ABSTRACT:
A method and product for making counterfeit resistant security document. The document has a first set of printed lines which form a latent image and a second set of printed lines at an angle relative to the first set which forms a background image. One of the sets of lines is embossed so as to render the latent image visible only when viewed from pre-determined non-perpendicular angles relative to said document.
