The gravure printing of gravure presses, referred to as gravure printing, is one of the four printing methods. Gravure printing is a direct printing method, it will directly imprint ink contained in the gravure pits to the substrate, the printed picture level bias is determined by the size and depth of the pit, if the pits is deep, the ink containing more ink layer, leaving imprinted substrate is thick;
On the contrary, if the pit is shallow, then the amount of ink contains less, after printing, the ink left on the substrate is thinner. An intaglio printing plate is composed of a concave surface corresponding to the original text and the surface of the printing plate. When printing, the ink is filled into the pit, and the ink on the surface of the printing plate is scraped with an scraping knife, and there is a certain pressure contact between the plate and the substrate, and the ink in the pit is transferred to the substrate to complete the printing.
This is the definition of gravure printing of gravure presses.
