[0002] Printing equipment is a general term for machinery, equipment and instruments used to produce printed products and complete the printing process. It is generally divided into three categories: plate-making machinery, printing machines and binding machinery. The printing wheel is an important part of the printing equipment. In the printing process, the ink is printed on the surface of the printed product through the printing wheel.
