The custom artwork is then sent to our holography laboratory where the holographer creates and combines the necessary photographic and holographic elements to produce a "master" hologram on special photosensitive emulsions.
As with all holograms, the multidimensional image is recorded as a unique "interference pattern" which is created using laser light and precision optical techniques.
