Process introduction
Silk screen printing generally refers to screen printing, which refers to using a silk screen as a plate base and using a photosensitive plate-making method to create a screen printing plate with graphics and text.
Screen printing consists of five major elements, namely the screen printing plate, squeegee, ink, printing table, and substrate. The basic principle of screen printing is to use the principle that the graphic part of the screen printing plate is permeable to ink, and the non-graphic part is impermeable to ink.
Process characteristics
The characteristics of screen printing can be summarized as follows:
1. Screen printing can use many types of ink. Namely: oil-based, water-based, synthetic resin emulsion type, powder, and other types of ink.
2. The layout is soft. The screen printing layout is soft and has a certain degree of elasticity. It is not only suitable for printing on soft items such as paper and cloth, but also suitable for printing on hard items such as glass, ceramics, etc.
3. The printing force of screen printing is small. Since the pressure used during printing is small, it is also suitable for printing on fragile objects.
4. The ink layer is thick and has strong coverage.
5. It is not limited by the surface shape or area size of the substrate. As can be seen from the above, screen printing can not only print on flat surfaces but also on curved or spherical surfaces; it is not only suitable for printing on small objects, but also for printing on larger objects. This printing method has great flexibility and wide applicability.
Application scope
Screen printing has the advantages of large batches, cheap prices, bright colors, a long shelf life, and fast delivery. It is recognized by more and more industries and is widely used.
Circuit boards of household appliances, patterns on textiles, patterns on T-shirts, cultural shirts, and shoes, text on refrigerators, TVs, and washing machine panels, decorations on ceramics, glass, and wall and floor tiles; various commercial advertisements such as electrical appliances, packaging, outdoor, fixed, mobile and other advertising platforms; in the packaging and decoration industry, screen printing of high-end packaging boxes, packaging bottles, cigarette packs, and wine packs, especially super large outer packaging and product appearance decoration – abnormal application of screen printing It is widely used and closely connected with our lives. Its technology is mainly controlled by many printing factories, while small and personalized screen printing technology is rarely taught in China, and the market is extremely broad!
