🕵️♂️ Unlocking the "Chameleon" of Anti-Counterfeiting: Why Do Your Security Labels Fade So Easily?
Have you ever experienced this? You purchase a premium product, and the security label on the packaging looks high-end at first. But after a few months in the warehouse, or with just a little friction, the colors look dull, or the ink simply scratches right off? 😱
Many people immediately assume it’s a "fake security label" or that inferior ink was used. As veterans in the brand protection industry, let us share an insider secret: Often, the ink isn't to blame—it's the underlying printing process that was chosen incorrectly!
Today, let’s talk about a game-changer in the security printing world: Flexographic Printing (Flexo).
If printing were like painting, the commonly used Offset Printing would be like using "watercolors". It delivers excellent detail, but the pigment layer is exceptionally thin.
Flexo Printing, on the other hand, is like applying "thick 3D impasto" or frosting on a cake! It applies a thick, rich, and saturated layer of ink onto the substrate. 🍰
Why does this "thickness" matter so much? It makes all the difference!
Remember the Optical Variable Ink (OVI), When you tilt a certificate or security card, the color of the printed pattern undergoes a distinct, visible shift (for instance, transitioning from red to green). This is because color-changing inks include optical thin films made of micro-particles, which reflect different colors depending on the wavelength of the light. The molecular structure of the pigment enables selective reflection of certain wavelengths, thus displaying different colors under various angles or lighting conditions.
So, the next time you're customizing premium security labels or certificates, be sure to ask your supplier: "Are you using Flexographic printing?" 😉
