Backlit Sign Question on Vinyl

[WVB]

My client has refrigerators for wine/spirits etc. The top piece is white lexan that they want blacked out w/ only the words wine-spirts to be lit in a yellow/gold color. I am not sure how this is done. Black cast vinyl w/ letters cut out then translucent vinyl applied inside of that? If so how do you keep the white from showing between the two? Or is it all just printed as one? Feels like two pieces to me.

I would lay the gold/yellow lettering down first (outline it to trap with the black) then over lay the reverse weeded black...or overlay completely with trans yellow gold and then the reverse weeded black so there is no 'bump'
