screen printing machine how it works?

Screen printing presses can print almost everything you see right now, and it's called a universal press. It is through the screen to the screen printing ink in accordance with the shape of the screen to leak to the printed surface of a device. so, screen printing machine how it works?

Screen printing is the silk fabric, synthetic fabric or metal mesh stretched in the frame, the use of hand-carved paint film or photochemical plate making screen printing plate. Modern screen printing technology, it is the use of photographic materials through the photolithography method of making screen printing plate (screen printing plate on the graphic part of the screen hole for the through hole, rather than the graphic part of the screen is blocked live). Printing squeegee squeegee, the ink through the graphic part of the mesh transferred to the substrate, forming the same as the original graphic.

screen printing machine how it works？

Screen printing machine printing basic working principle is: the use of screen printing plate graphic part of the network through the ink, non-graphic part of the mesh impermeable ink for printing. Printing ink into the screen at one end, with a squeegee scraper in the screen printing ink on the site to exert a certain pressure, while moving toward the other end of the screen printing plate. The ink is squeezed by the squeegee from the mesh of the graphic part onto the substrate during the movement. Due to the viscous effect of the ink, the imprinting is fixed within a certain range. During the screen printing process, the squeegee always comes in line contact with the screen printing plate and the substrate, and the contact line moves with the squeegee. Since the screen plate and Keep a certain gap between the substrates, making the screen printing plate through its own tension generated scraper reaction force, this reaction known as the resilience. As a result of the role of resilience, the screen printing plate and the substrate was only moving line contact, and other parts of the screen plate with the substrate from the state. The ink and screen rupture movement to ensure the printing size accuracy and to avoid rub dirty substrates. When the scraper scrape the entire layout after the lift, while the screen printing plate is also raised, and the ink scraped back to the initial position. This is a printing trip.

Screen printing machine printing is the main screen printing machine, screen printing network and scraping board. Screen printing machine printing in a large number of printing process is relatively simple, but also the most widely used. Understand screen printing machine how it works, and it's easier and more efficient when you're using it.
