Troubleshooting Cold Lamination Problems
1) Bubbles / “silvering”
สาเหตุ: dust, uneven pressure, too high speed
แก้ไข: clean rollers/media, slow down, increase pressure slightly, squeegee from center outward.
2) Wrinkles or skew tracking
สาเหตุ: roll tension issues, misalignment
แก้ไข: reload rolls square, use side guides, reduce speed until tracking is stable.
3) Edge lifting / poor adhesion
สาเหตุ: contaminated surface (oil), insufficient pressure, low surface energy substrate
แก้ไข: clean substrate properly, apply firmer pressure, consider higher-tack laminate for difficult surfaces (film options vary by supplier).
