[0002] With the rapid development of the printing industry, printing equipment is a machine for printing text and images, and has become an indispensable tool in modern printing processing. Modern printing presses are generally composed of plate mounting, inking, embossing, and conveying mechanisms. The working principle of printing equipment is: first, the text and image to be printed are made into a printing plate, which is mounted on the printing press, and then the printing press applies ink to the place where the text and image are on the printing plate, and then directly or indirectly transfers it to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby replicating the same printed products as the printing plate. Modern printing equipment is developing towards remote automation, linkage, and serialization.
