タイトルまたは説明

Modern printing presses are generally composed of mechanisms such as plate loading, inking, embossing, and paper delivery (including folding). The working principle is: first to be printed text and images made of printing plates, mounted on the printing machine, and then by hand or printing machine ink coated on the plate with text and images, and then directly or indirectly transferred to the paper or other substrates (such as textiles, metal plates, plastic, leather, wood, glass and ceramics), so as to reproduce the same printed materials with the plate. (Printing machine, gravure printing machine, color printing machine) The invention and development of the printing machine has played an important role in the spread of human civilization and culture.
