Gravure printing, referred to as gravure printing, is one of the four major printing methods. Gravure printing is a direct printing method, it will be the ink contained in the pit of the intaglio plate directly embossed on the substrate, the thickness of the printed image level is determined by the size and depth of the pit, if the pit is deeper, it contains more ink, embossed on the substrate left on the thicker layer of ink; on the contrary, if the pit is shallow, it contains less ink, embossed on the substrate left on the thinner layer of ink. Gravure printing plate is composed of a crater corresponding to the original text and the surface of the printing plate. When printing, the ink is filled into the pit, the ink on the surface of the plate is scraped off with a squeegee, and there is a certain pressure contact between the plate and the substrate to transfer the ink in the pit to the substrate to complete the printing. (Printing machine, gravure printing machine, color printing machine) The invention and development of the printing machine has played an important role in the spread of human civilization and culture.
