Printing machinery

The main feature of gravure printing machine is that the graphic part on the printing plate is concave and the blank part is convex, which is just opposite to the layout structure of gravure printing machine. When printing monochrome, the machine first rolls the printing plate in the ink tank, and the whole printing plate surface is coated with ink layer. Then, the ink layer belonging to the blank part on the surface of the printing plate is scraped off, and the convex part forms a blank, while the concave part is filled with ink. The deeper the concave part is, the thicker the ink layer is. The machine transfers the ink in the concave part to the printed matter through pressure, so as to obtain the printed matter.

When printing multi-color, overprint method or indirect local inking method is adopted, so that the inks of various colors are distributed on the relevant parts of the printing plate surface according to the needs. The basic printing principle of printing multi-color is the same as that of printing single color. There are mainly two kinds of printing plates used in gravure printing press. One is photographic gravure, that is, photocopying plate; The other is engraving. The engraving of engraving plate includes manual engraving, mechanical engraving and electronic engraving.
