Abstract (en)
[origin: WO2018191827A1] The security document comprises a window (6) with an invisible, printed refractive, non-diffractive structure (7) printed thereon. In addition, it can carry a visible printed image (8). When the window is viewed against a dark background, the structure becomes visible and thereby allows testing the document's authenticity.
