Offset printing

Definition

Offset printing is a widely used printing technique that transfers an image from a metal plate to a rubber blanket, and then onto the printing surface, typically paper. This method revolutionized the printing industry due to its ability to produce high-quality images with consistent color reproduction and efficiency in large volume production. It plays a crucial role in the evolution of printing technology, making it easier and more cost-effective to produce books, magazines, and other printed materials.
