New user here! A couple of quick questions. Attached are photos of a heat pressable number transfer for a polyester jersey. What type of printing and printer would create this as best as possible? Also it appears that there are 3 layers here if I'm not mistaken with a transfer sheet, ink and some type of black adhesive. What is this sandpaper like adhesive and how is it applied to this transfer? Thank you so much for those that choose to help!
