MYK has introduced a blue continuous inkjet (CIJ) ink developed for wire and cable marking. The formulation balances adhesion, color depth, and pigment load — three properties that tend to work against each other in CIJ inks.

Rub resistance is where this ink stands out. In fingertip rub tests, printed characters stayed sharp after multiple passes with finger pressure. That matters in cable production, where surfaces are handled constantly during manufacturing, coiling, and installation.

On common cable jacket colors, the blue code is easy to see. Yellow, orange, and light blue jackets give strong contrast right away. On purple and red, the mark reads as a dark code — still clearly legible, just through a different contrast mechanism. Edge definition held up across all tested colors, with characters staying readable.

Since it is a light-pigment ink, it runs on existing black-ink CIJ machines. Switching between black and blue coding does not require equipment changes. The light pigment also keeps ink circulation stable and jetting consistent in continuous systems.

For cable makers who need high-contrast, rub-resistant coding on light-to-medium colored jackets, this ink covers product traceability, batch coding, and general marking. It should also cut down on rework from prints that come out unreadable.
