PrintMetWit is one of the few providers of a print service on decal paper and sticker material in color and with white. Where many printers and print shops can only print colors, printing can be done here with white as a standalone color or as a spot color. You can print on various media such as waterslide decal paper, sticker materials, tattoo paper and much more.
I once started a webshop in the sale of special media for printing and other hobby and small business purposes (paperspecials.nl). Now I have taken a new path with a print service for special media, with and without white printed from print-ready files. Possibly even studio work can be done, if you cannot draw / compile the files yourself.
