Wage principle of screen printing
Screen printing consists of five elements, namely screen printing plate, scraper, ink, printing table and substrate. The basic principle of screen printing is to use the basic principle that the mesh of graphic part of screen printing plate is permeable to ink and the mesh of non-graphic part is not permeable to ink. When printing, the ink is poured into one end of the screen printing plate, and the ink part of the screen printing plate is pressed with a scraper, while moving to the other end of the screen printing plate. During the movement, the scraper squeezes the ink from the grid of the graphic part onto the substrate. Because of the viscosity of ink, the imprint is fixed in a certain range. In the printing process, the scraper always contacts the screen printing plate and the substrate line, and the contact line moves with the movement of the scraper. Because there is a certain gap between the screen printing plate and the substrate, the screen printing plate generates a reaction force on the scraper through its own tension, which is called resilience. Due to the resilience, the screen printing plate is only in movable line contact with the substrate, while other parts of the screen printing plate are not in contact with the substrate. Make the ink and screen break, ensure the printing size accuracy and avoid rubbing the substrate. When scraping the whole layout and lifting the scraper, the screen printing plate is also lifted, and the ink is gently scraped back to its original position. This is a printed stroke.
Commercial advantages of screen printing
* * *1* * general printing is not limited by the size and shape of the substrate, and can only be carried out on a plane, while screen printing can be carried out not only on a plane, but also on a spherical surface and other special-shaped objects, and anything with a shape can be screen printed.
***2*** The layout is soft and the small screen is soft and elastic.
***3*** The ink layer has strong coverage, and it can print pure white on all-black paper, with strong stereoscopic effect.
***4*** is suitable for all kinds of inks.
***5*** Strong optical rotation, which can keep the gloss of printed matter unchanged. * * * Temperature and sunshine have no influence * * *. This makes it possible to print some self-adhesive without additional lamination and other processes.
***6*** Flexible printing method.
* * * 7 * * plate making is convenient, cheap and easy to master.
***8*** Strong adhesion
***9*** can be printed by hand screen or machine.
