Main features of gravure printing machine

The gravure printing machine has many characteristics, is widely used, and is suitable for many fields. Next, we will introduce the main features of the gravure printing machine.

Gravure printing products have the advantages of thick ink layer, rich layers, strong three-dimensional effect, and good printing quality. They are mainly used for printing exquisite color pictures, trademarks, decorations, securities and color newspapers.

The main feature of the gravure printing machine is that the graphic part on the printing plate is concave and the blank part is convex, which is exactly the opposite of the layout structure of the relief printing machine. When the machine is printing a single color, the printing plate is first immersed in the ink tank to roll, and the entire surface of the printing plate is covered with ink. Then, the ink layer belonging to the blank part of the surface of the printing plate is scraped off, the convex part forms a blank, and the recessed part is filled with ink. The deeper the recess, the thicker the ink layer. The machine transfers the ink in the recessed part to the printed matter by pressure to obtain the printed matter. When printing multiple colors, the overprinting method or indirect partial ink coating method is adopted, so that the inks of various colors are distributed on the relevant part of the surface of the printing plate as needed. The basic printing principle of printing multiple colors is the same as printing single color. There are two main types of printing plates used in gravure printing machines, one is photogravure, that is, photocopying plate; the other is engraving plate. The engraving of the engraving plate includes manual engraving, mechanical engraving and electronic engraving.
