E-LIDOGRAM® HOLOGRAPHIC CARD OVERLAY – SECURITY FEATURES
Level 1 – Identification with human eye
1. 3D pastel colour sculpture effect
Creating a strong illusion of shape and depth, the element displays matte pastel-coloured figure which appears to stand out against a flat surface giving the impression that the figure has been raised above the background plane.
2. 3D achromatic sculpture effect
The element displays achromatic characters which appear to stand out against a flat surface giving the impression that the characters have been raised above the background plane and creating an illusion of shape and depth.
3. Full-parallax motion effect
An unambiguous naked-eye feature displaying full displacement in the apparent position of an object with distinct up-down and left-right movements depending on the viewing angle.
Level 2 – Identification with special devices
4. Multi-plane dynamic image “e-Motion”
Lens magnification-based feature displaying an object moving in both horizontal and vertical directions when illuminated with a point source light.
5. Covert laser-readable image
Covert feature consisting of a static image invisible to the human eye and revealed when illuminated with a simple laser device.
6. Dynamic hidden image
Invisible to the naked eye, an image of the running lion and morphing of letters DH and OK are revealed when the feature is illuminated with a laser device
7. Non-periodic micro-text
Visible through a magnifier, the feature reproduces text characterized by a lack of periodicity
Level 3 – Expert control identification
8. Nano-hatching
Visible through a microscope, the feature reproduces text dispersed randomly in the diffractive grating with letter thickness similar to the grating period.
9. 3D Nano-sculpture effect
Three- dimensional images and characters visible through a microscope providing water-tight forensic-level security.
10. Half-tone raster
Continuous tone imagery displaying the symbol sized between 12 and 55 nm to generate a gradient-like effect seen under the microscope.
