Abstract

The invention discloses a method for preparing a screen-printed ultraviolet-induced color-changing earphone wire, which is characterized in that it comprises the following steps: (1) preparing a headphone wire body; (2) preparing an ultraviolet-ray-induced color-changing ink; (3) setting a wire screen printing machine , and select a 100-150-mesh screen printing plate; (4) place the prepared earphone wire body in the wire screen printing machine, then coat the screen printing plate with a temperature-sensitive color-changing ink, and heat it at 45-55° C. Under the temperature conditions, screen printing is carried out according to the preset pattern; (5) Take the headphone cable body with the pattern on the screen printing out of the screen printing machine, put it in a baking oven, and bake it at a temperature of 70-80°C After 0.5-1h, a silk-screen UV-induced color-changing headphone cable is obtained. The invention discloses a product prepared by the method and an anti-counterfeiting application.
