1
Excess time, temperature, or pressure
Evidence that supports it
- Paper browning, coating softness, or surface imprint accompanies sticking.
Evidence against it
- The product instruction explicitly requires a cold peel and the item is still hot.
Safe next actions
- Confirm hot/warm/cold removal instructions before pulling.
- Return to the documented setting and change one variable at a time.
2
Paper or coating combination is incompatible
Evidence that supports it
- Sticking repeats with one paper/product combination.
Evidence against it
- A control with the same materials releases correctly.
Safe next actions
- Use the paper specified by the ink/blank workflow.
- Test a supplier-approved alternative on a spare blank.
