I guess then that would only leave making a cast of some sort from a positive like your finished sign then? I just ask mostly because it would interesting to know how to possibly achieve the raised effect which was more durable for an outside installation.
In a way it reminds me of those old printing plates I think were made from Linotype that were cast out of lead or tin or something in the old days of newspaper printing. I'm not sure these are the actual plates or raised as much as I remember.
I can't find a shot of exactly what I'm remembering seeing in a printing museum in California, but the new plates were silver that I remember and the type raised pretty much about like they are on yours.
I guess the only way to make a mold would be to have the letters reverse engraved into a plate in some fashion or live with the slight rounding that the smallest CNC bit would leave? If the letters were negatives in a flat plate that would at least leave a cast white field smooth. Which would leave the question what kind of material could one cast that would be durable and translucent? I'm guessing one can't home cast PVC?
