The influence of screen spacing on printing quality is mainly reflected in three aspects: pattern clarity, registration accuracy and ink transfer effect. It needs to be dynamically adjusted according to tension, substrate characteristics, etc. (usually 2-3mm).

Screen printing belongs to orifice printing. A simple understanding is to use screen glue to seal the excess mesh area, leave the required image or text, and use a certain pressure to transfer the ink to the substrate through the holes of the stencil to form an image. or text.Screen printing carriers can choose clothing, paper, special paper, conventional metal, plastic products, and many other substrates.

What are the main differences between screen printing and other printing methods?① Strong printing adaptability. The three major printing methods of flat printing, embossing printing and gravure printing can generally only print on flat substrates.Screen printing can not only print on flat surfaces, but also on curved, spherical and concave-convex surfaces.On the other hand, screen printing can be printed not only on hard objects but also on soft objects without being limited by the texture of the substrate.In addition, in addition to direct printing, screen printing can also be printed using indirect printing methods as needed, that is, screen printing is first printed on a 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.②The ink layer is thick, three-dimensional and rich in texture. The thickness of the ink layer for offset printing and embossed printing is generally 5 microns. The thickness of the ink layer for gravure printing is about 12 microns. The thickness of the ink layer for flexographic printing (aniline) is 10 microns. The thickness of the ink layer for screen printing is much higher. exceeds the above ink

Regarding 'green printing', based on the policies we have learned about in the past, the documents we have studied, the meetings we have attended, and the discussions we have participated in, we have tried to analyze it from the concept and background, regulatory standards and evaluation, policy support and guidance, application and practice, suggestions and The five aspects of the measures are comprehensively interpreted for reference by industry insiders.
