[0002] A gravure printing press is a machine that uses a gravure plate for printing. The image and text part of the printing plate is concave, while the blank part is on the same plane as the outer circle of the plate cylinder. When the gravure printing press is printing, the entire surface of the plate cylinder is inked, and the ink on the blank part of the plate is scraped off with a scraper, leaving the ink on the image and text part. The paper is then passed, and the impression cylinder is used to imprint on the back of the paper, so that the ink in the concave part is directly transferred to the paper surface. Finally, the printed matter is stacked or rewound through the paper collection part.
