What is the principle of silk screen yarn?Silk screen yarn consists of five elements: screen plate, scraper, ink, printing table and substrate. The basic principle of screen printing is to use the basic principle of screen printing plate that the part of image and text is ink permeable and the part of non image and text is ink impermeable.

When printing, pour ink into one end of the screen printing plate, apply certain pressure on the ink part of the screen printing plate with the scraper, and move towards the other end of the screen printing plate at the same time.

The ink is pressed to the substrate by the scraper from the mesh of the graphic part during the movement. Due to the stickiness of the ink, the imprint is fixed within a certain range. In the printing process, the scraper is always in line contact with the screen printing plate and substrate, and the contact line moves with the scraper movement. Because there is a certain gap between the screen printing plate and substrate, the silk screen printing plate will produce a reaction force on the scraper through its own tension. This reaction force is called back force Elastic force.
