摘要： An inkjet printing device uses a print head including a first nozzle array for ink ejection and a second nozzle array for ejection of an image quality improvement liquid (CL), and the device prints an image on a print medium by repeating a print scan. The inkjet printing device includes a first controller for, during a first print scan, allowing nozzles on an upstream side of the first nozzle array in the conveying direction to eject the ink, and a second controller for, during the first print scan, allowing nozzles on an upstream side of the second nozzle array in the conveying direction to eject the liquid (CL) into an ink ejection area. In aaddition, a third controller, during a second print scan after the first print scan, allows nozzles on a downstream side of the second nozzle array in the conveying direction to eject the liquid (CL) into the ink ejection area.

摘要： The first print data indicating the discharging amounts of color and clear inks is generated in correspondence with an image to be printed with the color and clear inks. The second print data for designating a region for expressing decoration is generated. The discharging amount of the clear ink in the region for expressing decoration in the first print data is changed based on the second print data. Printing is done by scanning a printhead a plurality of number of times based on the changed first print data to execute the print scan of the clear ink after that of the color ink.

摘要： Performed is conveying-error correction in accordance with the kind and the number of rollers that are actually involved in the conveying of a printing medium. Each of the rollers that are potentially involved in the conveying of the printing medium has a unique amount of eccentricity, and may affect the quality of image to be printed in a peculiar manner. To address this problem, a surface of the printing medium is divided into areas according to the number and the combination of the rollers that are actually involved in the conveying. A pattern each is printed for each of the areas thus formed while the pattern enables the detection of the conveying error. A correction value to correct the conveying error is calculated using each of the patterns. The correction values thus obtained are reflected in the conveying of the printing medium.

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： The present invention allows for creating high quality images by coping with a variety of kinds of print mediums without having to prepare large-sized, large-capacity power supply and ink supply source. For this purpose, this invention detects the number of printing elements to be driven in a predetermined check area set in one scan area of the print head. If the detected value is greater than a predetermined threshold, either the number of printing elements to be driven in one scan period of the print head or one scan period from when the print head starts the printing scan until the next printing scan is started is selected and changed according to the set printing condition and the printing operation is performed accordingly.

摘要： The present invention provides an ink jet printing apparatus and a method for controlling an ink jet printing apparatus which, during a non-print operation excluding a print operation, can stir ink at a required time and to a required level according to the state of the ink in the ink tank. During a non-print operation excluding a print operation accompanied by a reciprocal movement of the carriage, a stir operation is executed to stir the ink in the ink tank by reciprocating the carriage according to a stir mode. As the stir mode, one of different modes is set according to an elapsed time from the previous stir operation.

摘要： A recording apparatus is configured to record an image on a recording medium by repeating a recording operation and a conveying operation. The recording operation is operative to apply a recording agent to the recording medium using a recording head while moving the recording head for scanning in a direction different from a predetermined direction. The recording head includes a plurality of recording elements arranged in the predetermined direction and adapted to apply the recording agent. The conveying operation is operative to convey the recording medium in a direction transverse to the scanning direction. The recording apparatus includes a recording control unit configured to perform the recording operation such that a number of the recording elements which are used to record an image on at least one of a front end portion and a rear end portion of the recording medium is reduced at a rate as compared to that of the recording elements which are used to record an image on a central portion of the recording medium, and a recording mode selecting unit configured to select a recording mode from a plurality of recording modes differing from one another in at least one of recording quality and recording time. The recording control unit changes the rate of reduction according to the recording mode selected by the recording mode selecting unit.
