In the electrical aspect of the automatic flat screen printing machine, we use computers and programmable controllers as the core. The industrial computer is the upper computer, which uses computer communication to collect and exchange data with the single-chip computer system of the printing unit and monitor the whole machine. In terms of software, graphical computer monitoring software is developed on the basis of windows, with beautiful interface and intuitive and easy-to-understand Chinese display. In order to improve the reliability of the printing unit.
The ink will not block the screen, and the density is stable, suitable for high-quality printing. Solvents are an important part of screen printing inks. Different regions have different temperature and humidity, and the performance of the ink is also different. Some people say that 90% of the problems in the screen printing process are related to solvents. UV ink does not contain volatile substances, the ink viscosity changes little, and it is easy to operate. It solves these problems and greatly improves the printing quality. In addition, due to the fast curing speed of the ink, the residence time of the printed matter during the drying process is shortened, and the possibility of contamination by dust is reduced.
does not contain volatile solvents and has no negative impact on the human body and the environment. At present, in terms of output and variety of screen printing inks, volatile and drying solvent inks are the mainstream. Because of its slow drying time, 60% of the solvent must be volatilized during the drying process, which pollutes the environment. Seeking inks with less pollution, fast drying, and less energy consumption has become the common goal of the printing industry.
