Gravure Printing
Gravure is a printing method in which an image is applied to a printing substrate by use of a metal plate mounted on a cylinder. Unlike other processes, gravure uses a depressed or sunken surface for the desired image. The image to be reproduced is engraved into the metal plate, sometimes with the use of a laser or electronically all the image are screened, creating thousands of tiny cells on the metal plate. These tiny cells carry the ink from the tray while the excess of ink is stripped off by the means of a blade. The impression roller is presses the web (roll of plastic or paper) against the form cylinder and the ink penetrates into the web creating the printed image by capillary action which draws the ink upward against the force of gravity to enters the web. The printed web is then dried in ovens between one printing unit and the next by high velocity heated air. After the last color has been applied and dried, the web is wound back into the original roll form. Gravure printing presses configuration is particularly flexible; these machines are best suitable for the production of all kinds of packaging materials with various formats. These prints can be found on cans food, boxes, and bottles such as Coca-Cola, Pepsi, Fanta and many more.
