Question 4

Processing

Accepted Answer

Die-cutting:
Sharp knives, minimal web tension, and the use of double-sided siliconized release liner are recommended,
to prevent the effects of possible adhesive bleed.
Printing:
The best results are achieved with screen printing. A color qualification test before series production is recommended.The special surface coating is very well suited for thermal transfer overprinting. The optical appearance and durability of the overprinting depend on the ribbon used.
