The optically variable element (2) is integrated with the carrier (1), in this case a banknote, so that an optical effect is visible when either side of the banknote is viewed. The element is an embossed line or lines, a dash, points, curved or straight black lines (3). The element has raised sections (4) and hollow sections (5) in two different colours (6,7). On the back of the document, in the region of the element, an underlying stratum (8) is pressed, in one or more colours in this area. The colour printed area (6) is visible from angle alpha and the other colour (7) from the angle alpha'. |
