Requirements for Inkjet Printer Ink in the Wire and Cable Industry

22 Sep,2025

The wire and cable industry has strict requirements for inkjet printer ink because products must maintain clear, durable markings under long-term use, bending, friction, sun exposure, and rain. The main requirements include:

Strong Adhesion

Ink must firmly attach to cable surfaces made of different materials such as PVC, PE, PP, and rubber
Should not peel off due to friction, bending, or handling
Must remain stable during subsequent processing like extrusion or winding that involve high temperatures or pressure

Weather and Environmental Resistance

UV resistance: Outdoor cable markings must resist UV radiation to prevent fading
Water, oil, and chemical resistance: Must withstand humid, oily, acidic, and alkaline environments
Wide temperature tolerance: Maintains performance typically from -20℃ to 80℃ or wider range

Quick Drying

Wire and cable production speeds can reach tens of meters per minute
Ink must dry instantly to prevent smudging after printing

Color and Contrast

Black or white inks are most common
Must provide high contrast with cable background for long-distance readability
Color stability is essential for consistent appearance over time

Environmental Protection and Safety

Must comply with RoHS, REACH, and other environmental standards
Should be free of heavy metals and toxic solvents
Some applications (food, medical, marine cables) require stricter non-toxic certifications

Compatibility with Inkjet Printers

Ink viscosity, conductivity (for piezoelectric printers), and drying speed must match equipment specifications
Different formulations required for continuous inkjet (CIJ) and drop-on-demand (DOD) technologies
