Rotogravure printing is a high-speed printing process that uses a cylinder engraved with images or text. The cylinder is coated with ink, and the excess is wiped off, leaving ink only in the engraved areas. This method is commonly used for printing magazines, packaging, and wallpaper due to its ability to produce high-quality images and vibrant colors. The process involves transferring the ink from the cylinder to the substrate, such as paper or plastic. Rotogravure is known for its efficiency in long print runs, making it cost-effective for large-scale production. It also allows for continuous printing, which is ideal for various commercial applications.
