DTF PRESS GUIDE
How to press your DTF gang sheet, properly.
Everything you need from upload to finished garment. Heat press temperatures by fabric, peel timing, aftercare, troubleshooting, and answers to every question we've ever been asked. Save this page — it's the only DTF instructions you'll need.
Set up your design files correctly.
DTF prints are unforgiving — what you upload is what we print. Get the file right and you'll get crisp, vibrant, durable prints every time.
01.01
Use CMYK colour mode
Set your file's colour profile to CMYK for the most accurate colour reproduction. RGB files often print darker or with shifted hues because our printers convert them on the fly.
How: In Photoshop go to Image → Mode → CMYK Color. In Illustrator: File → Document Color Mode → CMYK.
01.02
Export at 300 DPI minimum
Anything under 300 DPI will look soft or pixelated on a t-shirt. For small detailed designs, push to 600 DPI.
Quick check: Your design at print size (e.g. 25 × 25 cm) should be at least 2953 × 2953 px.
01.03
Save as PNG with transparency
Accepted formats: PNG (preferred), JPG, PDF, AI, EPS, SVG. PNG with a transparent background gives you the cleanest result — anywhere there's no design, no ink prints.
Avoid JPG unless your design is a full-bleed photo with a square edge.
01.04
Remove the background
If your file has a white or coloured background you don't want printed, remove it. Our builder includes AI background removal — one click and it's done.
Or upload as-is and we'll show you a preview before printing.
01.05
Outline your strokes and text
Convert all strokes and text to outlines so font substitutions never happen:
- Illustrator: Object → Path → Outline Stroke
- Illustrator text: Type → Create Outlines
- Photoshop: Rasterise or flatten the text layer
01.06
Do NOT mirror your design
Upload your design right-reading — exactly how it should look on the finished garment. Our printer mirrors it automatically when printing on film.
If you mirror in your file AND we mirror at print, you'll end up with a reversed, unreadable transfer.
01.07
Use halftones for fades
DTF can't print semi-transparent pixels. A 50% transparent area will either print at full opacity or not at all — unpredictable.
Fix: Convert gradients and fades to halftone dots in Photoshop (Filter → Pixelate → Color Halftone) or Illustrator.
01.08
Mind the small details
Lines thinner than 0.5 mm and text smaller than 4 pt may not print reliably. Bulk up thin strokes and increase tiny text where possible.
01.09
White underbase — we handle it
You don't need to add a white underbase layer. Our printer automatically prints white ink under colour so your design shows up vivid on dark fabrics.

Inspect, store, and prepare.
A 60-second check now saves a ruined garment later. Here's exactly what to do when your DTF transfers land on your doorstep.
CHECK
Inspect within 24 hours
Open the package and check the print quality matches your order. Look for missing white ink, cracked surface, or transit damage. Any issues — message us within 24 hours of receipt for a free reprint.
STORE
Store flat, cool, and dry
Keep transfers flat in their original packaging until you're ready to press. Avoid direct sunlight, damp areas, and temperatures over 30 °C — the adhesive layer can soften prematurely.
Shelf life when stored correctly: up to 12 months.
CUT
Trim around each design
Use sharp scissors or a craft knife to cut around each transfer, leaving a 2–3 mm border. Don't trim too tight or you risk cutting into the print edge.
TEST
Press a test square first
Before pressing a full design onto an expensive garment, press a small test piece on a fabric scrap. This confirms your press temperature, timing, and pressure are dialled in.
Get your equipment dialled in.
DTF needs accurate temperature, even pressure, and consistent timing. A cheap iron won't cut it for production-quality results.
EQUIP
Use a proper heat press
A flat-bed clam or swing-away heat press is essential. Don't use a household iron — it can't deliver even pressure or accurate temperature.
Recommended brands: Stahls Hotronix, Adkins, Galaxy, Geo Knight.
TEMP
Verify your press temperature
Cheap presses lie. Check the actual platen temperature with a laser thermometer — many run 10–20 °C cooler than the dial reads.
Adjust your set temperature to match the recipe in Step 6.
PRESS
Set firm, even pressure
DTF needs 55–70 PSI / "firm" pressure. Test by placing a fiver under one corner of the platen at full close — if you can't pull it out, you've got firm pressure.
PREP
Pre-press the garment
Press your blank garment for 3–5 seconds before applying the transfer. This removes moisture and wrinkles that ruin adhesion.
