Abstract
A security document ( ), such as a bank note, is formed from a sheet-like substrate ( ) of clear plastic material with layers ( ) of opacifying ink applied to the surfaces ( ) of the substrate ( ). The security document ( ) includes a security device ( ) which is at least partially obscured by the layers ( ) of opacifying ink on a flat surface ( ) of the substrate ( ). The layers ( ) on the second surface ( ) of the substrate ( ) are applied in such a manner so as to leave a “half-window” area uncovered by opacifying ink through which the security device ( ) is visible for one side of the document ( ). The security device ( ) may extend transversely outside the half-window area and be visible in transmission, enabling a different contrasting effect to be observed from both sides of the document.
