Silk screen drawing: It is because of the increase of ink viscosity that ink thinner needs to be added to reduce the ink viscosity, and everything else remains the same. In addition, the printing speed slows down and the printing pressure becomes lighter.
Screen printing: Screen printing belongs to stencil printing, which is called four printing methods together with lithography, gravure printing and gravure printing. Stencil printing includes copying stencil, engraving stencil, stencil printing and screen printing. The principle of stencil printing is that when printing, the ink is transferred to the substrate (paper, ceramics, etc.). ) pass through the perforation of the template with a certain pressure to form an image or text.
Working principle:
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.
