Holographic Paper
The paper is placed in a device that generates heat and a vacuum. The metal is then heated until it evaporates and rises as a gas, most often aluminium. The gas hits the paper's surface and coats it with a thin, practically translucent film. The result of the effect is the scattering of the light by metalized coating when light hits the holographic paper. Kiran Holographics is one of the best producers of holographic metalized paper, and they are one of the best distributors of the same.
