AI Technical Summary
UV printing inks are prone to fading, ink loss, and scratches during packaging box transportation due to friction, affecting the appearance life and shelf appeal of the packaging box.
The colorfast packaging box design using UV printing technology uses a transparent protective plate and fixing block on the printing plate. By using a limiting frame, sliding sleeve, spring, and winding reel, the transparent protective plate is fixed in place, preventing it from slipping out during transportation and protecting the ink.
It effectively prevents UV printing ink from fading, fading, and scratching, thus improving the appearance life of the packaging box and its shelf display effect.
