Temperature, time and pressure change by fabric, not by transfer. Here is the chart we actually use on the shop floor, fabric by fabric.
Every DTF transfer is the same film with the same adhesive. What changes is the garment underneath it, and that's what actually decides your temperature, dwell time and pressure. Press a hoodie like a t-shirt and you'll scorch the fleece or under-melt the adhesive. Press a nylon jacket like cotton and you'll warp the fabric before the adhesive even sets. This is the chart we run at our own presses in Regina, fabric by fabric, with the reasoning behind each number.
| Fabric | Pre-press | Press temp | Press time | Pressure | Peel | Second press |
|---|---|---|---|---|---|---|
| 100% cotton | 5 sec | 290°F / 143°C | 8 sec | Medium-firm | Warm | 8 sec, Teflon |
| 50/50 poly-cotton | 5 sec | 275°F / 135°C | 8 sec | Medium-firm | Warm | 8 sec, Teflon |
| 100% polyester | 3 sec | 265°F / 129°C | 10 sec | Medium | Warm | 8 sec, Teflon |
| Performance / moisture-wicking | 3 sec | 260°F / 127°C | 10 sec | Light-medium | Warm | 6 sec, Teflon |
| Tri-blend | 5 sec | 270°F / 132°C | 8 sec | Medium | Warm | 8 sec, Teflon |
| Nylon | 3 sec | 250°F / 121°C | 12–14 sec | Light | Cold | 6 sec, low pressure |
| Canvas / tote bags | 5 sec | 290°F / 143°C | 8 sec | Firm | Warm | 8 sec, Teflon |
| Fleece / hoodie | 5 sec | 275°F / 135°C | 10 sec | Medium-firm | Warm | 8 sec, Teflon |
| Hats (structured) | 3 sec, curved attachment | 270°F / 132°C | 10–12 sec | Firm, even | Warm | 6 sec |
Every heat press reads slightly differently than its display, and every fabric blend from every mill behaves a bit differently. Use these numbers as your dial-in point, then run a test press on a scrap or an inside seam before you commit to the real order.
The adhesive on a DTF film needs to reach a melt point and stay there long enough to bond into the fibres — that part doesn't change. What changes is how much heat a fabric can take before it scorches, yellows, shines or shrinks, and how much heat a fabric conducts through to the adhesive layer in the first place. Thick cotton absorbs heat slowly and tolerates a lot of it. Thin synthetic knits heat up fast and scorch, melt or dye-migrate long before cotton would even notice.
That's the whole logic behind the chart above: natural fibres get more heat and more time, synthetics get less heat and slightly more time to compensate, and anything with dye that can migrate (polyester, especially dark colours) gets pushed to the low end of its range.
A 3–5 second pre-press with no transfer on the garment does two things: it flattens wrinkles that would otherwise trap air under the film, and it drives out moisture. Moisture is the single most common cause of a transfer that looks perfect coming off the press and then bubbles or lifts at the edges an hour later. Blanks that have been sitting in a humid warehouse or shipped in plastic need this step more than fresh-off-the-dryer garments.
Most clam-shell and swing-away presses don't give you a real number, just a dial or a lever tension — so use the paper test. Slide a sheet of printer paper under the platen and close the press. You should feel firm, even resistance across the whole sheet, not a gap on one side. Too light and the adhesive never fully contacts the fibres, which shows up later as edges lifting. Too heavy and you'll get shine on the garment or, on thinner knits, a visible platen imprint.
The easiest and most forgiving fabric to press. 290°F for 8 seconds at medium-firm pressure bonds cleanly almost every time. Ringspun and combed cottons take the heat evenly; heavier fleece-lined cotton needs the full 8 seconds to let heat reach through to the adhesive.
Poly-cotton blends split the difference — drop 5°F from straight cotton to protect the poly content from scorching, keep the same dwell time. Tri-blends (cotton/poly/rayon) are the softest and most heat-sensitive of the blend family; rayon in particular can shine or crush under too much pressure, so back off to medium and watch your first test press closely.
