Cold Foil Nip Pressure and Roller Hardness / 冷烫压合压力和胶辊硬度怎么影响转移
## Quick Answer Cold Foil Nip Pressure and Roller Hardness should be specified by process route, substrate, adhesive or UV varnish compatibility, artwork detail, and finished-package durability. For machine operators, the safest buying path is to test the foil on laminating nip rollers and foil webs, using the actual machine route for roll-to-roll and sheet cold foil transfer. The main purchasing risk is contact uniformity, pressure marks, and transfer density. Do not approve a cold foil roll by color alone; approve it by transfer completeness, edge clarity, gloss, adhesion, rub resistance,…
