Abstract: Processes and systems are described that can produce images including both three dimensional holographic images and two dimensional variable data, which can provide personalized security features in a document. A photosensitive film can be pressed against a first reflective optical device. A laser beam can be directed through a selected first area of the photosensitive film onto the first reflective optical device to produce a three dimensional holographic image in the photosensitive film. A previously masked second area of the photosensitive film can be pressed against a second reflective optical device. The laser beam can project an image constructed by a spatial light modulator and can be directed through the second area of the photosensitive film onto the second reflective optical device to produce a two dimensional image in the second area. During the process, the web tension of the photosensitive film is controlled.
