[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate mounting, inking, embossing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate and mounted on the printing press. Then, the ink is applied to the places with text and images on the printing plate by humans or the printing press, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby replicating printed products identical to the printing plate. The invention and development of the printing press plays an important role in the spread of human civilization and culture. The printing rack of the printing press is a device used to support the printing material and adjust its position to ensure correct printing.
