I’ve been casually trying to create better quality stickers at home over the years trying to replicate what you get at the professional sticker shops. Aside from UV protection, I think I’ve gotten pretty close. I probably have to switch to an archival pigment ink for better UV protection but that might require me to buy a different printer. These stickers are waterproof vinyl with a matte cover finish. I think they look pretty good!
Ted Cannon@mark those do look great! do you have tips and tricks for beginners?
@Teddro I've been using an Epson Ecotank printer to print on glossy vinyl sticker sheets (the thicker the better), and cutting them with a cricut after I layer a matte transparent sticky vinyl over it.
eric@mark what kind of vinyl sheets are you using?
