HEAT PRESS GUIDE
How to apply your DTF transfers.
Everything from artwork upload to finished garment. Heat press recipes by fabric, peel timing, aftercare, troubleshooting — every question we've ever been asked, answered. Bookmark this page.
01Artwork prep
Get your files right.
DTF prints exactly what you upload. Spend 10 minutes setting your file up properly and you'll get crisp, vibrant, durable prints every time.
RULE 01
Set CMYK colour mode
Set your file's colour profile to CMYK for the most accurate printed colour. RGB files print darker or with shifted hues.
How: Photoshop → Image → Mode → CMYK. Illustrator → File → Document Color Mode → CMYK.
RULE 02
Export at 300 DPI minimum
Anything under 300 DPI looks soft on fabric. For small detail, push to 600 DPI.
Quick check: A 25 × 25 cm print needs at least 2953 × 2953 px.
RULE 03
PNG with transparency
Best: PNG with transparent background. Also accepted: JPG, PDF, AI, EPS, SVG. Avoid JPG unless it's a full-bleed photo.
RULE 04
Remove the background
Any white or coloured background you don't want printed must come off. Our builder has AI background removal — one click, done.
RULE 05
Outline strokes & text
Convert all strokes and text to outlines so fonts never substitute.
- Illustrator: Object → Path → Outline Stroke
- Illustrator text: Type → Create Outlines
- Photoshop: Rasterise the text layer
RULE 06
Do NOT mirror
Upload right-reading — exactly how it should look on the finished garment. Our printer mirrors it for film printing. Mirror it yourself and we'll mirror again — backwards print.
RULE 07
Halftones for fades
DTF can't print semi-transparent pixels. Convert gradients and fades to halftone dots before exporting.
Photoshop: Filter → Pixelate → Color Halftone.
RULE 08
Mind small details
Lines under 0.5 mm and text under 4 pt may not print reliably. Thicken thin strokes and bump tiny text.
RULE 09
White underbase = handled
You don't need to build a white layer. Our printer prints white ink under your colours automatically so designs pop on dark fabrics.

04When prints arrive
Inspect, store, prep.
A 60-second check now saves a ruined garment later. Here's exactly what to do when your DTF transfers land.
CHECK
Inspect within 24 hours
Open the package and check prints match your order. Look for missing white ink, cracking, or transit damage. Any issues — message us within 24 hours for a free reprint.
STORE
Flat, cool, dry
Keep transfers flat in original packaging until ready to press. Avoid direct sun, damp, and over 30 °C — the adhesive can soften.
Shelf life when stored right: 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 test piece on a scrap. Confirms your press temperature, timing, and pressure are dialled.
05Heat press setup
Dial in your equipment.
DTF needs accurate temperature, even pressure, and consistent timing. A cheap household iron won't deliver production-quality results.
EQUIP
Use a proper heat press
A flat-bed clam or swing-away heat press is essential. Skip the iron — it can't deliver even pressure or hold accurate temperature.
Brands we like: Stahls Hotronix, Adkins, Galaxy, Geo Knight.
TEMP
Verify press temperature
Cheap presses lie. Check actual platen temp with a laser thermometer — many run 10–20 °C cooler than the dial. Adjust set temp to match the recipe.
PRESS
Firm, even pressure
DTF needs 55–70 PSI / "firm" pressure. Test: place a fiver under one corner of the platen at full close. If you can't pull it out, pressure is firm enough.
PREP
Pre-press the garment
Press your blank garment for 3–5 seconds before applying the transfer. Removes moisture and wrinkles that wreck adhesion.
COVER
Use Teflon or parchment
Always cover the transfer with a Teflon sheet, silicone pad, or parchment paper. Protects the platen and gives a cleaner finish.
PLACE
Position film-up
Place your trimmed transfer with the printed image facing up, film side up. Clear film touches the press platen via the Teflon sheet.
06Heat, time, pressure
Press settings by fabric.
The recipe depends on what you're pressing. This table — built from thousands of hours of testing across every fabric we've ever seen.

