DTF stands for direct-to-film. The design is printed onto a clear PET film, coated with a powdered adhesive, cured, and shipped to you as a transfer. You press it onto a garment with heat, peel the film, and the ink stays. That’s the whole process — here’s what’s actually happening at each step, and why it matters when you’re the one holding the press.
How a DTF transfer is made
- Print. A DTF printer lays water-based pigment ink onto the film — CMYK first, then a layer of white ink over the top of it. The white is printed last because the film is pressed face-down, so on the shirt the white ends up underneath the colour. That white underbase is why a DTF transfer looks the same on a black shirt as on a white one.
- Powder. While the ink is still wet, the film passes through a bed of hot-melt adhesive powder. It sticks only where there’s ink. That’s why the background of your file has to be transparent: anything with ink gets adhesive, anything without gets nothing.
- Cure. The powdered film goes through an oven that melts the powder into a smooth adhesive layer and dries the ink. It comes out as a flat, slightly rubbery transfer that can sit in a drawer for a year.
- Press. You lay it ink-side down on the garment, press at 300°F for 12 seconds, let it cool, and peel the film. The adhesive has bonded to the fibres; the ink comes with it.
What it means in practice
Any fabric colour, no extra step
Screen printing a bright design on a black shirt needs a white underbase screen and a second pass. Sublimation doesn’t work on dark or cotton garments at all. DTF has the white built in, so a red logo on black cotton and a red logo on white poly are the same transfer, pressed the same way.
Almost any fabric
Cotton, polyester, blends, tri-blends, canvas, denim, fleece, nylon, most performance fabrics. The adhesive bonds to fibre, not to a chemical in the fabric, which is the difference from sublimation. The exceptions are few: some coated nylons, and anything that can’t take 280°F.
No minimums, because there are no screens
Screen printing costs the same to set up whether you print one shirt or five hundred, so shops set minimums. DTF has no setup — the printer just prints the file. One transfer costs one transfer. That’s why a single 2-inch sample is a real order here.
Full colour, photographic if you want
Gradients, photos, hundreds of colours — it’s an inkjet process, so complexity is free. A one-colour logo and a full-colour painting cost the same per inch.
The feel
Pressed right, a DTF transfer has a thin, slightly rubbery hand — more than a water-based screen print, less than a vinyl. The second press through parchment matters here: it pushes the ink into the fibre and knocks down the sheen. Skipped, the transfer sits on top of the shirt and feels like a sticker.
What DTF is not good at
Very large solid areas — a full-back block of colour — feel heavy, because the whole area is a layer of ink and adhesive. Screen printing or a soft-hand water-based ink does that job better. Neon and fluorescent colours print duller than they look on screen; there’s no fluorescent ink in the process. And very fine hairlines under 1 pt can drop out, because the powder needs enough ink to grab.
Durability
Pressed at the right settings with a cold peel and a second press, a DTF transfer outlasts most of the garments it’s on — 50+ washes without cracking is normal. Peeled warm and pressed once, it cracks in five. The process is forgiving of almost everything except the peel. Press guide.
Gang sheets
Because the printer prints a roll, you can put as many designs as you like on one sheet — different sizes, different artwork — and pay by the inch of roll used, not per design. That’s a gang sheet, and it’s how the price of a single transfer gets down to a dollar or two. How to lay one out.
