Screen printing with metal etching

Screen printing requires the production of standard patterned screen printing screens according to printing needs. In the process of pattern decoration, screen printing mainly plays a protective role. When applying photosensitive adhesive, it is necessary to apply more times in order to produce thicker screen templates, which can improve the covering performance and etch patterns with high clarity. The adhesive film of the screen plate undergoes a photochemical reaction under the action of light, causing the illuminated part to crosslink into a water-insoluble adhesive film, while the non illuminated part is dissolved by water and exposes the screen space, thereby engraving a leakage pattern that conforms to the black and white positive film pattern on the coated screen plate.
Fix the silk screen with patterns on the screen printing machine, use alkali soluble and acid resistant ink to print the required patterns on the metal plate, and after drying, it can be etched.
