Very interesting idea!  Just one question.. what would you do about any light up lettering on ther rear side of the glass using this technique.. ie that is normally accomplished when the silver mask is screened onto the original glass??

My guess is you would need to scan/photograph the rear side of the glass as well so that an overlay/decal could be printed and stuck over the rear side of the glass after the main art has been applied. Just my thoughts..

Cant wait to see how this turns out!!

cheers... Mitch
