Hi Guys, greetings from Sydney, Australia. This is my first post. My business has expanded from embroidery to vinyl decals and am now getting requests for larger signage work. My question is about a backlit menu board in a restaurant. The client wants to update the pricing/menu information, he will be providing the new artwork. It seems to be a full colour print, so I will farm the job out (as my roland cutter will not do for this). My question is (and please remember i'm a complete newb to this), how easy is it to install the new graphic in the lightbox. The pic I have provided is not the best quality (apologies). Is it along the lines of unscrewing the face and replacing the graphic? Is it actually an adhesive? I'm guessing it's hard to tell from the pic what type of system this is, but maybe I can get some advice on how to check the lightbox and see what i'm dealing with. Thank you
