Record the substrate
Note fabric blend, knit or weave, surface treatment, color, and any printed or coated area near placement. Test on a panel from the actual blank when possible. Do not generalize a pass from one garment family to another.
Check heat-transfer label compatibility on the intended fabric, finish, stretch zone, placement, and care routine.
Buyer perspective
A label sample on a plain swatch proves little about a different finished garment. Fabric finish, stretch, dye, seams, and care can all change the applied result. The compatibility test should identify the exact garment combination being approved.

Sample protocol
The same transfer artwork can behave differently on two garments that look similar in a catalog. Use the actual blank, surface finish, and label location for a small application test. Keep an undecorated control beside the sample so changes to texture or color are easier to see.
Record fabric composition, finish, stretch direction, and the intended placement on this garment.
Inspect the transferred text and surrounding fabric once the sample has cooled.
Flex the placement and follow the garment's planned care routine, then compare with the control.
Treat a result on another fabric or finish as a clue, not approval for the garment being ordered.
What to decide
Note fabric blend, knit or weave, surface treatment, color, and any printed or coated area near placement. Test on a panel from the actual blank when possible. Do not generalize a pass from one garment family to another.
Inspect edge contact, alignment, legibility, surrounding press marks, and hand feel after the garment cools. For stretch areas, assess the mark both relaxed and under representative tension.
Use the care process planned for the sold garment, then examine the label again. Keep the tested application method and physical sample with the garment identifier. A changed fabric or finish requires a new check.

Compatibility is a property of the label-plus-garment process, not of a label in isolation. Reject a placement that cannot be pressed and inspected consistently.
