Vinyl signs are ubiquitous and are fairly easy to design, make and install.
There are a lot of material options: Indoor-rated, Outdoor-rated, Reflective, Colors, etc. USCutter & Signwarehouse are two most populat vendors for sourcing materials. Haystack has a number of common colors in stock (white, black, etc.) but if you wanted a specific color to match the Taconnet brand, you can take a look to see if there is a good match on one of those websites.
Vinyl on glass is a classic application - most store window signage is vinyl. White tends to look really nice, unless you have a specific branded color you wanted to use as an accent color.
The other common application is to apply vinyl to a wall or indoor surface (dry wall, etc.). Contrast is usually important, so black vinyl on a white wall will tend to look nice. That said, lots of colors work well on a white-painted surface.
Vinyl on wood can work, depending on the surface quality of the wood. It is not as common to do this and there are better ways to make wood signage using the other machines in the Fab Lab.
