DTF transfers are forgiving, but the press settings still decide whether a print lasts 50 washes or peels at the first one. This guide covers the four things that matter: temperature, time, pressure and peel. It also covers fabric, the second press, and what to do when an edge lifts. Every order from Bayou DTF ships with a press card. If the card and this page ever disagree, follow the card, because it is matched to the film on your order.
Quick settings

What you need
- A heat press with an accurate temperature readout. Clamshell, swing-away and draw presses all work.
- A Teflon cover sheet or parchment paper
- Heat-resistant tape for slick fabrics
- A lint roller
- Your garments and your transfers
Home presses and craft presses can work for small prints. If the press has no pressure gauge, aim for a firm close that you have to lean into, not one that slams shut with no effort.
Step by step
- Set the press. Heat the press to 300–310 °F and set medium-firm pressure. Let the platen reach temperature for at least 10 minutes. Many presses read 10 to 20 degrees off; a cheap infrared thermometer is worth having.
- Pre-press the garment. Press the empty garment for 3–5 seconds to remove moisture and wrinkles. Lint-roll the print area. Moisture trapped in cotton turns to steam and weakens the bond, especially in humid Houston weather.
- Place the transfer. Lay the transfer ink-side down on the garment. Use heat tape on slick fabrics so it cannot shift. Measure placement: on an adult shirt, the top of a full-front print usually sits 3 to 4 inches below the collar.
- Press. Cover with a Teflon sheet or parchment and press for 10–15 seconds.
- Peel. Peel the film in one smooth motion, low and slow, at the temperature the film calls for. Keep the film close to the garment rather than pulling straight up.
- Finish press. Cover the print and press again for 5–10 seconds to set the ink into the fabric and soften the hand. This step makes the print look less like a sticker and more like part of the shirt.
Temperature: why hotter is not better
DTF ink sits on a layer of hot-melt adhesive powder. The press melts the adhesive into the fibers. Too cool, and the adhesive never flows into the fabric, so the print sits on top and lifts in the wash. Too hot, and the ink can glaze, the white base can show through at the edges, and polyester can scorch or bleed dye into the print. Stay inside the range and adjust time before you adjust temperature.
Pressure: the setting most people get wrong
Light pressure is the number-one cause of failed DTF prints. The adhesive needs to be pushed into the weave, not just warmed. If your print has a shiny, raised look and you can see fabric texture around it but not through it, you need more pressure. For thick items like hoodies with seams or zippers under the print area, use a pressing pillow or folded towel inside the garment so the print area sits flat and gets even pressure.
Hot peel versus cold peel
DTF film comes in hot-peel, warm-peel and cold-peel versions. Hot peel means you remove the film within a couple of seconds of opening the press. Cold peel means you wait until the film is completely cool to the touch. Peeling a cold-peel film hot can stretch or tear the print. Peeling a hot-peel film cold can make it stick. The press card in your order tells you which one you have.
Fabric notes
- Cotton and cotton blends: the easiest fabrics for DTF. Use the standard settings.
- Polyester and performance wear: lower temperature and time. Test on one garment first, because some dyed polyester migrates color into the white ink.
- Nylon and coated fabrics: test first. Some jackets and bags have water-repellent coatings that block adhesion.
- Canvas, denim and totes: add 2 to 3 seconds of press time and firm pressure.
- Hats: use a hat press or a curved platen and press in sections for small front logos.
Troubleshooting
Edges lift after peeling. Lay the film back down if you can, or use a cover sheet, and press again for 10 seconds with more pressure.
Print cracks after washing. Usually too much heat, a garment washed too soon, or a dryer set to high. Wait 24 hours before the first wash.
Film will not release. You may be peeling at the wrong temperature. Check the card. Let it cool fully, then try again slowly.
Shiny print. Do the finish press with a textured cover like a cotton cloth or matte Teflon for a softer, matte look.
Care card for your customers
If you sell what you press, include these care steps: wait 24 hours before washing, turn the garment inside out, wash cold, tumble dry low or hang dry, and never iron directly on the print. Following them is what gets a DTF print to last as long as the shirt.

Common questions
Can I press DTF transfers with a household iron?
Yes for small designs, but a heat press gives far better results. An iron cannot hold even heat and pressure across a large transfer, so edges often lift. If you use an iron, use the cotton setting with no steam, press each section for 15–20 seconds with firm body weight, and do not slide the iron.
Why is my DTF transfer peeling off after washing?
Almost always low pressure, low temperature or too short a press. Re-press the garment for 10 seconds under a cover sheet. Also wait 24 hours before the first wash and wash inside out in cold water.
Hot peel or cold peel?
It depends on the film. Follow the peel instruction on the press card that comes with your order. Peeling at the wrong temperature is the most common cause of a transfer pulling up with the film.
Can DTF go on 100% polyester?
Yes. Lower the temperature to around 275–285 °F and shorten the press to avoid dye migration and scorch marks on performance fabric.
