| Step | Operation | Criterion |
|---|---|---|
| Step 1: Check Pressure | Press down on garment after plate engagement, feel if pressure is even | Edges noticeably looser than center → insufficient or uneven pressure, tighten pressure bar |
| Step 2: Confirm Peeling Method | Ask customer if they peel hot or cold | PU film must cool completely before peeling – hot peeling will cause edge lifting |
| Step 3: Check Washing Method | Ask about wash temperature and whether design was scrubbed | Hot water + aggressive scrubbing = even the best transfer won't hold up |
| Step 4: Try Different Film | If all above are ruled out, test with a different brand of adhesive film | No lifting with new film → original film poor quality, consider switching suppliers |
One-Sentence Summary: Insufficient pressure, hot peeling, or harsh washing – any one of these three will cause edge lifting.
Prevention: Include a "Care Instruction Card" with each order – hand wash in cold water, air dry inside out, do not scrub the printed area.
