Sorry I should've been clearer - to answer both questions:
I'm building a replica-ish of the European/UK robotron and I didn't have the time/space/tools this time round to do the woodworking myself so I bought a kit that was mighty similar to the robotron shape. The kit comes with the marquee and bezel plexi already cut to size and the grooves already in the wood.
To sandwich I'd have to get a couple of new sheets to the exact dims (667 x 678 mm
) of half thickness and hope it would work with the extra thickness of the bezel vinyl.
So it's not that it won't work but it involves a lot of extra hassle that I could do without - I'd probably rather just stick it on the front of the plexi if that was the only option.
The same may be true of someone who can backprint on plexi but that at least would be easier - albeit still means buying more plexi.
If anyone is aware of any service that does print with the adhesive on the printed side or backprints on plexi I'd love to hear it.
