A self-verifying security document, such as a banknote, comprises a flexible sheet formed from a plastics substrate bearing indicia. The sheet has a window of transparent plastics material that includes self-verification means for verifying a security device provided at a laterally spaced second portion of the sheet when the sheet is bent or folded to bring the window into register with the security device. The self-verification means may be an optical lens for reading an area of microprinting. In another embodiment, the self-verification means may be an optical filter for viewing an area printed with metameric inks. In other embodiments, the self-verification means and the security device may be polarizing windows or Moire inducing patterns.

Self-verifying security documents

A printed document or other device comprising a polymer substrate having a surface to which printed matter is applied, a reflective or brightly colored layer applied directly to said surface by means of a printing process, and a printed image applied to the reflective or brightly colored layer by an intaglio printing process.

Printed matter producing reflective intaglio effect

A self-verifying security document, such as a banknote, comprises a flexible sheet formed from a plastics substrate bearing indicia. The sheet has a window of transparent plastics material which includes self-verification means for verifying a security device provided at a laterally spaced second portion of the sheet when the sheet is bent or folded to bring the window into register with the security device. The self-verification means may be an optical lens for reading an area of microprinting. In another embodiment, the self-verification means may be an optical filter for viewing an area printed with metameric inks. In other embodiments, the self-verification means and the security device may be polarizing windows or Moire inducing patterns.

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 &ldquo;half-window&rdquo; 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.

Banknotes incorporating security devices

A self-verifying security document, such as a banknote (,) comprises a flexible sheet formed from a plastics substrate (,) bearing indicia (,). The sheet bas a window (,) of transparent plastics material which includes self-verification means (,) for verifying a security device (,) provided at a laterally spaced second portion of the sheet when the sheet is bent or folded to bring the window (,) into register with the security device (,). The self-verification means may be an optical lens (,) for reading an area of microprinting (,). In another embodiment, the self-verification means may be an optical filter (,) for viewing an area (,) printed with metameric inks. In other embodiments, the self-verification means and the security device (,) may be polarising windows (,) or Moire inducing patterns (,).
