Unifying fast computer-generated hologram calculation and prepress for new and existing production techniques

Abstract

Directed by successfully manufacturing the computer-generated hologram (CGH) using the computer-to-film (CtF) process, we present, to the best of our knowledge, a new method for low-cost and fast hologram manufacturing. This new method allows for advances in the CtF process and manufacturing using new techniques in hologram production. These techniques include computer-to-plate, offset printing, and surface engraving utilizing the same CGH calculations and prepress. With an advantage in cost and the possibility to be mass manufactured, the aforementioned techniques combined with the presented method have a solid foundation to be implemented as security elements.
