Start with the receiving surface
Check fabric composition, coatings, dye behavior and seams. A thick hooded garment and a flat cotton tee may receive different effective pressure even when the press display shows the same setting.
Change one variable at a time
Use small test pieces to adjust temperature, dwell time and pressure independently. If stones lift, first check contact and carrier orientation before increasing heat; excess heat can damage the textile or adhesive.
Specify the complete process
The production instruction should include pre-press, protective layer, press cycle, peel condition and any finishing press. Check the result after cooling and after the intended care test.
Field exercise
Build a setting record another operator can reproduce
Imagine the same transfer tested on a smooth tee and a hoodie with a raised seam near the design. The display setting may be identical, yet the contact at the stones differs. Start with the supplier's procedure, note the press model and protective layer, and test the garment on a flat area. If the hoodie fails, examine platen contact and seam clearance before changing temperature. Any revised setting needs its own labeled sample and care check.
Evidence to retain
- 01Write down garment composition, press model, platen arrangement and sample position.
- 02Log temperature, dwell, pressure method, peel condition and any second press as one complete recipe.
- 03Keep the applied sample and the after-care result together with the recipe.
