摘要： A controller controls printing heads to print a page information mark with black ink to perform line flushing. The printing heads each have a plurality of inkjet nozzles for discharging ink being disposed in parallel in a width direction of web paper. Upon printing the mark, when an overlap region is present in which a mark printable region overlaps a line flushing region with ink other than the black ink, the controller performs control to decrease an ink discharge amount per unit area in the overlap region in the mark printable region to be smaller than that in the mark printable region except for the overlap region and the line flushing region. This causes a decreased total ink discharge amount in the overlap region.

摘要： When a printing interruption cause occurs during printing of an image on a printing medium, printing of a page being printed is completed, and further only a position mark is printed on a printing resumption page. Then, a printing unit is stopped, and a conveyance speed is decelerated to stop conveyance of the printing medium. Next, the printing medium is rewound so that printing is resumed from the printing resumption page. Thereafter, the conveyance speed is accelerated to a predetermined speed, and printing is resumed from the printing resumption page on which the position mark is printed.

摘要： After printing based on each job is ended, a printing control unit controls an operation of a printing unit so that an inspection pattern is printed on a print sheet in a period during which a conveyance control unit is keeping a conveyance speed of a print sheet at a constant speed. A maintenance content determination unit determines a maintenance content for the printing unit on the basis of an inspection result obtained by inspecting a print image for the inspection pattern. The printing control unit controls operations of the printing unit and a cleaning mechanism depending on the maintenance content determined by the maintenance content determination unit.

摘要： A printing system is provided with a dummy data insertion unit configured to insert dummy data into print data based on waiting time occurring when post-processing is performed by a post-processing device (for example, a collating machine). In a printing unit, a dummy page is printed on the basis of the dummy data. A dummy page removing unit configured to remove a dummy page from printed printing paper so that the dummy page is not supplied to the post-processing device is provided between the printing device and the post-processing device.

摘要： At least one of an upstream drive roller and a downstream drive roller is operated, after printing on web paper and at a time of transportation halt of the web paper, to make a tension value of the web paper between the upstream drive roller and downstream drive roller lower than a tension value at a time of transporting the web paper, so that at least part of contact portions of the web paper in contact with five cooling rollers separate from the five cooling rollers. Consequently, gaps can be produced between the contact portions of the web paper in contact with the five cooling rollers and the five cooling rollers. This can reduce waterdrops due to dew condensation adhering to the web paper. As a result, paper break can be inhibited at a time of starting transportation of the web paper.

摘要翻译： 控制器控制打印头以黑色墨水打印页面信息标记以执行线路冲洗。 打印头各自具有多个喷墨喷嘴，用于排出在卷筒纸的宽度方向上平行布置的油墨。 在打印标记时，当存在可打印区域与墨黑色墨水以外的标记可打印区域与线冲洗区域重叠的重叠区域时，控制器执行控制以降低标记中的重叠区域中的每单位面积的墨水排出量 可打印区域比除了重叠区域和线冲洗区域之外的标记可打印区域中的可打印区域小。 这导致重叠区域中的总墨水排出量减少。

摘要： A printing apparatus includes: a mechanism transporting a print medium; a first sensor outputting a signal indicating the presence or absence of a first mark; a first determining unit determining, on a first surface, a position of a second mark and a print position of an image based on the output signal; a first print head printing the second mark and the image at the determined print positions; a second sensor outputting a signal indicating the presence or absence of the first and second marks; a second determining unit locating a position of a predetermined one of the first and second marks, based on the signal output from the second sensor, and determines, on a second surface of the print medium, a print position of a target image based on the located position of the predetermined mark; and a second print head printing the target image at the determined print position.

摘要： After printing cue marks and front surface images on the front surface of web paper by a printing station, an image data elongation-contraction processor creates corrected back surface image data based on elasticity information, and a printing station prints back surface images based on the corrected back surface image data, on the back surface of the printing medium. At this time, a page interval calculator calculates a page interval from an interval between the cue marks detected by a detector, and a difference computing unit calculates differences between the page interval and image size in a transport direction of the corrected back surface image data. Since these differences indicate shifts of the correction based on the elasticity information, optimal elasticity information can be set by revising the elasticity information with these differences through a setting unit. Consequently, the operator of the apparatus can easily set optimal elasticity information based on the differences.

摘要： An inkjet printing apparatus includes a transport speed detector for detecting transport speed of a printing medium, an inkjet head having a plurality of discharge portions for discharging ink droplets from the discharge portions for printing, and a flushing controller for carrying out discrete flushing from the discharge portions. For an acceleration area of the printing medium where the transport speed detector detects an increase in transport speed before printing, a first discharge rate is set as discharge rate of the ink droplets per unit time for the discharge flushing. For a constant speed area of the printing medium where the transport speed detector detects a substantially constant transport speed during printing, a second discharge rate lower than the first discharge rate is set as discharge rate of the ink droplets per unit time for the discharge flushing.
