Excuse me, what kind of material is used for the outermost advertising color pattern of the LED light box, and what kind of printing is it?

Hope this helps!

The colorful pattern outside you are referring to, are you referring to the LOGO or the picture? If you are referring to the picture, then you must use a "translucent light sheet". If you are referring to the LOGO, the one used should be absorbent. Plastic (usually red, yellow, blue, green, white, purple)

The translucent lamps are sprayed out by large-scale inkjet printers.

Blister molding must be pressed out with a mold. The common method is to cut the light-transmitting plastic sheet of the corresponding color and then glue it on.
