    摘要： When the head temperature Tfinish, which is the head temperature at the time of completion of a preceding scan, is higher than the stable ejection temperature Tstable, the target temperature is made a temperature that is only a temperature value ΔT lower than the head temperature Tfinish. On the other hand, when Tfinish, the head temperature at the time of print completion, is lower than the stable ejection temperature Tstable, the target temperature is made a temperature that is only a temperature value ΔT higher than the head temperature Tfinish. Because of this it is possible to inhibit head temperature rise in the case where an image with a high print density is printed.

    摘要翻译： 当作为前次扫描完成时的头部温度的头部温度T finish高于稳定喷射温度Tstable时，将目标温度设定为仅比头部低的温度值＆Dgr; T的温度 温度Tfinish。 另一方面，当印刷完成时的头部温度T finish低于稳定的喷射温度Tstable时，目标温度成为仅比头部温度T finish高的温度值＆Dgr; T的温度。 因此，可以在打印出高打印浓度的图像的情况下抑制头温升高。

    摘要： An inkjet printing apparatus of the present invention is equipped with a recovery device for recovering an ink ejection state of a print head. The print head has a plurality of nozzle rows each for ejecting an ink of a different color, and a nozzle surface. The recovery device performs wiping of the nozzle surface and preliminary ejection from the print head. After the wiping, an evaluation patch is created by performing the preliminary ejection onto a printing medium, and the number of preliminary ejections of a specific nozzle is increased to a number larger the number of preliminary ejections of other nozzles based on an image of the evaluation patch. It is possible to appropriately decide the number of preliminary ejections for each nozzle according to color mixture parts that vary for every apparatus.

    摘要： An ink jet printing apparatus performs printing on a print medium, and includes a print head having a plurality of ejection openings, a head temperature acquisition unit that acquires a temperature of the print head, and a heating unit configured to heat the print head. In addition, a control unit is configured to control the heating unit so as to cause a temperature of the print head to be a target temperature, at start of a print scan by the print head, and a setting unit is configured to set the target temperature. If a completion temperature acquired by the acquisition unit at a time when a previous print scan is completed is lower than a threshold temperature, the setting unit sets a temperature higher than the completion temperature as the target temperature, and if the completion temperature is equal to or higher than the threshold temperature, the setting unit sets a temperature lower than the completion temperature as the target temperature.

    摘要： A mask pattern is employed for multi-pass printing. The mask pattern is the sum of a first mask pattern, relative to a first location that includes areas wherein dots are to be printed when a density value is smaller than a predetermined value, and a second mask pattern, relative to a second location that includes areas wherein dots are to be printed only when the density value is equal to or greater than the predetermined value. Using multiple scans, up to one dot is printed in the first region, while two dots or more are printed in the second region. With this arrangement, since the first mask pattern, which greatly affects a low-duty image, and the second mask pattern, which greatly affects a high-duty image, can be independently designed, problems that occur with images prepared at individual duties can be coped with by the separate mask patterns.

    摘要： An ink ejection nozzle constituting section characterized for performing printing with a high image quality, and an ink ejection nozzle constituting section characterized for performing full-color printing at a high speed are separately disposed in one ink jet head to constitute a recovery system capable of performing suction recovery only in each of the constituting sections, and the suction recovery optimized for each constituting section is carried out. Accordingly, the size enlargement of a recording apparatus can be restrained, and total ink consumption can be suppressed at the time of maintenance.

    摘要： An ink-jet printing method, an ink-jet printing apparatus and an ink-jet printing system are proposed, which are free from the deterioration of color development effect even if a plurality of color inks are used, caused by the overlap of different color inks on a printing medium. For this purpose, when density data quantized to several ranks are converted finally to binary data by using predetermined dot arrangement patterns, a dot arrangement pattern different from those for other color inks is prepared for a particular color ink. Accordingly, it is possible to reduce as much as possible the probability in that the particular color ink is overlapped with the other inks on the printing medium, whereby the color development of the particular color ink is effectively facilitated.
