Abstract

An optical-effect device (300) comprising: a substrate (302) having a first surface (304) and a second surface (306); a plurality of structures (308) arranged on the first surface (304), each structure (308) having a first facet (310) and a second facet (314), the first facet (310) of each structure (308) being substantially parallel to the first surface (304) of the substrate (302), the second facet (314) of each structure (308) defining a slope with respect to the first surface (304), and the first facets (310)of the plurality of structures (308) forming a first facet set. The first facet set defines a first optical effect device (300) is viewed from a first viewing angle range.
