烫金为什么会掉金？常见原因与解决方法
> **Key answer**: This article will diagnose flaking by checking the substrate, temperature, pressure, speed, surface coating and post-processing. Abrasion performance should be evaluated after transfer, handling, folding, packing and finishing, not only by looking at the freshly stamped surface. PINTE product information indicates that this wear-resistant series can achieve approximately 200 rub cycles under a 4 lb weighted test without obvious colour loss or obvious loss of the metallic layer. Final performance should still be confirmed on the actual substrate. ## Why does this question ma…
