Practical notes on applying heat transfer labels to garments

Before ordering a label for a garment, identify the label type and how it will be applied. For a logo or information label heat-applied to fabric, material selection, trials on the production fabric and control of the press process provide the basis for sample approval.

1. Identify the label type before ordering

“Thermal label” can refer to a label printed by a thermal printer or, in some enquiries, a graphic heat-applied to fabric. A thermal printer may use direct thermal media or transfer ink from a ribbon; these terms describe label-printing methods. A garment heat transfer label carries artwork that is transferred and bonded to the fabric through a suitable application process.

This guide focuses on applying logos and information labels to garments. Include a reference sample or application photograph in your enquiry so both teams can identify the correct construction.

2. Test on the actual production fabric

Provide the fabric sample with its composition, colour, stretch and any coating or finish information available. Review fabric appearance after pressing, label adhesion, press marks and colour changes. For stretch garments, assess the sample within the intended stretch range at the application site.

3. Prepare the artwork and label information

Send editable original artwork with finished dimensions and colour requirements.
Confirm logo content, lettering, size information and orientation before sampling.
Check fine details at actual size; a photograph is an appearance reference.
If the design includes a barcode or QR code, test readability on the actual sample before approval.

4. Use the settings for the selected material

Confirm temperature, time, pressure, carrier removal and any additional pressing step against the instructions for the chosen label. A single recipe does not cover every fabric and label material. When equipment or the application position changes, review a sample using the actual setup.

Keep the garment stable and review raised seams or uneven surfaces that affect contact and pressure. If the design must cross these areas, discuss the support arrangement and develop a separate application trial before production.

5. Remove the carrier as instructed

Some materials require removal while hot, after cooling or under other specified conditions. Follow the instructions for the exact label. If details shift or edges lift, retain the affected sample and review the material, fabric and process before continuing.

6. Agree on washing tests before bulk production

Confirm the washing and drying methods, cycle count and acceptance criteria required for the finished product. Test after the conditioning period specified by the material instructions. Check adhesion, edge lifting, broken details, colour change and distortion on both the label and fabric.

Record the label code, fabric, equipment and application settings for the approved sample. A result supports the tested combination; review it when the fabric, label material or press conditions change.

7. Control storage and production handling

Store labels according to their material instructions in suitable packaging; keep surfaces clean and protect the carrier from creasing.
Separate codes, sizes and colours to reduce mix-ups during issue to production.
Check a first sample at the start of a shift and after material or equipment adjustments.
Keep the approved sample and working instructions for comparison when defects occur.
