• Preparation of Screen Printing Plate A screen printing plate is composed of a screen mesh, a frame, and photosensitive emulsion, among other components. First, the screen mesh is tightly stretched over the frame. Then, a photosensitive emulsion is coated onto the screen mesh. Next, a film with images or text (either negative or positive) is placed over the emulsion-coated screen mesh for exposure. During exposure, the photosensitive emulsion in the areas corresponding to the transparent parts of the film undergoes a photochemical reaction and hardens, while the emulsion in the areas corresponding to the image/text parts of the film remains unexposed and soluble. Afterward, through development, the unhardened emulsion is rinsed off, leaving a hollowed-out area on the screen mesh that matches the images or text on the film. This hollowed-out area serves as the channel through which ink will pass.

• Ink Coating and Scraping An appropriate amount of ink is placed on the screen printing plate, above the area corresponding to the image/text parts. At this point, the scraper (squeegee) installed above the screen starts working. Driven by a precision control system, the scraper moves at a set pressure, angle, and speed in a uniform linear motion (or reciprocating motion) along the surface of the screen printing plate. Under the extrusion of the scraper, the ink passes through the hollowed-out image/text areas on the screen printing plate, transfers to, and adheres to the flat substrate below, thereby replicating the same images or text as those on the printing plate.
