Optical Variable Ink (Color‑Shifting Ink) Introduction

Optical Variable Ink (OVI) is a core anti‑counterfeit material widely adopted in global security printing. Its most prominent feature is the angle‑dependent color‑shifting effect: under normal observation, it shows one color, while tilting the surface will change to another obvious color.

This special visual effect relies on advanced optical pigment technology, which is difficult to imitate by conventional printing, scanning, copying and digital printing technologies. Our OVI features bright color contrast, stable color shifting performance, strong weather resistance, good adhesion, fast drying speed and compatibility with screen printing, gravure printing and offset printing processes.

It is mainly applied for banknotes, national official certificates, passports, ID cards, tax stamps, lottery tickets, high‑end luxury packaging, pharmaceutical anti‑fake labels, brand security stickers and other high‑security fields, providing reliable visual anti‑counterfeit protection for governments, financial institutions and brand enterprises.
