Abstract:
1. A pharmaceutical dosage form combination with reduced susceptibility to counterfeiting, comprising: a pharmaceutical dosage form including a surface or interface; a Moiré pattern base layer formed directly on the surface or interface of the pharmaceutical dosage form such that the base layer cannot be removed from the pharmaceutical dosage form without destroying the base layer and the pharmaceutical dosage form; and a Moiré pattern revealing layer through which the pharmaceutical dosage form may be viewed, the revealing layer being separable from the pharmaceutical dosage form, wherein the Moiré pattern base layer and the Moiré pattern revealing layer form a Moiré pair that produces a contrast visible to the human eye and wherein a Moiré effect is seen by an observer by looking through the revealing layer, when the revealing layer is positioned relative to and spaced from the base layer.
