A press plate is a flat, rigid surface used in various printing processes, such as lithography and screen printing. It serves as a medium to transfer ink onto paper or other materials, creating images or text. The design is often etched or engraved onto the plate, allowing for precise reproduction of artwork. In addition to printing, press plates are also utilized in metalworking and manufacturing to shape or form materials. They can be made from various materials, including metal and plastic, depending on the specific application and desired durability.
