Paper Abstract

A unique, proprietary, holographic printing technology has been demonstrated using DuPont OmniDexTM Holographic Recording Films which can incorporate multicolor, image individualization and anticounterfeiting functions into volume holograms. Starting with a monocolor volume hologram, we describe a process using simple existing photopatterning technologies to introduce imagewise selective colors into the monochrome hologram. In this process a latent image is recorded in our OmniDexTM Color Tuning Film. This latent image is transferred to a prerecorded hologram by lamination and developed by heating. Bright, multicolor holographic images were achieved with high resolution. The process flexibility and applications of this technology to graphic arts holography and security printing will be discussed.
