Gravure Printing Is A Kind Of Engraving Gravure

Gravure printing is a kind of engraving gravure,which was first invented in Italy in 1452.Gravure printing is a direct printing method,which directly imprints the ink contained in the gravure pit onto the substrate.The thickness of the printed image is determined by the  size and depth of the pit.If the pit is deep,there is more ink,and the ink layer left on the substrate after the imprinting is shallow.The ink content is less,and the embossing is thinner.The printing plate of intaglio printing is composed of pits corresponding to the original drawing civilization and the surface of the printing plate.During printing,the ink is filled into the pit,and the ink on the printing plate surface is svraped off with a doctor blade.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 printing.All the plastic bags you see in the supermarket are printed on the inside of the film,not on the outside.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 drug packaging
