Light Boxes

[artray]

Checking to see if lightboxes are used for overlaying graphics on top of each other.
Last year I had one built out of spare parts and it worked really great in getting vinyl graphics overlayed perfectly. I sold it a few months ago due to relocating to the USA.
Is this something used by the 'pros' and if so where can I purchase one?

Not used much anymore thanks to digital printing.
We always used an old sign box or made one.
