Clean vector art is the starting point, not the finish. A screen printer also needs the design reduced to a set number of inks, detail that the mesh can actually hold, and colors that touch without leaving a gap when the screens shift slightly.
That is the preparation we do on top of the redraw. You get artwork you can separate and burn straight away, instead of a file your printer has to fix before the job can start.
If you only need a scalable logo for general use, our standard vector art conversion is the simpler service. If your artwork is already clean vector and you need it split into films, see color separation.
Source quality matters less than you might expect. We rebuild the artwork rather than tracing pixels, so a small JPG, a scan or a photo of a printed shirt is usually enough to work from.
