With the improvement of people's awareness of environmental protection, hollow boards with environmental protection characteristics are widely used in packaging products, billboards, and display rack manufacturing materials. Printing PP Corrugated Plastic Sheets consists of five elements: screen, printing squeegee, ink, printing table, and hollow board. The basic principle of its printing brush is that some holes in the screen of the printing plate allow ink to pass through and leak the printed matter onto the substrate to form a pattern. The rest of the printing plate will be blocked by the mesh, which will not penetrate the ink and form a blank on the substrate blank.

The traditional method of plate making is manual, while the photochemical method of plate making is more common in modern times. In this plate-making method, the screen is used as a support and fixed on the screen frame, and then the front plate is tightly attached to the negative film to be printed. After exposure and development, the part of the printing plate that does not require ink will encounter light to form a cured printing plate film and sealing net, which will not penetrate the ink during the printing and coating process. During the development process, the printing plate part of the ink needs to be punched, and the ink will penetrate to form ink.

The hollow board can use silk printing technology to make very beautiful billboards, displaying pictures and text on the surface. In order to obtain more significant results, hollow lithography manufacturers should also pay attention to the extraction of ink to increase the sensitivity of the photosensitive adhesive layer and increase the resistivity of the printing. Pay attention to the environment and maintenance of the machine during the production process of the hollow board; pay attention to the treatment with a phosphoric acid solution to stabilize the graphic part; pay attention to wiping the glue when printing, which can effectively protect the layout and avoid the uneven thickness of the glue or even incomplete wiping. The printing plate caused partial damage.
