Gravure printing Process is a form of intaglio printing. The technique uses a depressed or sunken surface for formation of the image. The image area consists of honey comb shaped cells that are etched or engraved into a copper cylinder. The unetched area of the cylinder represents the non-image or unprinted areas. The cylinder generally rotates in a bath of ink called the ink pan. With the turning of cylinder, extra ink gets wiped off the cylinder due to a steel doctor blade. Image is formed due to the direct transfer of the ink to the substrate ( paper or any other material) while it passes between the plate cylinder and the impression cylinder.
