  • Graphic works involving holography
    Patent number: 5889598
    Abstract: A substrate bears holographic imagery, selected portions of which are covered by non-holographic imagery printed in predetermined geometric registry with the holographic images. Multiple replicas of this interactive graphic work are mass-produced by embossing an array of the holographic imagery into a substrate in roll form, together with eyemarks located periodically along the roll. Using these eyemarks, the roll is optically sheeted and the non-holographic imagery then printed on the holographic substrate.
