Question
How is holographic foil different from metallic foil?
Answer
Both use the same heat-stamping process, but the finish is different. Metallic foil is a single reflective color, while holographic foil splits light into a shifting rainbow.
| Metallic foil | Holographic foil | |
|---|---|---|
| Color | One tone (gold, silver, copper, rose gold) | Full-spectrum, shifting |
| Effect | Steady reflective shine | Rainbow that moves with angle |
| Pattern | Solid | Diffraction pattern |
