A machine that prints text and images. Modern printing presses generally consist of plate loading, inking, embossing, and paper feeding (including folding) mechanisms. Its working principle is: first make the text and image to be printed into a printing plate, install it on the printing machine, and then manually or the printing machine apply the ink to the place where the text and image are on the printing plate, and then directly or indirectly transfer it. Print on paper or other substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics) to reproduce the same printed matter as the printing plate. The invention and development of the printing press play an important role in the spread of human civilization and culture. Classification screen printers are divided into letterpress, offset, gravure and stencil printing presses according to the form of the printing plate; the mounting plate and the imprinting structure are divided into flat press, round press and round press. The classification of the screen printing machine is divided by the type of printing plate
