Abstract
Official abstract text for this publication.
Disclosed is a composite security element and a method for applying the same to a substrate (e.g., paper). The composite security element has a first pattern mark and a second pattern mark. The first pattern mark is marked in first (active) marking material (e.g., ink) and the second pattern mark is marked in second (passive) marking material. When exposed to light or radiation at wavelengths in the visible spectrum, the first and second pattern marks are indistinguishable from one another (to a naked human eye). When exposed to radiation at least some wavelengths outside of the visible spectrum, the first and second pattern marks are distinguishable from one another (e.g., first pattern reacts to non-visible light). The first pattern mark may be a security mark or symbol, for example. The marking materials may be colorless. Both first and second pattern marks are also associated with similar gloss.
