Letterpress printing plates, also known as relief printing plates, are used in the letterpress printing process, which involves pressing ink onto paper using a raised surface. Additional synonyms for letterpress printing plates include relief plates, printing blocks, stereotype plates, or cliches. Relief plates have a positive image, and the printing surface is raised above the background. Printing blocks are typically made from wood or metal, and they are carved with the intended design to be transferred onto paper. Stereotype plates are usually made by casting a duplicate of the original plate, while cliches are created by transferring an image to a metal plate. Regardless of the term used, letterpress printing plates are essential tools for creating high-quality printed materials.
