Abstract (en)
[origin: WO2004056582A2] The invention relates to a transparent security element for valuable documents, comprising superimposed patterns on two opposing sides of a translucent carrier material. In a precise arrangement according to register, the two patterns complete each other to form a full image forming a code. If the positioning is not precise according to register, the code is illegible. The patterns consist of IR-absorbent material and can thus be read by a machine. A pattern can consist of IR-absorbent and IR-transparent partial patterns such that when observing transmitted light with normal light, a different transparent image can be recognised to that recognised when observing transmitted light with IR illumination.
