Running theory of screen printing machine



There is a layer of photosensitive adhensive with high concentration nitrogen on the top of screen mesh plate, which has an exposure reaction with film closely, the part that is not photosensitive will shed from the shadow at this time, then it presents screen mesh which can make ink pass through. Screen mesh plate will be coated a layer of Ink normally before printing running. Then a scraper will automatically be scraping screen mesh plate to extrude ink. Finally the Ink will be transfered to the surface of the materials. That means you can make different beautiful paintings on the surface of many kind of materials, such as Clothing label/narrow fabric/elastic tapes,luggage webbings,lashing straps/heavy duty webbings,woven label,satin ribbon,lanyard etc.
