How Gravure Printing Machines Work

Introduction to gravure printing machine work:
Gravure printing, referred to as gravure printing, is one of the four printing methods. Gravure printing is a direct printing method that directly imprints the ink contained in the gravure pit onto the substrate. The shade level of the printed image is determined by the size and depth of the pit, if the pit is deep. , the ink contained more, the ink layer left on the substrate after embossing is thicker; on the contrary, if the pit is shallow, the amount of ink contained is less, and the ink layer left on the substrate after embossing It is thinner. The printing plate of the gravure printing machine is composed of a pit corresponding to the original image and the surface of the printing plate. During printing, the ink is filled into the pits, the ink on the surface of the printing plate is scraped off with a doctor blade, and 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.

As one of the printing processes, gravure printing has the advantages of thick ink layer, bright color, high saturation, high printing durability, stable printing quality and fast printing speed in the field of printing and packaging and graphic publishing. Occupy an extremely important position. From the application point of view, in foreign countries, gravure printing machine gravure printing is mainly used for magazines, product catalogs and other fine publications, packaging printing and printing of securities such as banknotes and stamps, but also in special fields such as decorative materials; Domestically, gravure printing machine gravure printing is mainly used for flexible packaging printing. With the development of domestic gravure printing technology, it has also been widely used in paper packaging, wood grain decoration, leather materials and pharmaceutical packaging. Of course, gravure printing also has limitations. The main disadvantages of gravure printing gravure printing are: pre-press plate making technology is complicated, the cycle is long, and the plate making cost is high. Due to the use of volatile solvent, the harmful gas content in the workshop is high, which is harmful to workers’ health. Large; gravure printing practitioners require relatively high treatment.
