Gravure printing has the characteristics of high printing durability, large thickness of printed ink layer, high printing color, etc. It is widely used in the printing of high-grade printed matter such as paper and film. The graphic portion of the gravure printing plate is recessed by etching, engraving or the like to form a cell; the blank portion is on the same cylinder as the outer circle of the plate cylinder. At the time of printing, the plate cylinder is immersed in the ink tank or ink is supplied through the transfer roller to achieve full-face ink application. During the rotation of the plate roll, the squeegee scrapes off the ink in the blank portion of the plate, leaving the ink in the image portion.
