the frequency of use among the two paired print heads.
摘要翻译：对于每种墨水颜色组合的两个打印头相对于扫描方向彼此对称布置，并用于双向打印。在生成二次色时，通过使用“对角排列”展开图案来对图像数据进行扩展处理，以便在光栅方向上排列的一个点与其他点的点之间的墨水应用顺序区别开，从而减少扫描方向的颜色变化。此外，当图像数据具有半色调时，使用与前一个不同的“水平排列”扩展图案来对图像数据执行图像处理以减轻不期望的纹理。为了防止驱动负载仅集中在一个打印头中的一个上，对每个喷嘴的驱动次数进行计数，并且进行调整以扩展两个成对的打印头之间的使用频率。
