Magneto-optical ink designed for screen printing; magnetic fields trigger the formation of beam-like patterns. It offers strong adhesion and multi-layered anti-counterfeiting features that make replication difficult.

This specialized magnetic color-changing ink for screen printing incorporates magnetically responsive micro-particles; a unique beam-like pattern instantly emerges when a magnet approaches and reverts automatically when the magnetic field is removed, offering a distinctive and intuitive visual effect. The ink features uniform pigment dispersion, smooth screen-printing flow, and strong adhesion, while demonstrating excellent resistance to abrasion and solvents as well as high colorfastness. Impossible to replicate via standard photocopiers or scanners, it provides a high level of security and is suitable for anti-counterfeiting applications on packaging, certificates, and creative merchandise. Safe and eco-friendly, it offers rapid color-changing response and consistent performance in mass production, enabling the creation of differentiated, high-end anti-counterfeiting marks.