COVER
Use a Teflon sheet or parchment
Always cover the transfer with a Teflon sheet, silicone pad, or parchment paper before pressing. Protects the press platen and gives a cleaner finish.
PLACE
Position transfer film-up
Place your trimmed transfer on the garment with the printed image facing up, film side up. The clear film should be touching the press platen (via the Teflon sheet).
Press settings by fabric type.
The recipe depends on what you're pressing onto. Use this table — it's the result of thousands of hours of testing across every fabric we've ever seen.
HEAT PRESS RECIPES°C / SECONDS / PSI
| Fabric | Temperature | Press time | Pressure | Peel |
|---|---|---|---|---|
| 100% Cotton | 155–160 °C | 13–15 sec | 55–65 PSI | Cold peel |
| Polycotton blend (50/50) | 150–155 °C | 12–14 sec | 55–65 PSI | Cold peel |
| 100% Polyester | 130–135 °C | 8–10 sec | 50–60 PSI | Cold peel |
| Nylon | 130 °C | 8–10 sec | 50–60 PSI | Cold peel |
| Spandex / Lycra | 130 °C | 8 sec | 50 PSI | Cold peel |
| Hi-vis / Workwear | 135 °C | 10 sec | 55 PSI | Cold peel |
| Canvas / Tote bags | 155 °C | 15 sec | 65 PSI | Cold peel |
| Caps (cap press required) | 155 °C | 12 sec | 60 PSI | Cold peel |
| Towels (terry cloth) | 160 °C | 18 sec | 70 PSI | Cold peel |
The exact press sequence
01
Pre-press the blank
3–5 seconds at your target temperature. Removes moisture and wrinkles.
02
Position the transfer
Image facing up, film up. Cover with Teflon sheet or parchment.
03
First press
Apply heat, time, and firm pressure per the recipe table.
04
Cold peel
Wait 15–30 seconds until the film is at room temperature, then peel slowly from one corner.
05
Post-press
Re-press the design for 5–8 seconds through a Teflon sheet. Locks in durability and wash resistance.
!
The post-press is non-negotiable
Skip the post-press and your prints will crack and peel after a few washes. The second press seals the edges and bonds the print fully to the fabric. Every print, every time.
i
Cold peel always — for DTF Mates film
Our PET film is engineered for cold peel. Hot-peeling will distort fine detail and leave a sticky residue. Wait until you can touch the film comfortably with bare fingers, then peel in one smooth motion from a corner.
Make your prints last 50+ washes.
Pressed correctly and washed correctly, DTF prints outlast the garment itself. Here's what to tell your customers.
WAIT
Wait 24 hours before first wash
Give the adhesive a full day to cure after pressing. Washing too early weakens the bond.
TEMP
Wash inside-out at 30 °C max
Turn the garment inside-out before washing. Use a gentle or normal cycle at 30 °C. Hotter water shortens print life.
DETERGENT
No bleach or fabric softener
Use a mild liquid detergent. Avoid powder detergents with optical brighteners, bleach, and fabric softeners — they all degrade DTF prints.
DRY
Tumble low or air dry
Tumble dry on low heat, or hang to air dry. Avoid high-heat tumble drying — it can soften the adhesive.
IRON
Never iron directly on the print
If you must iron, iron the back of the garment or place a thin towel over the design. Direct iron contact can scorch the print.
DRY-CLEAN
Don't dry clean
The solvents used in dry cleaning will dissolve the adhesive layer. Hand wash or machine wash only.
When something goes wrong.
Every DTF problem we've ever seen, and exactly how to fix it. Bookmark this section.
PROBLEM 01
Film won't peel cleanly off the garment
The print is sticking to the film instead of the fabric, or the film is leaving a sticky residue.
Fix: You're peeling too hot. Wait until the film is fully at room temperature (15–30 sec) before peeling. If it's still sticky, your press temperature is too low — increase by 5 °C.
PROBLEM 02
Print cracks or peels after a few washes
Design starts to lift, crack, or flake after 1–5 wash cycles.
Fix: You almost certainly skipped the post-press. Re-press finished garments for 5–8 sec through a Teflon sheet. Also check washing instructions — high heat washing or fabric softener accelerates print failure.
PROBLEM 03
White underbase showing around the design edge
You can see a white halo around the printed design after pressing.
Fix: The white ink layer is wider than the colour layer — this is a file issue, not a press issue. Re-export your design with a 1 px choke on the white channel, or message us and we'll fix the file for you.
