Printing plates at the end of the wire into ink used in the screen scraping scraper printed on the printing plate to exert a certain pressure parts ink, silk screen printing plate at the same time North Korea the other side of Mobile. Ink was in the mobile scraper from the graphic part of the mesh in the extrusion to the substrates. Because of the role of viscous ink blot fixation within a certain range, the printing process has always been with the screen scraper plate and substrates linear contact, contact with the scraper moving line of mobile, as the screen printing plate and substrates maintain a certain gap between, making the screen printing plate through its own tension arising from the reaction of the scraper, the reaction known as the back stretch. Because of the role of resilience, so that screen printing plate and printing materials are mobile lines were exposed, and screen printing plate and other parts of substrates for out of state. To  make ink and screen broke campaign to ensure that the printing dimensional accuracy and to avoid rubbing dirty substrates.
