In short
- A UV printer with white + varnish channels prints on A film
- B film (the transfer film) laminates over the print
- The customer peels the A/B sandwich and rubs the sticker onto the surface
How it differs from textile DTF
- Ink: UV-curable, hardened by an LED lamp instead of dried by heat. No powder, no oven, no press.
- Layers: white underbase, colour, and a clear varnish on top that gives the gloss and the scratch resistance.
- Film: two films — A (print) and B (transfer, sticky). The customer applies the sticker; you do not.
- Printer: a UV flatbed or a converted Epson with UV inks and a UV lamp (L1800 / L805 conversions exist, R1390 is common) — not your textile machine.
File preparation
Same as textile: transparent PNG at 300 dpi. Two extras: outline or knockout the design so the varnish has an edge to follow, and avoid hairlines under 0.5 mm — they tear when the customer peels the B film. ZoroPrint’s preflight catches the second one.
Selling it
- Personalised mugs and tumblers are the entry product: no minimum, high margin, ships flat.
- Gang sheets of small logos for gift shops and bars — the same nesting you do for shirts.
- Wall and window decals for local businesses, cut by hand with cut marks on the sheet.
