I'm a graphic designer. I mainly work in Coreldraw.
I can provide you with the printable artwork, in any scale, as vector artwork.
Best option is a PDF, and being vector it can be rescaled with zero resolution loss.
Problem is, you really don't want an entire sheet of different designs.
Its a big waste of decal paper, isn't it?
It might be better to pick a barricade tape design, and get a few horizontal strips (in the length and scale you want)?
If I can suggest, go for the standard lined tape (second one down below) and avoid the lettered (at such small scale).
if I can help, let me know.
