Hologravure process: Hologravure is one application of the science of interferometry (as utilized in the graphic arts' industry), giving optic images the effect of relief, viewed either through transparency or by reflection.

Our three-dimensional technologies are unique in the world. There have been progressive and exponential generational developments beginning with the lined backgrounds and multiplicity of planes in space.

The second generation introduced half-tinted metal effects and embossing, as well as the ability to work directly on the design to achieve the desired effect.

The third and most recent generation can produce plain backgrounds, nonvisible interferences, flat geometrical objects as well as volume or information in space. Unique new products arising from our technologies of optical impression (speckle, diamond effects, etc.), will give traditional 2D creations another dimension and another aspect in space with the harmonious mixing of these two dimensions on the same support.
