Rotogravure printing is to fill the entire surface of the printing plate with ink, and then use a special scraping mechanism to remove the ink in the blank part, so that the ink only remains in the cells of the graphic part; and then under greater pressure , Transfer the ink to the surface of the substrate to obtain printed matter. Gravure printing belongs to direct printing.
The rotogravure printing machine is usually composed of eight parts, including the unwinding part, guide roller, pressure roller, printing roller, inking part, doctor blade, dryer, and winding part. Some gravure printing machines also include power system, calibration system and electrical system.
Intaglio printing, because of the high degree of automation of the printing machine and good plate-making quality, the process operation is simpler and easier to master than lithographic printing. The process flow is as follows: Pre-press preparation→Pre-printing→Adjusting the rules→Formal printing→Post-press processing.
Gravure printing uses a large amount of ink, the graphics and texts are convex, and the layers are rich, the lines are clear, and the quality is high. Most of the printing of books, magazines, magazines, packaging and decoration is gravure printing.
General soft materials can be used as substrates for rotogravure printing presses. Such as plastic, paper, aluminum foil, etc.; especially for some materials that are easy to stretch and deform, such as textile materials.
