Holographic foil stamping is a high-security decorative process that applies light-diffracting foil patterns to packaging substrates using heat and pressure. It produces dynamic, color-shifting optical effects that vary with viewing angles, serving both aesthetic and anti-counterfeiting purposes.

Key Features

✔ Optical Security – Micro-engraved holograms deter duplication
✔ Visual Impact – Rainbow color shifts (e.g., gold-to-green transitions)
✔ Brand Protection – Custom holographic patterns for authentication
✔ Versatility – Works with hot stamping, cold foil, or digital methods

Technical Process

1. Holographic Foil Types

   • 2D/3D Holograms: Geometric patterns with depth illusion

   • Dot-Matrix: Micro-perforated security codes (≤0.1mm dots)

   • Kinetic Effects: Animated visuals when tilted

2. Tooling Requirements

   • Brass/Magnesium Dies: Precision-etched to match hologram relief

   • Silicon Counterforce: Even pressure distribution

3. Stamping Parameters

   • Temperature: 110–140°C (varies by foil brand)

   • Pressure: 25–40 kg/cm²

   • Speed: 1,000–3,000 impressions/hour

4. Substrate Compatibility

   • Best for: Coated paper, synthetic films, laminated boards

   • Avoid: Rough/uncoated surfaces (causes foil fragmentation)
