How to UV Reverse Print on Thin Plexi, Self Adhesive?

[xmarksthespot]

I've seen companies like Jersey Jack Pinball advertise what they call RADCAL which looks like reverse UV printing on thin acrylic / plexi. Barrels of Fun pinball has a version of this as well, they said they have two suppliers for it.

I understand the reverse UV portion of this process, the thing I don't understand is how they're then making it self adhesive. Is it a laser cut double-sided tape of some kind? Curious if anyone here has experience with this. Thanks!

Probably applying mounting film, basically a laminate with adhesive and liner on both sides

IN THE DISTANT PAST DAIGE MADE SYSTEMS to apply a layer of clear adhesive & a release liner

i would imagine they use modern technology along the same lines

The owner of Barrels of Fun talks about it around the 30:30 mark in this video. He mentions a 3mil 3M adhesive, so that's perhaps the mounting film? He also says they apply mirroring - curious if anyone has any insight on that as well! My UV printer has an adhesive channel for applying leaf, I wonder if that's the same process?

They're just applying mounting adhesive to the back after they print it. There's a ton of different brands and products you can get. We use 3M 467 for a lot of things, just depends what you're doing. I thought at first he was saying that he mirrors the graphic to print subsurface, but it seems like they have applied something that looks like a mirror or chrome, not sure what that is, Maybe just chrome film of some sort to make the image pop?
