Flat Screen Printer printing is composed of five major elements, namely screen printing plate, scraper, ink, printing station and substrate. The basic principle of a flat screen printing machine is to use the basic principle that the screen part of the screen printing part is permeable to ink, and the non-graphic part is not permeable to ink. During printing, pour ink on one end of the screen printing plate, apply a certain pressure on the ink portion of the screen printing plate with a scraper, and move toward the other end of the screen printing plate at the same time. The ink is squeezed by the scraper from the mesh in the graphic part to the substrate while moving. 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 plate and the substrate. The contact line moves with the movement of the squeegee. Because the screen plate and the substrate Maintain a certain gap between them, so that the screen printing plate during printing generates a reaction force against the scraper through its own tension. This reaction force is called the rebound force. Due to the resilience, the screen printing plate and the substrate are only in mobile line contact, while the other parts of the screen printing plate are in a detached state from the substrate. The ink and the screen are broken, which guarantees the dimensional accuracy of the printing and avoids smearing the substrate. When the squeegee is scraped across the entire surface, it is lifted, and the screen printing plate is also lifted, and the ink is gently scraped back to the original position. This is a printing trip.
