Screen printing meshs, because of the advantages of universal printing, will be applied to screen printing meshs in all walks of life. Therefore, the market supply of screen printing meshs is also growing. Screen printing can be printed not only on hard objects, but also on soft objects, regardless of the texture of the substrate. In addition to this, in addition to direct printing, screen printing can also be printed by indirect printing method as needed, that is, screen printing on gelatin or silicone plate, and then transferred to the substrate. Therefore, it can be said that screen printing is highly adaptable and has a wide range of applications.
The most basic working principle of screen printing mesh:
Screen printing consists of five major components, namely screen plates, squeegees, inks, printing stations, and substrates. The basic principle of screen printing is to use the basic principle of the screen printing plate to penetrate the ink, and the non-image part of the mesh is not transparent.
The ink is poured on one end of the screen printing plate during printing, and a certain pressure is applied to the ink portion on the screen printing plate by the squeegee blade while moving toward the other end of the screen printing plate. The ink is squeezed from the mesh of the graphic portion onto the substrate by the squeegee during movement. Due to the viscous action of the ink, the print 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 due to the screen printing plate and the substrate. A certain gap is maintained between them, so that the screen printing plate at the time of printing generates a reaction force against the squeegee by its own tension, and this reaction force is called a resilience force. Due to the resilience, the screen printing plate and the substrate are only in a moving line contact, and the other portions of the screen printing plate are separated from the substrate. Breaking movement of the ink and the screen ensures print dimensional accuracy and avoids smuddy substrates. When the scraper scrapes across the entire surface, it is lifted, and the screen plate is lifted, and the ink is gently scraped back to the original position. This is a printing trip.
The working principle of screen printing mesh is the above. The printing process is also relatively orderly, and the ink and other aspects also need attention. If you have any questions, please feel free to contact us.
