Other Security Features

Paper labels can incorporate a variety of anti-counterfeiting features.

Features like holograms, thermochromic ink, hydrochromic ink, infrared ink, etc., can enhance the security of paper labels.

Hologram: Combining holograms with paper labels through hot stamping, lamination, or embedding processes enhances the label's security and visual appeal.

Integrating customized holograms with paper labels enhances security, preventing counterfeiting. The unique features of custom holograms, including the possibility of embedding them as security threads during paper production, contribute to heightened anti-counterfeiting measures.

Hydrochromic Ink: Water-changing ink, also known as water-sensitive ink, comes in solvent-based or water-based screen printing forms, categorized as irreversible or reversible.

Irreversible hydrochromic ink, often blue or black, shifts from color to clear when wet, maintaining the clear state upon drying. On the other hand, reversible hydrochromic ink, typically milky white, becomes colorless when exposed to water and reverts to its original color after water evaporation.

Thermochromic ink: Thermochromic ink, also known as heat-sensitive ink, changes color with variations in temperature. It is typically categorized as reversible or irreversible.

Reversible thermochromic inks alter their color temporarily with heat and return to the original state after cooling, while irreversible inks maintain the color change even after returning to the original temperature.

Infrared ink: Infrared ink, often abbreviated as IR ink, encompasses three main types: infrared transparent ink, infrared excitation ink, and infrared absorption ink, each producing distinct effects upon exposure to infrared rays.

Infrared transparent ink appears pure black under normal light but turns colorless and transparent when exposed to infrared light, offering symmetrical anti-counterfeiting potential. Infrared excitation ink, initially colorless, emits visible light when excited by 980nm infrared light, displaying colors like red, blue, green, or yellow. Infrared absorbing ink, usually colorless or light-colored, reveals black marks when viewed through an infrared filter at specific wavelengths like 650nm, 775nm, 810nm, or 880nm.
