1: Screen printing, also called silk screen printing,serigraphy,silk printing,or organic stoving
Refers to the use of silk screen as a plate base, and a screen printing plate with graphics and text is made by a photosensitive plate-making method. Screen printing consists of five elements, screen printing plate, squeegee, ink, printing table and substrate.
The basic principle of screen printing is to use the basic principle that the mesh of the graphic part of the screen printing plate is transparent to the ink, and the mesh of the non-graphic part is not permeable to the ink.

2: Processing
When printing, pour ink on one end of the screen printing plate, apply a certain pressure to the ink part of the screen printing plate with a scraper, and move to the other end of the screen printing plate at the same time. The ink is squeezed onto the substrate by the scraper from the mesh of the graphic part during the movement. Due to the viscosity of the ink, the imprint is fixed within a certain range. During the printing process, the squeegee is always in line contact with the screen printing plate and the substrate, and the contact line moves with the movement of the squeegee. A certain gap is maintained between them, so that the screen printing plate during printing generates a reaction force on the squeegee through its own tension. This reaction force is called rebound force. Due to the effect of the resilience, the screen printing plate and the substrate are only in moving line contact, while the other parts of the screen printing plate and the substrate are separated. The ink and the screen are broken, which ensures the printing dimensional accuracy and avoids the smearing of the substrate. When the scraper scrapes the entire layout and lifts up, the screen printing plate is also lifted, and the ink is gently scraped back to the original position. So far it's one printing procedure.
