Confirm or weaken each cause before changing the next variable.
1
Time or temperature exceeds product tolerance
Evidence that supports it
- Paper browning, odor, shine, shrinkage, or deformation appears.
Evidence against it
- The defect is a clean untransferred area with no heat damage.
Safe next actions
- Stop and confirm the exact product instruction.
- Verify platen temperature before another test.
Stop condition: Stop immediately for smoke, melting, or an unfamiliar strong odor; ventilate and follow material safety documentation.
2
High pressure or platen edge is polishing heat-sensitive fabric
Evidence that supports it
- A shiny rectangle matches the platen or transfer edge.
Evidence against it
- Discoloration is unrelated to press geometry.
Safe next actions
- Use only the pressure the product requires.
- Test approved padding or paper-edge strategies on a spare blank.
