What is the principle of silk screen mesh? Xurui Net Industry Xiaobian told you that silk screen printing mesh is composed of five major elements, namely screen printing plate, scratch scraper, ink, printing table and substrate. The basic principle of screen printing mesh is: the basic principle of screen printing plate graphic part mesh transparent ink, non-graphic part mesh impermeable ink printing.

During printing, pour ink on one end of the screen printing plate, apply a certain pressure to the ink part on the screen printing plate with a scratch scraper, and move towards the other end of the screen printing plate at the same time.

The ink is squeezed from the mesh of the graphic part to the substrate by the scraper while moving. Due to the viscosity of the ink and the imprinting is fixed within a certain range, the scraper is always in line contact with the screen printing plate and the substrate during the printing process, the contact line moves with the scraper moving, because the screen printing plate and the substrate maintain a certain gap, so that the screen printing plate during printing through its own tension and produce a reaction force on the scraper, this reaction force is called springback.

Due to the rebound force, the screen printing plate and the substrate are only in contact with a moving line, while the other parts of the screen printing plate are detached from the substrate. The breaking movement between the ink and the screen ensures the dimensional accuracy of the printing and avoids rubbing the dirty substrate. When the scraper is scraped over the entire layout, it lifts the screen plate and gently scrapes the ink back to its original position. This is now a printed itinerary.
