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 etched into the metal plate, sometimes with the use of a laser . The metal plate is bathed in ink during the process and then wiped clean before application to the substrate. While gravure printing can produce high-quality results rapidly, the costs are significantly higher than other printing methods, including flexography or various forms of digital printing .
