How to make multi-layer color blister light-emitting letters

I am a professional to do luminous characters such as: plastic absorbing characters, plastic absorbing light box, LED exposed characters, through body characters, infinity characters, aluminum characters and so on.

You said multi-layer color blister characters should be double or triple blister characters.

The practice of double-layer plastic word: first suck a layer of base plate, and then suck a layer of the word above, and then use kraft paper to write a good draft of the word above the layer of the word, the upper layer of the word is fixed on the bottom layer, with plexiglass glue. Then make a hole in the back of the bottom layer, and then hollowed out with a small gazetteer, so that the light can penetrate. Three layers of the same practice.

There is also a flat multi-layer color blister, the practice is: suck a layer of white panels, and then paste transparent film.
