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： 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.
摘要翻译：提供一种打印装置和打印位置对准方法，其可以正常且平滑地执行点位置调整值计算模式，而不需要用户作出决定或调整。打印用于检查打印介质的宽度的测试图案，并由光学传感器检测以确定是否可以打印点位置调整图案。在打印点位置调整图案之前，作出关于所提供的打印介质是否合适的决定。如果提供的打印介质小于为点位置调整值计算处理指定的尺寸，则打印介质在不打印点位置调整图案的情况下被排出。这消除了浪费打印介质的消耗和污染打印设备内部的可能性。

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： A liquid ejection head according to the present invention includes a single liquid supplying port to which a liquid is supplied, a plurality of liquid supplying passages having one end in communication with the liquid supplying port, a plurality of common liquid chambers that are in communication with the other ends of the liquid supplying passages, respectively, and a plurality of ejection port groups which are in communication with the common liquid chambers via liquid channels and from which liquid droplets are ejected. A cross sectional area or length of the liquid supplying passage in communication with the ejection port group having a larger sum of opening areas of the ejection ports is set smaller than that of the liquid supplying passage that is in communication with the ejection port group having a smaller sum of opening areas of the ejection ports.

摘要： In an ink jet printing apparatus using many types of inks to execute bidirectional printing, when symmetrically arranged ejection opening rows for a cyan, magenta, and yellow inks are used in the print head, one-pass bidirectional printing is executed. On the other hand, if ejection opening rows for a black ink are used in addition to the above ejection opening rows, multi-pass printing is executed so that there are a number of dots formed with one application order for the black and other color inks and the same number of dots formed with another application order for the black and other color inks. This reduces the non-uniformity of the colors attributed to the difference in application order.

摘要： If print agents used are detected by an optical sensor at different sensitivities, the present invention enables the easy setting of adjustment values for print positions resulting from these print agents. To accomplish this object, for example, the present invention substitutes and sets adjustment values for print positions resulting from cyan, light cyan, or black ink, corresponding to a high detection sensitivity, for adjustment values for print positions resulting from a light magenta, yellow, or magenta ink, corresponding to a low detection sensitivity.

摘要： For a serial color ink jet printing apparatus that forms an image using a symmetric printing head that ejects large dots and small dots, the configuration of a printing head is provided for suppressing, to the extent possible, a cyclic fluctuation in the main scanning direction. According to the present invention, individual nozzle arrays are arranged so that two nozzle arrays, i.e., a cyan nozzle array c1 and a magenta nozzle array m1, that are located nearer each other, form dots on adjacent scan lines. With this arrangement, a high quality image, having neither an uneven density nor an uneven color, can be formed when a printing head is inclined, or when a cyclic shift in printing positions occurs, depending on the position of the main scanning direction.

摘要： According to the present invention, an adjustment value applicable to the adjustment of a printing position is obtainable by reading a printing position adjustment pattern printed on a printing medium without requiring the manual operation by the operator. Furthermore, the printing position can be optimally adjusted by accurately scanning the printing position adjustment pattern. For this purpose, an optical sensor is located in the vicinity of the printing head, and the optical sensor is situated near a predetermined position side. The predetermined position side is a pinch roller side where a large restrictive force acts to the printing medium with the printing position adjustment pattern printed thereon.
