Ink that appears glittery and varies with angle is called?

• A. UV Ink
• B. Glitter Ink
• C. Holographic Ink
• D. Optically Variable Ink

Answer: (D)

Optically variable ink is designed to look different when you view it from different angles. The glittery, sparkling effect comes from tiny structures inside the ink that diffract or interfere with light. As you tilt the surface, those structures reveal different wavelengths, causing color shifts and a shimmering appearance. That angle-dependent change is what sets this ink apart from others that only sparkle (glitter ink) or glow under UV light, and it also encompasses holographic effects (which are a specific type of optically variable feature). In short, the glittery, angle-changing look is characteristic of optically variable ink.
