DNP Lippmann Holographic
Dai Nippon Printing has developed a Lippmann hologram of various shapes which can be hot stamped onto plastic cards requiring high security and premium design, which includes ID cards as well as warranty cards. The hologram are manufactured by coating films with a special polymeric material and altering the density of the interior of this material to form interference patterns due to changes in refractive index.
