Very interesting stuff. I have spent quite a bit of time creating a vector trace of my Klondike backglass. The reason for the vector drawing is to make the use of spot colors possible. Even though the inkjet printer I will use is cmyk, it has a set of spot color swatches that it does a great job with. My intention is to print the artwork on translucent vinyl with the windows cut out. Then create a second layer on opaque vinyl of just the lighted shapes cut out. Line up both and laminate them together and mount them behind glass like a translite.
