摘要： Print codes supplied from a host computer are received and analyzed to generate print data for the individual colors, and the generated print data are stored in print buffers corresponding to the colors. The print data corresponding to yellow ink with high lightness is expressed by binary data, and is printed by one dot per pixel by a single print scan. The print data corresponding to each of the remaining high-density (thick) inks is expressed by multi-valued data having a larger number of bits than the yellow data, and is printed by a plurality of print scans.

摘要： A method and an apparatus for ink jet printing use a print head including a first nozzle group for discharging a first ink, a second nozzle group for discharging a second ink and a third nozzle group for discharging a printability improving solution. The third nozzle group is displaced between the first nozzle group and the second nozzle group. The first nozzle group discharges the first ink on the printing medium based on image data to form an image, the third nozzle group discharges the printability improving solution on the image formed on the printing medium by means of another step, and the second nozzle group discharges the second ink on the image formed on the printing medium. The printability improving solution has higher penetrability into the printing medium compared to the ink.The method and apparatus can attain a clear colored, high density image without color mixing, which has high water resistance on plain paper, with a low running cost.
摘要翻译：一种用于喷墨打印的方法和装置使用包括用于排出第一墨的第一喷嘴组的打印头，用于排出第二墨的第二喷嘴组和用于排出可印刷性改进溶液的第三喷嘴组。第三喷嘴组在第一喷嘴组和第二喷嘴组之间移动。第一喷嘴组基于图像数据排出打印介质上的第一油墨以形成图像，第三喷嘴组通过另一步骤对形成在打印介质上的图像上的可印刷性改进溶液排出，并且第二喷嘴组形成在打印介质上的图像上的第二墨水。与油墨相比，可印刷性改进溶液对印刷介质的渗透性更高。该方法和装置可以获得清晰的着色，高密度图像，无色差，在普通纸上具有高耐水性，运行成本低。

摘要： In forming an image with plural recording heads corresponding to plural inks of different densities, the image data are so distributed that the image is formed with the ink of low density until the image density reaches a predetermined density level, but is formed with the inks of low and high densities when the image density exceeds the predetermined density level, and the distributed data are corrected according to the detection of temperature relating to the recording heads, whereby a desired recorded image can be obtained even in the presence of a variation in the head temperature. Also the image data are distributed in such a manner that, when the remaining amount of one of the plural inks becomes low, the recording is conducted with the remaining ink, whereby a desired image can be obtained even when the remaining amount of one of the plural inks with different densities becomes low.
摘要翻译：在形成具有对应于不同浓度的多种墨水的多个记录头的图像时，图像数据被分布成使得图像形成有低密度的墨水，直到图像浓度达到预定的浓度水平，而是形成有当图像浓度超过预定浓度水平时，低密度和高密度，并且根据与记录头相关的温度的检测校正分布数据，由此即使在存在头部变化的情况下也可以获得期望的记录图像温度。此外，图像数据以这样的方式分布，即当多个墨水中的一个的剩余量变低时，用剩余的墨水进行记录，由此即使当其中一个的剩余量具有不同密度的多种油墨变低。

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： This invention reduces an unprinted stripe occurred by edge deviation of a printhead. An inkjet printing apparatus according to this invention can execute a first printing mode in which an image is printed by scanning the printhead in a first region on the printing medium N times and scanning the printhead in a second region adjacent to the first region (N+1) times, and a second mode in which an image is printed by scanning the printhead in the first region M times and scanning the printhead in the second region (M+1) times. The width, in the conveyance direction of the printing medium, of the second region printed in the second printing mode is narrower than the width, in the conveyance direction of the printing medium, of the second region printed in the first printing mode.
