As one of China's four major inventions, printing has developed into an indispensable technology. The ease and breadth of culture and knowledge dissemination depends primarily on the printing industry. As people's demands and requirements for books become higher and higher, the process of printing technology becomes more complex and efficient. As a part of the traditional printing process, the printing machine directly affects the printing effect and quality. The printing machine control system plays an important role in the normal operation of the printing machine. At present, the printing machine has become a must-have for high-end color printing. This article will introduce you to the silk screen printing machine.
The working principle of the printing machine: the film and PS version are closely attached, and then exposed to ultraviolet light. There are two main reasons for the quality of the sounding version: vacuum, the closeness of the film and the PS version. The source of light, the wavelength of the ultraviolet light is within a certain range, as much as possible "pure". The closeness of the original (such as film) and PS version fit.
The printing machine occupies an extremely important position in the prepress equipment, and its performance directly affects the quality of the plate making, and its maintenance plays a decisive role in the printing production process. If the correct selection, proper maintenance and timely maintenance of the required printing machine can not only improve the service life of the printing machine, but also improve the quality of the printing plate. The temperature rise of the working glass surface of the plate printing machine should be no more than 20 °C. Detection method: the exposure light source is placed in the normal working position, and the surface temperature of the working glass is measured by a point thermometer having a division value of not less than 0.5 °C.
Compared with the LED digital tube, the printing machine has great advantages, and can freely edit the true color picture, which can achieve animation effects. The PLC-based control system is more advanced and more user-friendly than the older models in terms of interface friendliness and functionality.
