Introduction
When it comes to industrial inkjet coding, especially on challenging substrates or high-security products, UV ink and pigmented ink are two standout solutions. While both offer high performance, they are fundamentally different in appearance, usage, and function.
In this article, we compare UV and pigment inks across performance criteria like visibility, adhesion, drying time, and traceability — helping you choose the right ink for your specific industrial application.
1. What Is UV Ink?
UV ink is typically invisible under normal light and only becomes visible under UV (black) light. It is used for security coding, traceability, and anti-counterfeiting. In industrial CIJ printers, UV ink is often MEK or ethanol-based, with UV-fluorescent dye additives.
2. What Is Pigment Ink?
Pigmented ink contains solid particles (like titanium dioxide or carbon black) suspended in solvent. Unlike dye-based ink, pigments don’t dissolve but stay on the substrate surface, delivering high-opacity and high-contrast printing, ideal for dark materials or harsh environments.
3. Feature Comparison: UV Ink vs Pigment Ink
| Feature | UV Ink | Pigment Ink |
|---|---|---|
| Visibility | Invisible to the eye (visible under UV light) | Highly visible (white, yellow on dark substrates) |
| Use Case | Security marking, covert traceability | Cable marking, automotive, food-grade foil |
| Adhesion | Good on plastics, paper, coated substrates | Excellent on plastic, rubber, foil, cable |
| Drying Time | Fast (1–2 seconds, depending on solvent) | Moderate (2–5 seconds), may need agitation |
| Security | High — covert code only seen under UV | Low — visible by default |
| Maintenance | Moderate — similar to dye ink | High — requires ink circulation or shaking |
4. Recommended Applications for UV Ink
- Pharmaceutical anti-counterfeiting codes
- Luxury cosmetics traceability
- Lottery tickets or promotional packaging
- Brand protection in high-value electronics
5. Recommended Applications for Pigment Ink
- Wire and cable marking (white/yellow on black)
- Food-grade flexible packaging with dark backgrounds
- Automotive rubber hoses and seals
- Carton or plastic coding in dusty/hot environments
6. Cheef Ink Solutions
| Cheef Code | Ink Type | Key Benefit | Application |
|---|---|---|---|
| C-V393UV | UV Ink | Invisible code under normal light | Pharma, cosmetics, secure packaging |
| C-W485WHITE | Pigmented (White) | High contrast on dark cable/plastic | Electronics, cable, auto parts |
| C-Y490YELLOW | Pigmented (Yellow) | Visible color code on black packaging | Wire, tubing, hoses |
7. Storage and Maintenance Tips
UV Ink:
- Store in dark, dry area (sensitive to light)
- Shake before use if instructed
Pigmented Ink:
- Agitate regularly or use circulating printer system
- Flush nozzles frequently to avoid settling and clogging
Conclusion
UV ink is the ideal choice for covert printing and brand security, while pigment ink provides bold, long-lasting marks on dark or non-porous surfaces. Each has a clear role in industrial coding. At ChinaCIJInk.com, we offer a full range of UV and pigment inks, tested for compatibility, stability, and performance in the toughest conditions.
