UVIFLEX INVISIBLE BLUE: Invisible UV Ink for Coding and Security
UVIFLEX INVISIBLE BLUE is a high-technology flexographic ink that remains completely invisible under normal lighting but is highly reactive to ultraviolet light. It is specifically formulated for advanced coding, traceability, and anti-counterfeiting applications on labels and packaging. Its formulation allows for instant UV curing, ensuring exceptional adhesion and stability across a wide range of packaging substrates. This makes it the ideal solution for hidden markings and internal quality controls without compromising the aesthetic integrity of the product design.
Machine Operational Advantages
- Total Invisibility and Preserved Aesthetics: The print remains entirely undetectable to the naked eye, ensuring the original label or packaging design is completely unaffected.
- High-Intensity Response: Emits an intense fluorescent blue glow under UV inspection lamps (365–395 nm range), facilitating rapid detection in automated vision systems.
- Instant Curing and Productivity: Its reactive technology enables immediate curing under UV systems (conventional or LED), maximizing production line speeds without blocking or offsetting issues.
- Robust Adhesion and Resistance: Excellent anchorage on coated and uncoated paper, cardboard, and corona-treated plastic films (PVC, PET, PP), providing high durability against handling and moisture.
Technical Specifications
| System Base | UV Curing (Acrylated oligomers and monomers with photoinitiators) |
|---|---|
| Chromatic Response | Invisible (visible light) / Intense fluorescent blue (UV light 365–395 nm) |
| Compatible Substrates | Paper, cardboard, and corona-treated plastic films (PVC, PET, PP) |
| Printing Systems | UV Flexography (standard units) and UV coaters |
| Operational Viscosity | Adjusted for flexographic transfer (dependent on anilox volume) |
Logistics, Applications, and Handling
- Key Applications: Ideal for hidden coding, anti-counterfeiting systems in premium packaging, logistical traceability control, and discreet promotional markings.
- Setup and Profiling: Select the appropriate anilox cell volume (BCM) to guarantee uniform coverage. Adjust the UV energy dose strictly to prevent residual post-cure tack.
- Storage: Keep in opaque, tightly closed containers. Store in cool, dry areas shielded from direct sunlight, UV radiation, and heat sources to prevent premature polymerization.
- Industrial Safety: Handle strictly using appropriate Personal Protective Equipment (PPE), avoiding prolonged skin contact. Consult the Safety Data Sheet (SDS) for comprehensive handling protocols.
