Offset printing dual sided on paper/foil for posters used in light boxes has been a common practice for years. Bus stops in The Netherlands at a size of 168x118 cm for example. More sophisticated is a slight blur for the mirrored print at the back and its color adapted to the fluorescent tubes used.

I agree with that idea for a possible approach, may I please ask, have you tried it and had success?
Yes, I’ve been doing it that way for many years with perfect success.
I imagine there may be a little compensation of brightness needed (as with printing images to go in frames under glass) as the glass inevitable absorbs some luminance.
Exactly. I hate making manual curves but this is a perfect example where it makes sense. If the RIP you’re using let’s you do it, I’d recommend it.
I guess there is also a possibility of the inks behaving differently when going down onto white paint rather than straight onto glass.
No, not really - not with UV Curable.
Years ago, one of my clients claimed to invent ‘oreo’ printing where he would print UV colors on plexi, then white and then the colors again. This would make not only a double-sided reflective print but also a transmissive print with incredible DMax and saturation. He carved a nice niche and has done a whole bunch of special installations around the US with this, working closely with the designers and with me tweaking the calibration for different kinds of situations. These are the fun jobs, where people are thinking outside the box, care about making a high quality product and enthusiastically want to involve the color guy.
