Features & Benefits
Optimized for Printing Performance
| Aspect | Benefit for Customer |
|---|---|
| Surface Cleanliness | Low oil content and minimal surface defects |
| Flatness | Stable registration, reduced misprint risk |
| Coating Uniformity | Consistent color, gloss, and ink laydown |
| Ink Adhesion | Reliable bonding for offset, UV, and solvent inks |
| Color Consistency | Tight ΔE control for repeat orders |
The controlled roughness and chemical pretreatment promote strong adhesion between the coating and subsequent printing inks. This leads to fewer rejects, sharper images, and stable color management across batches.
Formability & Process Flexibility
| Process Type | Performance Description |
|---|---|
| Bending | Good for right angles and moderate radii |
| Stamping | Suitable for shallow to moderate draws |
| Embossing | Retains printed pattern and coating integrity |
| Die‑cutting | Clean cuts with low burrs, depending on tooling |
