UV printing

UV DTF

A design is printed onto a film with UV ink and then transferred to an object like a sticker. This also lets you decorate things that do not fit into the printer.

Explained in more detail

DTF stands for Direct to Film. The printer applies colour, white ink and usually varnish to a carrier film (A-film) that already has an adhesive layer, and then a transfer film (B-film) is laminated over it. When applying, you peel off the A-film, press the design onto the object and remove the B-film, leaving only the print without a background. Suitable for curved or awkward objects such as mugs, helmets or tools. Adhesion and abrasion resistance are usually lower than with direct printing on a flatbed, but preparing the object is easier.

Where does the term come from?

DTF is short for the English "Direct to Film". The name originally comes from textile printing, where designs are printed onto film with powder adhesive and ironed on. The prefix UV distinguishes the variant with UV-curing ink and cold transfer.

In practice

  • Arrange several designs on one sheet; this makes better use of the A film and lowers the film cost per piece.
  • Peel the B film back flat and slowly; if the design lifts with it, press it down again with the squeegee.
  • Curved surfaces work well as long as the design is bent in only one direction; with spheres or strong double curves, wrinkles appear.
  • Do not stress the object in the first hours after application, as many adhesives only reach their full hold then.
  • Store laminated sheets dust-free and flat so that the films do not come away at the edges.

Not to be confused

Not to be confused with classic DTF for textiles: that uses powder adhesive and a heat press. UV DTF is stuck on cold and is not intended for clothing.

Frequently asked questions

How long does UV DTF last?

Several years on smooth, clean surfaces indoors. For outdoor use, eufyMake states at least two years without noticeable fading; frequent washing, friction and rough substrates shorten the durability considerably.

Can UV DTF be peeled off again?

Yes, a transfer can usually be peeled off with a fingernail or a plastic scraper, and adhesive residue comes off with isopropyl alcohol. On delicate surfaces, test on an inconspicuous spot first.
