Common types include offset printing presses, letterpress printing presses, gravure printing presses, flatbed printing presses, etc. Printing presses can print various texts, patterns, images and other information, and are widely used in manufacturing, printing, packaging and other fields. The main uses of printing presses include: producing advertising and packaging materials, manufacturing cultural supplies, manufacturing commercial printed materials, manufacturing various papers, cards, etc., all of which use the interaction between the printing plate and the printing material to transfer information such as patterns and texts to the printing material. In the printing process, it is usually necessary to coat the raised part of the printing plate with ink or other printing materials, and then transfer the ink or printing material to the printing material through the pressure of the scraper or the printing material to complete the printing of the required information.
