Customers rarely praise a neck label, but they certainly notice one that scratches. That is why so many T-shirts, running tops, leggings and baby bodysuits now carry a printed logo and size where the sewn label used to be. These tagless labels are heat transfers, and getting them right depends as much on the press settings as on the print itself.
We manufacture heat transfer labels with OEKO-TEX certified inks and supply each order with application guidance for the customer’s fabric. This guide explains the technology, the settings and the design choices.
How a transfer is built
A transfer is printed in reverse onto a release film or paper: first the ink layers, then a heat-activated adhesive. In the press, heat and pressure melt the adhesive into the fabric surface. The carrier is peeled away and the design remains as part of the textile, with no tape and no edge.
Choosing the transfer type
Screen-printed
Each colour is screened onto the carrier, followed by adhesive. Plastisol gives a smooth, slightly raised print; soft-hand and silicone-based inks produce a very thin, stretchy film. Screen-printed transfers are the choice for longer runs in one to four spot colours, with crisp edges and Pantone-matched colour.
DTF (direct to film)
The design is printed digitally with pigment inks, coated with adhesive powder and cured. With no screens involved, DTF handles full-colour logos, gradients and photographic detail, and it suits size runs where each print differs.
Low-temperature with blocker
Dyed and sublimated polyester can release dye when heated, turning a white print pink or grey. Low-temperature systems with a grey or black blocker layer stop that migration. Tell us if your garments are dyed polyester so we specify the right system.
| Type | Colours | Feel | Good for |
|---|---|---|---|
| Screen-printed plastisol | 1–4 spot colours | Smooth, slightly raised | Cotton tees, sweatshirts, merchandise |
| Screen-printed soft-hand or silicone | 1–3 spot colours | Very thin, stretchy | Sportswear, underwear, babywear |
| DTF | Full colour and gradients | Thin, flexible | Multicolour logos, short size runs |
| Low-temperature with blocker | 1–3 spot colours | Thin | Dyed and sublimated polyester |
Press settings that matter
A heat press with even temperature and pressure is essential; a small platen or interchangeable neck platen makes collar areas easier. A household iron is not suitable. The parameter sheet for your specific transfer always takes priority, but typical ranges are:
| Setting | Typical range | Practical note |
|---|---|---|
| Temperature, cotton and blends | about 150–170 °C | Verify with a surface thermometer |
| Temperature, polyester and nylon | about 125–150 °C | Low-temperature systems for sensitive fabrics |
| Dwell time | about 8–15 seconds | Shorter on light synthetics, longer on heavy cotton |
| Pressure | Medium to firm, even | Use a pad so collar seams do not lift the platen |
| Peel | Hot, warm or cold | Defined by the carrier |
| Post-press | Optional, 3–5 seconds | With a cover sheet, improves durability and matt finish |
Hot-peel carriers come off as soon as the press opens, ideal for fast lines. Warm-peel waits a few seconds. Cold-peel stays on until fully cool and gives the cleanest edges on fine detail; peeling it early lifts the print. Make sure everyone on the line knows which type they are using.
A routine for the press operator
- Pre-press the garment for 2–3 seconds to drive out moisture and creases.
- Centre the transfer between the shoulder seams, usually 2–3 cm below the neck seam.
- Press at the specified temperature, time and pressure, keeping the collar seam off the platen.
- Peel according to the carrier type.
- Post-press with a cover sheet if recommended.
- Leave the garment for about 24 hours before the first wash.
Always test on your production fabric and wash the sample several times at your care-label temperature.
Fabrics and durability
Transfers bond to cotton, polyester, cotton-polyester and viscose blends and nylon, including high-elastane fabrics. Soft-hand inks stretch and recover with the fabric, which is why they dominate in leggings, swimwear and underwear. Water-repellent coatings, very open mesh, high-pile fleece and heat-sensitive fabrics need special adhesives or a sewn label.
Applied correctly, a transfer is designed to last the life of the garment under normal home washing. When problems occur, the cause is almost always application: too little heat, a press reading higher than its real temperature or a seam holding the platen off the print. For industrial laundering, ask for a system specified for those conditions.
Design and sizes
Single-colour prints in white, black or grey are most popular for necks, because they stay discreet through thin fabric. Keep lines at roughly 0.3–0.5 mm or thicker and avoid very fine serifs, which can fill in.
Adult neck prints typically range from about 30×30 mm to 50×50 mm. Formats up to around 80×60 mm hold more text, and slim 60×25 mm shapes suit narrow kidswear necks.
What to include in the print
- Logo or brand name.
- Size, clearly readable on a hanger or in a folded stack.
- Country of origin, if you use one.
- Core care symbols in the standard order: washing, bleaching, drying, ironing, professional care.
- Fibre composition, if it fits legibly in every required language.
Because Regulation (EU) No 1007/2011 requires durable composition text in the language of each sales country, brands selling in several markets often keep the full text on a small side-seam care label and print only brand, size and symbols at the neck.
Send us your logo, fabric, colours, sizes and press details. We prepare a print-ready layout and digital proof, typically within 24–48 hours, and test transfers before production. See heat transfer labels or contact [email protected], WhatsApp/Viber +359 876 766 050.
Can I apply heat transfer labels with a household iron?
Not reliably. An iron cannot deliver the even temperature and pressure a transfer needs; use a heat press, ideally with a small neck platen.
Why did my white neck print turn pink?
That is dye migration from dyed or sublimated polyester. A low-temperature transfer with a blocker layer prevents it.
Which transfer type is best for a full-colour logo?
DTF, because it prints digitally and reproduces gradients and fine colour detail without separate screens.
How long should I wait before washing a pressed garment?
About 24 hours, so the adhesive bond can settle fully.
