SJH magnetic chameleon ink application on glass test: flowing color-shift effect following magnetic field lines with strong 3D sense - for glass, packaging and high-end anti-counterfeiting.
A full written description of the demonstration, so the content is readable without playing the video.
This video demonstrates SJH magnetic chameleon ink applied to glass: the ink layer shows a flowing colour shift with viewing angle and magnetic field lines, with a strong three-dimensional effect - for premium packaging and glassware security.
The video first shows the effect of magnetic chameleon ink printed on glass. Glass is a non-absorbent substrate with far higher adhesion demands than paper, so this application needs a purpose-formulated ink and process; paper-grade colour-shift ink applied directly to glass often bonds poorly and flakes.
As the camera changes viewing angle, the ink colour shifts in a flowing manner rather than simply jumping from one colour to another. Magnetic colour-shift pigments are platelet-shaped and are aligned in a magnetic field during printing; as the viewing angle changes the reflection path changes, producing the angle-dependent optical effect.
The video further shows the three-dimensional pattern created by field-aligned pigments. Designing the magnet pattern controls pigment orientation, effectively engraving a 3D image into the ink layer - an effect that requires dedicated magnetic equipment and is extremely hard to replicate.
| Principle | Platelet magnetic pigments aligned in a field produce a flowing angle-dependent colour shift |
|---|---|
| Substrate | Glass is non-absorbent and needs a dedicated formula for adhesion - proof first |
| Barrier | Dimensional alignment needs dedicated magnetic equipment and process control, very hard to copy |
| Typical use | Premium packaging, wine and cosmetics glass bottles, luxury brand marks |
The value of magnetic chameleon ink is the combination of dynamic colour shift and dimensional alignment: a static printed pattern is easy to copy, while flowing angle-dependent colour and field-dependent 3D structures are extremely hard. It is a preferred security option for non-absorbent substrates such as glass and metal, but adhesion on those substrates must be validated by real proofing - request a printed proof on glass or the actual substrate before mass production.
