ABSTRACT:
Patterns are aligned on the front and back surfaces of a document to provide an anti-counterfeiting security device. The document is sufficiently transparent to allow see-through of the partial image on the back of the document to be superimposed on the partial image on the front of the document to form a complete image if the patterns are properly aligned. The complete image will disappear if misaligned.
