ENGRAVED OPTICALLY VARIABLE IMAGE DEVICE |
摘要 |
A method and image made by the method is disclosed wherein non-spherical magnetically alignable optical pigment flakes in transparent carrier are applied to a substrate and are aligned by applying a magnetic field to the substrate. The pigment flakes align a long magnetic field lines and a tool for impressing or scribing the flakes is applied to a sub- region of the substrate to realign or remove flakes from a desired region. For example a scribing tool can be used to scribe a signature or other marks within the magnetically aligned flakes. The flakes are then cured and the image is preserved which has optical and tactile features. |
