A security feature, by which a genuine document can readily be visually distinguished from a reproduction, employs finely detailed, laterally spaced structures to yield the illusion of a 3D texture. When replicated using commonly-available scanning or printing devices, the fine detail is lost, and with it the 3D illusion.
