Gravure printing, referred to as gravure printing, is one of four printing methods. Gravure printing is a direct printing method. It directly prints the ink in the pits on the substrate. The depth of the printed image is determined by the size and depth of the pits. The deeper the pit, the more ink, and the thicker the layer of ink left on the substrate after embossing. Conversely, if the pits are shallower and the ink volume is lower, the ink layer left on the printed substrate is thinner. Gravure is made up of pits and the surface of the printing plate corresponding to the text of the original. When printing, the ink is poured into the pit, and the ink on the surface of the printing plate is scraped off with a scraper. There is a certain pressure contact between the printing plate and the substrate, and the ink in the pit is transferred to the substrate to complete the printing. Gravure printing, as a kind of printing process, occupies an extremely important position in the fields of printing and packaging and graphic publishing due to its advantages of thick ink layer, bright color, high saturation, large printing plate resistance, stable printing quality and fast printing speed. . From the application point of view, in foreign countries, gravure printing is mainly used for high-quality publications such as magazines and product catalogues, packaging printing and printing of securities such as bills and stamps, and also used in special fields such as decorative materials; in China, gravure printing is mainly used for For flexible packaging printing, with the development of domestic gravure printing technology, it is also widely used in paper packaging, wood grain decoration, leather materials, pharmaceutical packaging, food packaging, daily chemical packaging, etc. Of course, gravure printing also has limitations. Its main disadvantages are: the pre-press plate-making process is complex, the cycle is long, and the cost is high;
Chengyi packaging and printing equipment commonly uses 9-color gravure printing machine, which can print 9 different colors at the same time, very fast, and the printed products have clear and full colors.
