The most forgiving fabric there is — and with our transfers, it bonds in just 3–5 seconds at a low 280°F.
The number on your press is a suggestion. Presses ship miscalibrated, read differently across the platen, and drift over time — the panel can say 280°F while the print only sees 240°F. What actually bonds a transfer is the print reaching 280°F for 3–5 seconds at firm pressure. So you may need to set your press higher — often 300–310°F — to get there. Dial in your press once, then trust it.
Presses read differently and drift — it's not uncommon for even new heat presses to be off by 20% or more. Answer a few quick questions and we'll get you a good starting point to dial in from.
A 2–3 second tap flattens the garment and drives off moisture. Our film doesn't need it to bond — but a flat, dry surface presses more evenly, so it's worth it in humidity or on a garment that's been sitting.
280°F · 3–5 sec · firm 90 psi. Heat and pressure settle the TPU into the fibers. Hit the number and lift.
Cover the design with a textured sheet and press again. It seats the adhesive deeper for wash durability and gives a softer, matte hand feel. Skip it only for rush or throwaway merch.
| Feel | Pneumatic (psi) | Manual dial (1–9) | What it looks like |
|---|---|---|---|
| Light | 20–40 | 1–3 | Paper slides out easily |
| Medium | 30–50 | 4–5 | Paper drags a little |
| Medium-firm | 40–60 | 5–6 | Firm tug to pull paper |
| Our spec — firm | 90 | 7–9 | Paper won't budge |
On a pneumatic press, set the gauge to 90 psi. On a manual clamshell, aim for a solid two-finger effort to latch, then confirm with the paper-drag test.
Closes at a slight angle, so thick seams take more force at the hinge. Great for flat tees — just latch fully for even contact.
The platen comes straight down for the most even pressure. Best on thick goods like hoodies, denim, and canvas.
Air holds identical pressure every cycle — set 90 psi once and every press matches. Ideal for volume.
Pressing over a pocket or seam? Slip a pressing pillow underneath so the design sits on one flat plane.
Dark cotton with a bright print? The low 280°F keeps the garment dye where it belongs — no migration halo.
Peel in one smooth, low-angle motion the moment the platen lifts — that's what Instant Peel is built for.
Humid shop? A quick pre-press dries the fibers so steam can't undercut adhesion.
| Symptom | Likely cause | Fix | |
|---|---|---|---|
| Edges lift right after peel | Peeled too slowly, or the press didn't reach full pressure | Peel in one smooth motion; confirm 90 psi and a full latch | Adhesion |
| Print looks dull or flat | Under-pressed — platen didn't reach 280°F at the surface | Verify platen temp; add the textured post-press | Finish |
| Design cracks after a few washes | Adhesive never fully seated into the fibers | Add the post-press step; confirm firm pressure | Durability |
| Haze or residue around the art | Moisture trapped in the garment | Pre-press 2–3s to flatten and dry before laying the transfer | Adhesion |
Not with our film — it bonds without it. Pre-pressing mainly gives you a flat, dry surface, which is worth the extra 2–3 seconds in a humid shop or on a garment that feels damp.
Instant Peel: lift the carrier immediately, in one smooth low-angle motion. It's a hot peel — just engineered to release faster and cleaner than a standard one.
Yes — slide a pressing pillow under the print area so it sits on a single flat plane. That keeps pressure even and stops ridges from showing through the design.
Medium-to-hard — a firm two-finger effort to latch. If your press has a gauge, aim for around 90 psi. Use the paper-drag test to calibrate.
Upload a design and our preflight scores how it'll press on cotton — ink density, hand feel, and adhesion, before you order.
