Two shirts with the same colour can behave differently under a press. Fabric composition, surface texture, seams and finishes all deserve attention before the transfer is applied. Choosing the garment is part of print preparation, not a decision to leave until the artwork is ready.
Read the label and the transfer instructions
Start with the garment composition and care label. Then check whether the transfer supplier supports that material. A fabric name alone does not guarantee the same result across every garment. Finishes and construction can change how a particular item behaves.
Check the print area
Lay the garment on the platen before pressing. Look for seams, pockets, zips and thick panels near the design. These can affect contact with the press. Decide whether the intended placement gives the transfer a sufficiently flat surface and follows the equipment instructions.
Test the garment you will actually deliver
Use the same garment type and colour planned for the order. Inspect the sample for marks, unwanted colour changes and lifting edges. Carry out the recommended care test after the specified waiting period. Keep the approved sample for comparison.
A fabric compatibility checklist
| Garment feature | Question before pressing |
|---|---|
| Composition | Does the transfer supplier support this material? |
| Dark or dyed fabric | Does the sample show unwanted colour entering the printed area? |
| Stretch fabric | Does the intended placement stretch more than the approved transfer can accommodate? |
| Surface finish | Has this exact garment been tested, rather than a visually similar item? |
| Construction | Can seams and fasteners remain clear of the pressing area? |
Why polyester needs a sample
Some dyed polyester garments can show colour migration into a print. The risk depends on the specific fabric, dye and transfer system. A polyester percentage alone does not establish compatibility. If an approved transfer calls for a particular low-temperature or blocking system, use its complete instructions instead of improvising a lower temperature for a different product.
A practical approval sequence
- Select one garment from the actual intended range.
- Inspect the unprinted surface and record existing marks.
- Apply the transfer within both the garment and transfer requirements.
- Inspect the print after application and after the relevant settling period.
- Perform the specified care test and compare with the initial appearance.
Keep photographs under comparable lighting. Do not approve a large run on the basis of a phone photograph alone if the issue involves feel, stretch or subtle colour changes.
Example: the same logo on shirts and hoodies
A smooth shirt and a thick hoodie are not identical jobs. A hoodie pocket or seam may obstruct platen contact, while the intended logo placement may require a different loading method. Approve each garment separately even when the artwork and transfer are unchanged.
Frequently asked questions
Can DTF work on cotton and polyester?
Compatible DTF products exist for common garment materials. Suitability still depends on the specific transfer and garment, so check the product guidance.
Can I print onto waterproof fabric?
Do not assume compatibility. Coatings and heat limits require explicit supplier guidance and a test on the exact item.
Should I change settings for a thicker garment?
Review loading, contact and the product instructions. Thickness alone is not a reason to invent new pressing values.
A small test is more informative than guessing from a fabric description. Record the garment reference alongside the transfer details so the next order can repeat the combination.
