Comprehensive Guide & Technical Breakdown
While both utilize UV-curable polymer varnish, their application scope and design intent differ:
### 1. Flood UV Coating (Full Coverage)
- Application: Applied across 100% of the sheet surface.
- Visuals: Creates a uniform, brilliant high-gloss or deep-matte shell over the entire box.
- Protection: High barrier against moisture, scuffing, and fingerprints.
- Cost: Lower tooling cost than spot UV because no selective plate or silkscreen mesh is required.
- Application: Applied only to specific coordinates (logos, illustrations, typography, or water droplet patterns).
- Visuals: Creates a dramatic sensory contrast between high-gloss coated elements and the surrounding matte or soft-touch background.
- Best for: Luxury branding, pattern textures, and high-end e-commerce unboxing lids.
### 2. Spot UV Coating (Selective Highlights)
