Now is a fast developing era. This new era has led to the development of new technology. Screen printing technology has gone to the twentieth Century from thousands of years ago. It is also facing the challenges of this era and experiencing such a labor pains. The development of screen printing in recent years has entered a bottleneck period. Screen printing is one of the main printing methods in the orifice printing. A printing plate mesh, printing the printing ink in the ink scraping plate squeeze from the through holes layout louyin thing on their part to.

Basic technology principle of screen printing:

The basic principle of printing ink by using the screen printing plate in part of the net, and the basic principle of the non graphic part of the mesh without ink. When printing, the ink is poured on one end of screen printing plate, and a certain pressure is applied to the ink part of screen printing plate by scraping and printing scraper. Meanwhile, it moves towards the other end of screen printing plate. The ink is moved by the scraper from the mesh hole of the graphic part to the seal in the movement. Due to the viscous effect of the ink blot. In a certain range, always in the process of printing scraper and screen printing plate and a line contact, the contact line with the scraper moves, due to maintain a certain gap between the screen and substrate, so that the screen printing plate through the tension and cause of the scraper the reaction force, so that the ink and screen the fracture movement, ensure the printing precision and avoid rubbing against dirty substrate. When scraper wind up after the whole layout, and silk screen plate also raised, and the ink scraping back to the initial position.

The process flow of screen printing:

Screen printing is by scraping extrusion elastic open after a screen printing stencil printing paste in need of material, which is currently over a battery process. Screen printing process based on screen printing principle, printing ink to the surface of glass, and then adopting the curing measures of ink, the printed patterns are durable and durable. The process is as follows: stretching, sizing, drying, exposure, developing, drying, cutting down flat glass grinding, cleaning, drying, sintering and printing down.
