Offset printing is a method of printing in which ink is transferred from a plate to a rubber blanket and then to the printing surface. This method is commonly used for printing large quantities of high-quality documents such as books, magazines and newspapers. The process involves creating a printing plate, which is a metal or plastic surface with the image to be printed etched or engraved into it. Ink is then applied to the plate and transferred to a rubber blanket, which in turn transfers the ink to the paper or other printing surface. Offset printing offers high accuracy, consistency and quality and is widely used in commercial printing.
