printing press

a type of printing machine that uses a flat metal plate with a design etched into it to transfer ink to paper

A printing press is a machine used to produce multiple copies of text or images. It works by applying ink to a surface, such as a metal plate or wooden block, which has the text or image raised on it. The inked surface is then pressed against paper or another material, transferring the ink and creating a print. This machine makes it possible to quickly and efficiently produce books, newspapers, and other printed materials in large quantities. The invention of the printing press greatly increased the spread of information and made printed materials more accessible.
