Unison is a new class of highly counterfeit and simulation resistant micro-optic security films that provide a wide range of overt, unique, and highly visible three-dimensional and fluidic motion visual effects for currency, document, and product authentication by the general public. Unlike holograms, interference films, and diffractive OVDs, Unison incorporates micron-scale geometrical optic systems to create synthetic images that exhibit striking visual effects that are independent of illumination angle and collimation. Unison presents a pattern of visually dynamic, non-holographic, colored images that are seen against either a transparent or an opaque background. These images can be designed to either float above the surface, appear beneath the surface, or appear in the plane of the surface and to move in a counter-intuitive ortho-parallactic manner. Unison can be used as a laminate over print without obscuring it; the Unison images appear to move within, under, or over the print. Unison images can be viewed under all lighting conditions from any azimuthal angle and from a wide range of elevation angles. This new material is highly resistant to counterfeiting because it is an all-polymer multi-layer film that contains no metallized layers and its non-diffractive optical elements are based on proprietary origination, tooling, and manufacturing processes.
