What is Hard UV Ink?
Hard UV ink (also called rigid UV ink) is a 100% solids UV-curable inkjet ink formulated to cure into an extremely hard, durable, and scratch-resistant film under ultraviolet light. It is specifically engineered for use on uv flatbed inkjet printer systems, delivering exceptional bonding and stability on rigid, non-flexible substrates.
Classifications & Industry Standards
1. By Compatibility
- Universal hard UV ink for standard flatbed printers
- Premium hard UV ink for industrial-grade uv flatbed inkjet printer models
2. By Curing Type
- LED hard UV ink (low energy, instant cure)
- Mercury lamp hard UV ink (high intensity, industrial production)
3. Global Certifications
- RoHS & REACH compliant (low heavy metals)
- Oeko-Tex Standard 100 (safe for direct contact)
- ISO 105-Z01 (color fastness & abrasion resistance)