Pre-press blank
3–5 seconds at target temp. Removes moisture and wrinkles.
2
Position transfer
Image facing up, film up. Cover with Teflon or parchment.
3
First press
Apply heat, time, and firm pressure per the recipe.
4
Hot peel
Peel within 3–5 seconds while film is still warm. Smooth, single motion.
5
Post-press
Re-press for 5–8 sec through Teflon. Locks durability.
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.
Hot peel — always — for DO IT DTF film
Our PET film is engineered for hot peel. Peel within 3–5 seconds of opening the press, while the film is still warm. Wait too long and the adhesive sets — film cools, sticks, and pulls at the print edges. Smooth, single motion from a corner.
07Aftercare
Make prints last 50+ washes.
Pressed right, washed right, DTF prints outlast the garment itself. Here's what to tell every customer who buys from you.
WAIT
24 hours before first wash
Give the adhesive a full day to cure after pressing. Washing too early weakens the bond.
TEMP
Inside-out at 30 °C max
Turn the garment inside-out. Gentle or normal cycle at 30 °C. Hotter water shortens print life.
CLEAN
No bleach or softener
Mild liquid detergent only. 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, or hang to air dry. High-heat tumble drying can soften the adhesive.
IRON
Never iron directly
If you must iron, iron the back of the garment or put a thin towel over the design. Direct iron contact scorches the print.
NO DRY-CLEAN
Skip dry cleaning
Dry-cleaning solvents dissolve the adhesive. Hand wash or machine wash only.
SOSTroubleshooting
When something goes wrong.
Every DTF problem we've ever seen, with the exact fix. Bookmark this — it'll save your job.
Problem 01
Film won't peel cleanly
The print sticks to the film instead of fabric, or the film leaves a sticky residue.
Fix — You waited too long. Hot peel means peeling IMMEDIATELY (within 3–5 sec) while film is still warm. Missed the window? Re-press for 2 sec, then peel hot. Still failing? Press temperature is too low — increase by 5 °C.
Problem 02
Print cracks after washing
Design lifts, cracks, or flakes after 1–5 wash cycles.
Fix — You almost certainly skipped the post-press. Re-press garments for 5–8 sec through Teflon. Also check wash care — high heat and softener accelerate failure.
Problem 03
White halo around design
You can see a white ink edge around the printed design after pressing.
Fix — White ink layer is wider than the colour layer — file issue, not press. Re-export with a 1 px choke on the white channel, or message us and we'll fix it.
Problem 04
Colours look faded
Print looks dull compared to your digital file.
Fix — You're pressing too long or too hot. Drop temperature by 5 °C and time by 2 sec. Confirm your design was in CMYK — RGB often prints darker.
Problem 05
Glossy when you wanted matte
The design comes out shiny.
Fix — Post-press with a textured silicone pad or coarse parchment paper instead of smooth Teflon. The texture transfers to the print surface, giving matte.
Problem 06
Sticky residue after pressing
Pressed area feels tacky or has visible adhesive residue.
Fix — Your press temperature is too low — the adhesive didn't fully cure. Increase press temp by 5–10 °C. Always finish with the 5–8 sec post-press through Teflon to fully bond.
Problem 07
Fabric scorched next to design
Visible press marks or scorching outside the design area.
Fix — Press temperature too high for the fabric, or too long. Drop to the lower end of the recipe range. For delicates, use a press cloth.
Problem 08
Uneven coverage — patches missed
Patches of the design failed to transfer.
Fix — Uneven pressure or moisture in fabric. Pre-press longer to remove moisture, check pressure is firm and even across the platen, re-press failed area for 5 extra sec.
Problem 09
Dye migration on polyester
Colours from polyester garment bleeding into the white underbase.
Fix — Polyester sublimation dyes activate above 130 °C — they migrate. Use poly-blocker spray, drop temp to 125–130 °C, longer press time (12 sec) to compensate.
Problem 10
Print washes off completely
Whole print lifts and washes away first time.
Fix — Press temp was too low, pressure insufficient, or you skipped post-press. Re-test with temp 10 °C higher, confirm firm pressure (fiver test), always post-press 5–8 sec, and hot peel within 5 sec of opening.

FREQUENTLY ASKED
Every question, answered.
If you're wondering, 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 process where your design is printed onto special PET film with a white ink underbase, then heat-pressed onto fabric. Unlike sublimation, it works on any fabric colour. Unlike vinyl, you get full-colour photo-realistic designs. Unlike screen printing, there's no setup cost — order one or a thousand.
DTF vs 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.
vs Screen printing: Screen 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.
What heat press do I need?
Any flat-bed heat press capable of reaching 160 °C with firm, even pressure. Skip household irons — they can't deliver even pressure and most don't hold temperature accurately enough.
Budget: Vevor, Hix. Professional: Stahls Hotronix Auto-Open, Adkins, Galaxy. For caps you'll need a curved cap press.
Can I use an iron instead?
Technically yes, but 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 post-press) 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. Suitable for sportswear, leggings, t-shirts, and anything else that moves with the body. Avoid extreme stretch (over 50% elongation) like dance leotards where vinyl might be better.
Do DTF prints feel rubbery?
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. Noticeable but not uncomfortable.
Cheapest way to order DTF transfers?
Buy in meterage rather than individual A3/A4 sheets. Our 56×500 cm gang sheet gives the lowest price per cm². Use the builder's Auto Fill to pack the sheet tight with multiple designs.
Can I order one-off custom prints?
Yes — 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 delivery?
Yes. All orders placed before 3 PM UK time ship the same working day. Royal Mail Tracked 24 usually delivers next day. Royal Mail Special Delivery by 1 PM is guaranteed next working day before 1 PM.
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 right-reading — exactly as you want it on the finished garment. Our printer mirrors it automatically when 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 the 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.
If you upload a poor-quality file and it prints exactly as supplied, we can't refund — but our resolution check warns you before ordering, and our team fixes files free before printing.
Do you ship internationally?
Currently UK only via standard tracked shipping. For Republic of Ireland, EU, and international wholesale, email info@doitdtf.com.
Can DTF be applied to caps and hats?
Yes, but you'll need a curved cap press. 155 °C, 12 sec, firm pressure. The cap structure prevents using a flat heat press effectively.
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: poly-blocker spray, press at the lower end (130 °C / 10 sec), or use sublimation-blocker DTF film.
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. Not on our menu yet but on the roadmap.
How do I store DTF transfers before pressing?
Flat, in original packaging, away from direct sunlight, in a cool dry place (under 25 °C, under 60% humidity). Stored correctly, transfers last 12 months with no quality loss.
Does on-screen colour match printed colour?
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 help with poor-quality artwork?
Yes. Upload anything to the builder — our resolution check tells you instantly if it's print-ready. For files needing 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.
