Gravure printing machine operation book

At a stage of rapid economic development, the contradiction between economic growth and environmental pollution and cost expansion has intensified, but this contradiction is not impossible to reconcile. In the highly polluting printing industry, green printing is popular. In the process of continuous improvement of many printing equipment, how to make gravure printing machine have advantages in saving cost and reducing pollution? This article will introduce you to the gravure press operating books.

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 on the back of the impression cylinder to eliminate static electricity on the paper. In addition, increasing the humidity in the printing shop is conducive to the elimination of static electricity.

The plate cylinder is the determining factor in determining the amount of ink on the print of the gravure press. The viscosity of printing ink is the most important factor affecting the amount of ink on the printed matter, and it is also an important factor affecting the printing speed. The viscosity of the ink is known from the measurement, and the thickness of the ink is obtained by the perception. The two are closely related. Although the viscosity is not equal to the thick and thin, the viscosity and the thick and thin results are inseparable when actually measured with the paint cup and the Zahn cup.