PROBLEM 04
Print looks faded or washed out after pressing
Colours are dull compared to the digital file.
Fix: You're pressing too long or too hot. Drop temperature by 5 °C and time by 2 sec. Also confirm your design was in CMYK before upload — RGB files often print darker.
PROBLEM 05
Print has a shiny or glossy finish you don't want
The design comes out glossy when you wanted matte.
Fix: Post-press with a textured silicone pad or coarse parchment paper instead of smooth Teflon. The texture transfers to the print surface, giving a matte finish.
PROBLEM 06
Adhesive residue / sticky feel after pressing
The pressed area feels tacky or has visible adhesive residue.
Fix: You hot-peeled instead of cold-peeled. Increase your peel wait time to 30 seconds. The adhesive needs to fully cool before separating from the fabric.
PROBLEM 07
Fabric is scorched or shiny next to the design
Visible press marks or scorching outside the design area.
Fix: Your press temperature is too high for the fabric, or you're pressing too long. Drop to the lower end of the recipe range. For delicate fabrics, use a press cloth or lower-temperature DTF process.
PROBLEM 08
Design has uneven coverage — some parts didn't transfer
Patches of the design failed to transfer to the garment.
Fix: Uneven pressure or moisture in the fabric. Pre-press the garment longer to remove moisture, check your press pressure is firm and even across the platen, and re-press the failed area for an extra 5 seconds.
PROBLEM 09
Bleeding or wicking on polyester sportswear
Colours from the polyester garment are bleeding into the white underbase of the print.
Fix: Polyester sublimation dyes activate above 130 °C — they migrate up into your print. Use a poly-blocker spray on the garment before pressing, drop temperature to 125–130 °C, and use a longer press time (12 sec) to compensate.
PROBLEM 10
Design comes off completely on first wash
Whole print lifts and washes away.
Fix: Either your press temperature was way too low, pressure was insufficient, or you skipped post-press. Re-test with a temperature 10 °C higher, confirm firm pressure (fiver test), and always post-press 5–8 sec.

FREQUENTLY ASKED
Every question, answered.
If you're wondering about it, the answer is here. If not, message us and we'll add it.
What is DTF printing?
DTF — Direct to Film — is a heat-transfer printing process where your design is printed onto a special PET film with a white ink underbase, then heat-pressed onto fabric. Unlike sublimation, it works on any fabric colour. Unlike vinyl, you can print full-colour photo-realistic designs. Unlike screen printing, there's no setup cost — order one transfer or a thousand.
How is DTF different from sublimation, vinyl, and screen printing?
vs Sublimation: Sublimation only works on white or light polyester. DTF works on any fabric, any colour, including 100% cotton.
vs Vinyl (HTV): Vinyl is single-colour or layered. DTF is full-colour photo-quality with no weeding needed.
vs Screen printing: Screen printing is cheaper per unit at high volume (500+) but needs separate screens per colour. DTF is on-demand, full-colour, no setup.
What fabrics can I press DTF onto?
Almost anything: 100% cotton, polycotton, polyester, nylon, spandex, hi-vis workwear, canvas, denim, fleece, terry towels, jersey, ribbed knits. Each has its own ideal temperature and time — see the recipe table in Step 6.
Avoid: Waterproof or PU-coated fabrics, anything labelled "do not iron," and ultra-fine silk or satin without testing first.
What heat press do I need?
Any flat-bed heat press capable of reaching 160 °C with firm, even pressure. Avoid household irons — they don't apply even pressure and most don't hold temperature accurately enough for production work.
Budget options: Vevor, Hix. Professional: Stahls Hotronix Auto-Open, Adkins, Galaxy. For caps you'll need a curved cap press.
Can I use an iron instead of a heat press?
Technically yes, but the results will be inconsistent. Irons can't deliver the even pressure or precise temperature DTF needs. For a one-off home project it may work; for selling garments commercially, invest in a proper heat press.
How long do DTF prints last?
Pressed correctly (with the post-press step) and washed correctly (inside-out, 30 °C, no softener), DTF prints last 50+ wash cycles without visible degradation. The print typically outlasts the garment fabric itself.
Are DTF prints stretchy?
Yes — modern DTF films are flexible and stretch with the fabric. They're suitable for sportswear, leggings, t-shirts, and anything else that needs to move with the body. Avoid extreme stretch (over 50% elongation) like dance leotards where vinyl might be better.
