DNP has developed a new technology for Virtuagram, with twice the luminance over the conventional products, ideal for anti-counterfeiting of passports and other ID documents requiring quick and simple authentication. The Virtuagram is a hologram made by using 3-dimensional computer graphics (CG). In conventional Hologram technology, where the holograms are place onto such document as passport tend to reduce their luminance due to roughness of the paper surface. But DNP’s new technology for Virtuagram modifies the relief patterns on the hologram master helping it to increase its reflectance by combining the latest CG technologies with high-definition electron beam lithography, increasing the luminance of the hologram by two fold in comparison to hologram manufactured using conventional CG technologies. High-resolution 3D images provide a first confirmation step for authenticity, followed by other authenticity measures that include printing a layer of materials with specific optical properties over hologram, allowing user to view the material with special viewer.
