I want to know if there's a way to cut substrate from the back without cutting the vinyl. This way I could peel back the substrate from the middle of a decal rather than the edge. Does anyone know if such a tool or machine exists?
this is what I was trying to only make it small and light weight enough to attach to a Big Squeegee so it would always be handy. I'm not ready yet to offer it for sale. The plotter blade holder may be your best bet for now.test depth of blade on scrap first, but I have used a plotter blade holder with the blade only protruding enough to cut through the backer, but not the vinyl
