  • Printed security device and method
    Patent number: 6918616
    Abstract: According to one aspect of the invention, a printed security device for a document comprises an intaglio printed latent image which has been printed onto a substrate using a highly reflective ink, wherein the intaglio printed latent image is visible when viewed within a first angle range extending from near-vertical to the plane of the latent image towards the image and also within a second angle range closer to the plane of the image, and is not visible when viewed within an angle range between the first and second angle ranges. A change in viewing angle from one angle range to an adjacent angle range results in a visible latent image becoming invisible or vice versa (creating a flip-flop image visibility effect).
