The printing speed of the gravure printing machine is first determined by the length of the transfer distance between the colors of the printing press. Because of the color on the printed product when printing, if the ink of the previous color is not dried, the ink of the latter color will dissolve the pre-colored ink, causing coloring. Therefore, the longer the transfer distance between the inks of the gravure printing machine, the longer the natural drying time, the higher the printing speed can be, and the more difficult it is to increase the printing speed. This article will introduce you to high speed computer gravure printing presses. The gravure press blade should be placed at an appropriate height. The blade should be adjusted according to the printing speed. The printing speed is fast, the distance from the embossing point is far, the printing speed is slow, and the embossing point is closer. The tension control of the unwinding tension zone of the gravure printing press is mainly performed by the uncoiler. Tension control is a main function of the uncoiler, so the control principle of the tension zone is consistent with the working principle of the uncoiler. The clutch, tension roller and tension controller form a closed-loop control system. During the printing process, the paper is not easy to be separated, the paper on the delivery table is not properly received, or the paper on the paper feeding table is skewed and the overprinting is not allowed, etc., which may be caused by static electricity. To eliminate printing static electricity, a static eliminator is generally installed on the printing machine to ionize the air around the printing machine, thereby neutralizing the positive and negative static electricity on the paper. It is also possible to spray an appropriate amount of water mist around the gravure printing machine or behind the impression cylinder to remove static electricity from the paper. In addition, increasing the humidity in the printing shop is conducive to the elimination of static electricity. In response to the current international and domestic technology, Zhongshan Youwei Printing Equipment Co., Ltd. has invested a lot of manpower and financial resources in 2006. At present, UV gravure printing machines under solvent-free N2 protection conditions have been successfully developed, and a number of national invention patents have also been obtained. The UV gravure press with N2 protection is the world's leading target for zero emission of organic volatiles (VOC) in gravure printing. At the same time, the application of UV ink on gravure printing machine is also solved, and the printing quality of gravure printing is greatly improved by UV ink printing.
