The screen is used as the base, and a screen printing plate with a pattern is made through the photosensitive platemaking method. The printed clothing is placed on the printing table, and the ink is transferred to the clothing through the screen printing plate using a scraper to form a pattern. For multi-color printing, a printing plate must be made for each ink color, and each color is applied to a separate layer. During the production process of electrochromic devices, screen printing is required on the transparent conductive layer (ITO) located on the upper layer. At this time, the product needs to be fixed on the jig, and then the jig is placed on the base of the screen printer.

[0003] The base of the screen printer is equipped with a screen plate with several mesh holes, which allow the airflow generated by the vacuum machine in the screen printer to pass through. When performing screen printing, the jig is placed on the base of the screen printer, and the jig needs to be fixed above the base for screen printing to ensure the final screen printing effect.

[0004] In the prior art, the screen printing jig is directly glued to the base with glue. When the jig needs to be taken down, the glue needs to be peeled off first, and then the jig is taken down.