Do DTF prints feel rubbery or plastic?
Modern DTF has a soft, slightly raised feel — much softer than older plastisol screen prints or vinyl. After 1–2 washes the print softens further and integrates with the fabric. It's noticeable but not uncomfortable.
What's the cheapest way to order DTF transfers?
Buy in meterage rather than individual A3/A4 sheets. Our 56×500 cm gang sheet works out to £9.95 per metre — the lowest price per cm² we offer. Use our builder's Auto Fill to pack the sheet tight with multiple designs.
Can I order one-off custom prints?
Yes — there's no minimum. Order a single A4 sheet with one design, or fill a 5-metre sheet with hundreds. Same quality either way.
Do you offer next-day or same-day delivery?
Yes. All orders placed before 1 PM UK time ship the same working day. Royal Mail Tracked 24 (£3.95) usually delivers next day. Royal Mail Special Delivery by 1 PM (£9.95) is guaranteed next working day before 1 PM.
Need it sooner? Email us about urgent print collection at our Rochester workshop.
What file types do you accept?
Preferred: PNG with transparent background, at least 300 DPI.
Also accepted: JPG, PDF, AI, EPS, SVG, PSD (flattened).
Max file size: 50 MB per upload via the builder.
Do I need to mirror my design before uploading?
No. Upload your design right-reading — exactly as you want it to appear on the finished garment. Our printer automatically mirrors it during printing onto the PET film.
What's the maximum print size?
Our largest single sheet is 56 × 500 cm (5 metres of meterage). Individual designs can be up to 56 cm wide and as tall as the sheet allows. For larger formats, contact our bulk team.
Can I get a refund if I'm not happy?
Yes. If your prints arrive damaged, with missing white ink, or don't match what was previewed in the builder, we'll reprint or refund — no questions asked, within 14 days of receipt.
If you upload a poor-quality file and it prints exactly as supplied, we can't refund — but our resolution check will warn you before you order, and our team will happily fix files for you, free, before printing.
Do you ship internationally?
Currently UK only via standard tracked shipping. For Republic of Ireland, EU, and international wholesale, email international@dtfmates.com.
Can DTF be applied to caps and hats?
Yes, but you'll need a curved cap press. Temperature 155 °C, time 12 sec, firm pressure. The cap structure prevents using a flat heat press effectively.
What about polyester sportswear and dye migration?
Polyester dyes activate above 130 °C and can migrate into your white underbase, especially with red, navy, and black garments. Solutions: use a poly-blocker spray, press at the lower end of the recipe (130 °C / 10 sec), or use sublimation-blocker DTF film for guaranteed results.
Will DTF work on leather, wood, or hard surfaces?
DTF is designed for fabric. For leather, faux leather, wood, acrylic, ceramics, and other rigid surfaces, use UV-DTF — a different process that doesn't need heat. We don't offer UV-DTF yet but it's on the roadmap.
How do I store DTF transfers before pressing?
Flat, in their original packaging, away from direct sunlight, in a cool dry place (under 25 °C, under 60% humidity). Stored correctly, our transfers last 12 months with no loss of quality.
Can I press multiple designs in one go?
Yes — cut each design out of the gang sheet, position multiple designs on the garment, cover all with one Teflon sheet, and press. The recipe (temp/time/pressure) is the same as pressing a single design.
Why are my prints peeling after washing?
Most common cause: you skipped the post-press. Re-press finished garments for 5–8 sec through a Teflon sheet to seal the print. Other causes: washing too hot, using fabric softener, low press temperature, insufficient pressure, hot-peeling instead of cold-peeling.
How do I know if my heat press has enough pressure?
The £5 note test: place a five-pound note (or any thin paper) under the corner of the platen at full close. Try to pull it out. If it doesn't budge, you have firm pressure. If it slides out easily, increase pressure.
Does the colour I see on screen match what I'll get printed?
Close, but not exact. Screens are RGB and self-illuminated; print is CMYK and reflective. For brand-critical colour matching, send us a Pantone reference or sample. For general designs, work in CMYK and you'll get a 95%+ accurate match.
Do you offer help with poor-quality artwork?
Yes. Upload anything to the builder and our resolution check tells you instantly if it's print-ready. For files that need work, our team offers free background removal and basic touch-ups. For full design work — recreating from a photo, vectorising a sketch — message us for a quick quote (usually £10–25).
