What is the silk screen printing？

Screen printing is to point to use silk screen version as a base, and by the method of photographic pattern, made with graphic screen plate. Silk screen printing by the five elements, screen plate, scraper, printing ink, printing and substrates. Use screen plate picture and text part of the mesh can be through the ink, the graphic part of the mesh can't through the basic principle of printing ink to printing. At one end of the silk screen plate into the ink printing, scrape threatening the silk screen printing ink on the plate parts a certain pressure, at the same time the screen plate moving at a constant speed at the other end, ink scraper in mobile from the graphic part of the mesh extrusion on the substrates.

Silk screen printing by the five elements, namely, screen plate, scraping scraping plate, printing ink, printing machine, and substrates. Silk screen printing basic principle is: use silk screen printing ink plate picture and text part of the mesh, the graphic part of the mesh is not through the basic principle of ink to print. In silk screen printing on the plate at one end into the ink, scrape printing scraper ink on silk screen printing position a certain pressure, moving in silk screen plate at the other end at the same time. Ink scraper in moving from the graphic part of the mesh extrusion on the substrates. Due to the effect of viscosity of the ink fixation within a certain range, and make the mark scraper is always in the process of printing and silk screen printing and printing substrates in line contact, the contact line with scraper and movement, due to silk screen printing plate and keep some space between the substrates, makes the screen plate through own tension when printing and reaction of scraper, the reaction is called elastic back. Due to the effect of elastic, causes the screen plate and substrates are mobile line contact, only the silk screen plate break with substrates for the rest of the state. Fault movement in the ink and mesh, ensure the dimensional accuracy and avoid smearing printing substrates. When raised after the whole layout of scraper, silk screen printing plate also raised, and the light ink scraping back to the initial position. At this point for a printed itinerary.
