[0002] Screen printing refers to the use of a silk screen as a base, and through the photosensitive platemaking method, to make a silk screen printing plate with images and texts. The silk screen printing plate, scraper, ink, printing table and substrate are used for printing based on the basic principle that the mesh holes of the graphic part of the silk screen printing plate can pass the ink, while the mesh holes of the non-graphic part cannot pass the ink.
[0003] When screen printing is used to print products, the screen needs to be aligned with the substrate on the workbench so that the graphic template on the screen is aligned with the substrate. Then the control panel is operated to make the printing press run. At this time, the control frame will drive the scraper to move and make the screen contact with the substrate, so as to carry out the corresponding printing process. However, it is found in actual use that the assembly frame for installing the screen has a larger space on the inner wall in order to have a space margin for adjusting the horizontal left and right position of the screen. At this time, when adjusting the left and right spatial position, the screen is prone to position deflection, resulting in deviation in the alignment of the graphic template on the screen with the substrate, affecting the processing effect of the printing press and the finished product effect of the substrate.
