Abstract (en)
[origin: WO9710107A1] An article (12), especially when in sheet form such as a document and which carries insignia like letters and numerals on a first side, is rendered tamperproof by adhering a transmissive (16), e.g. transparent layer to the first side of the article over the insignia (14), and severing the article from a second side opposed to the first side, e.g. by means of cuts, which do not penetrate through the transmissive layer (16). A second layer (18) can be adhered to the second side and the layered article can be severed also from the first side, e.g. by means of cuts which do not coincide with the cuts from the second side and which do not penetrate through the transmissive layer (16). The portions of the article carrying the insignia (14) are held in their original orientations and positions by the intact portions of respectively the transmissive layer (16) and the second layer (18). If the insignia are accessed, e.g. to alter the insignia, the portions carrying the insignia (14) are no longer held in place, which is readily detectable.
