Piqué and waffle knits have texture that fights even contact. Firm, even pressure and a post-press do the work.
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 any moisture. Our film no longer needs it to bond — but a flat, dry surface still gives the most even contact, 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.
A swing-away or pneumatic press gives the most even pressure over textured knits.
The post-press seats the print down into the weave for a cleaner result.
Keep the design clear of the placket and buttons.
Use a pressing pillow if there's a seam under the print area.
| Symptom | Likely cause | Fix | |
|---|---|---|---|
| Spotty or uneven adhesion | Weave texture caused uneven contact | Use firm, even pressure and a post-press | Adhesion |
| Print sits on top and feels stiff | Not seated into the weave | Post-press with a textured sheet to settle it in | Finish |
Yes. The textured piqué or waffle knit is the only wrinkle — use firm, even pressure (a swing-away or pneumatic press helps) and a post-press to seat the print into the weave.
Keep the design clear of the placket, and use a pressing pillow so buttons and the seam don't create high spots under the platen.
