Screen printing, also known as stencil printing, is one of the four traditional printing processes. With the advantages of a wide range of substrates, thick ink layers and strong three-dimensional effect, it occupies an important position in the printing industry. Its core principle is to use a screen as the printing plate, form hollow areas of images and texts on the screen through photosensitive plate-making technology. During printing, under the extrusion of the scraper, the ink leaks through the hollow images and texts onto the surface of the substrate, and finally forms a clear printed pattern.
The key to this process lies in screen selection and plate-making accuracy. Screen materials include nylon, polyester, etc. Different mesh counts can be selected according to the characteristics of the substrate. The higher the mesh count, the finer the printed pattern. During plate-making, it is necessary to accurately control the photosensitive exposure time to ensure clear edges of images and texts without burrs, while taking into account the fluidity of the ink to avoid problems such as ink leakage and blurring. The significant advantage of screen printing is that the ink layer is thick and full, the color is rich and bright, and it can achieve special texture effects, making the printed matter highly three-dimensional.
The biggest feature of screen printing is its strong adaptability. It can print on various materials such as paper, cloth, metal, glass, plastic, etc. It is flexible in operation and can be used for both small-batch customization and mass production. Its application scenarios are very wide, covering outdoor advertising, T-shirt printing, glassware, electronic product casings, partial decoration of packaging gift boxes, etc. It is a multi-functional printing process that combines practicality and decorativeness, meeting the personalized printing needs of different industries.