This is where dye migration becomes the real risk, not scorching. Dark polyester jerseys — especially reds and navies — can bleed dye up through the adhesive layer under too much heat, discolouring the print itself over the following day or two. Press cooler (260–265°F), a touch longer to compensate, and lighter pressure. If you're running a lot of dark athletic polyester, it's worth reading our full breakdown of migration-proofing on polyester and nylon.
Nylon has the lowest melting point of anything on this chart — push past 260°F and you risk visible glazing or the fabric itself going stiff and shiny under the platen. Press at 250°F for longer (12–14 seconds) with light pressure, and always cold peel. Warm peeling nylon before the adhesive fully sets is the number one cause of edge lift on jacket orders.
Canvas is thick, dense and tolerant of heat, but the weave itself can be uneven, so it needs firm, even pressure and the longest dwell time on the chart to make sure heat gets all the way through to the adhesive sitting in the weave gaps. An 8-second press at 290°F with firm pressure is standard for a 10oz cotton tote.
Fleece traps air in its nap, which insulates the surface and can fool you into thinking the transfer has bonded when the adhesive underneath hasn't fully melted. Press slightly longer than a plain cotton tee (10 seconds) and consider a lighter pre-press pass to compress the nap first so the platen makes full, flat contact with the printed area.
Structured caps need a curved attachment on your press, not a flat platen, or you'll bond only the crown of the arch and leave the sides unpressed. Pressure needs to be firm and even across the curve — this is the one place where a bad platen fit will ruin an otherwise correct temperature and time. Panel seams are a weak point; press over them carefully and check the edges before pulling the cap off.
Whether it's chest logos for tees or small marks for hat panels, lay it all out on one sheet and we'll ship it from Regina in 1–2 business days.
Warm peel — pulling the film within a few seconds of lifting the press, while the garment is still hot — is correct for cotton, blends, canvas and fleece. Cold peel — letting the piece cool fully before pulling the film — is correct for nylon and gives cleaner results on some performance polyesters too. Peeling too early on a fabric that wants a cold peel is the most common reason a print looks fine off the press and then shows white specks or partial lift once it cools.
After peeling, lay a Teflon sheet or parchment over the print and press again for 8 seconds at the same temperature with medium pressure. This drives the adhesive fully into the fibres, knocks down any texture in the film, and is genuinely the difference between a transfer that survives 10 washes and one that survives 50. Skip it on a tight timeline if you must, but don't skip it on anything going out the door to a paying customer.
290°F for 8 seconds at medium-firm pressure with a warm peel covers 100% cotton and most 50/50 blends, which is the majority of orders. Everything else on this page is an adjustment away from that baseline.
Almost always trapped moisture or air. Pre-press the blank for 3–5 seconds with no transfer on it first, and make sure your pressure is even across the platen — a light spot is enough to trap a pocket of air under the film.
No. An iron cannot hold consistent temperature or pressure, so times need to roughly double and you should press through the garment (inside out) rather than directly on the transfer. A real heat press is worth the investment if DTF is more than an occasional project.
Above about 270°F, dark polyester dyes start to migrate up through the adhesive and can discolour the print over the following day. Stay at 260–265°F on polyester, especially on saturated colours like red, navy or maroon.
It's strongly recommended, not optional if you want the print to hold up. An 8-second post-press with a Teflon sheet finishes bonding the adhesive and noticeably improves wash durability.
Almost always a platen fit issue. A curved cap attachment applies pressure unevenly if the hat isn't seated correctly or the crown height doesn't match the attachment — check contact across the whole design before pulling the cap.
The fabric is the same, so the settings don't change — but heavier fabric in bigger sizes can take slightly longer to heat through evenly. Add a second or two to the dwell time on plus-size cotton and fleece pieces if you notice inconsistent adhesion.
