Introduction
Marking black cables, pipes, and tubes requires high-contrast ink — and white pigmented ink is the industry standard for this purpose. But due to its solid particle content, white ink comes with challenges like settling, clogging, and adhesion control.
This article provides a complete guide to successfully using white CIJ pigmented ink for cable and tube marking, including printer settings, maintenance tips, and ink handling best practices.
1. Why Use White Pigmented Ink for Cable and Tube?
Black substrates dominate in cable manufacturing, automotive tubing, and flexible hose applications. Standard dye-based inks are not visible on these surfaces.
White ink advantages:
- High contrast on dark plastics (PE, PVC, rubber)
- Durable markings even on curved and flexible surfaces
- Good resistance to smudging and outdoor exposure
2. Technical Properties of White Pigmented Ink
| Property | Typical Range | Impact |
|---|---|---|
| Viscosity | 3.2–3.6 cP | Ensures consistent flow with pigment |
| Conductivity | 1000–1800 µS/cm | Proper droplet charging for CIJ |
| Drying time | 2–4 sec | Requires airflow or solvent tuning on non-porous surfaces |
| Particle size | 0.3–0.6 µm | Smaller particles = lower clogging risk |
3. Substrate Compatibility
| Material | Ink Adhesion | Notes |
|---|---|---|
| PVC Cable Jacket | Excellent | Most common material in wire & cable |
| PE/PP Tubing | Moderate | May need pre-treatment or adhesion enhancer |
| Rubber hose | Good | Use low-flex formulations for stability |
4. Best Practices for White Ink Use
✔ Agitate Regularly
- Shake ink containers before loading
- Use printers with ink circulation (e.g., Domino A320i, Videojet 1710)
✔ Flush Often
- Flush printhead weekly to avoid dried pigment buildup
- Use Cheef C-V901 or pigment-compatible flush solvent
✔ Use Wider Nozzles
- Consider 70μm+ nozzles to prevent clogging
- Fine print possible with high-DPI adjustments
✔ Control Environment
- Maintain ink temperature (10–30°C)
- Avoid direct sunlight or heat on ink tanks
5. Recommended Cheef White Pigment Inks
| Ink Code | Solvent | Use Case | Features |
|---|---|---|---|
| C-W485WHITE | MEK | Black PVC wire, rubber hose | Strong opacity, fast drying, recirculation compatible |
| C-W486FOIL | Ethanol | Low-VOC cable coding | Lower odor, cleaner operation |
6. Print Quality Optimization Tips
- Adjust drop delay and phase to improve clarity on curved surfaces
- Use high-resolution fonts for small-diameter cables
- Print at lower speeds (under 150m/min) for best adhesion
7. Troubleshooting Common Issues
| Issue | Cause | Solution |
|---|---|---|
| Ink settles quickly | Ink not agitated | Shake container, enable printer recirculation |
| Nozzle clog | Dried pigment in printhead | Flush with solvent, clean nozzle tip |
| Faint or broken characters | Incorrect pressure or drop formation | Calibrate drop delay, check ink filters |
Conclusion
White pigmented inks are essential for high-visibility cable and tube marking, but they require proper system design and operator care. By following best practices — from ink agitation and flushing to print speed adjustment — you can ensure consistent, legible results.
