Abstract
An article having a surface bearing patterned indicia having micro-structures. A surface is provided with contrasting micro-structured features that form perceptible indicia or pattern having a recognizable pattern in reference to a background surface. The background surface is a micro-structured surface, on which perceptible indicia having the recognizable pattern of micro-structures are formed. The pattern of micro-structured features includes raised and/or recessed structures with respect to the substrate surface. The micro-structured surface includes irregular prisms forming structural features or topography within a plane of longitudinal rows of regular prisms. The indicia in reference to the background plane are perceivable, without requiring contrasting colors between the indicia and the background.
