Embossed Hologram
When viewed from various angles, the embossed hologram iridescently changes color through the spectrum of the rainbow. lateral 3D effects can be viewed by tilting the hologram left and right. Images are produced by recording the optical interference pattern of the hologram as fine unevenness on the film surface. Embossed holograms are suitable for mass production at relatively low cost.
KALEIDOGRAM®
2D Embossed Hologram
KALEIDOGRAM is a high-brightness two-dimensional (2D) hologram developed by DNP. It uses a high-definition original plate created by electron beam (EB) lithography based on DNP's semiconductor-manufacuring technology.
Fine Line Pattern
Beautiful, fine, bright lines can be produced.
Opto-change hologram®
Color-shifting materials are used.
The label changes color when viewd through a handy viewer, and its authenticity is easily distinguishable.
VIRTUAGRAM®
3D Embossed Hologram
VIRTUAGRAM is a high-definition 3D hologram developed by DNP. The computer-graphics-created 3D rendering ensures advanced design and security. It uses an original plate created by EB Lithography.
Image switching
Different viewing angles provide different stereoscopic images.
Microtext
When the image is enlarged with a magnifying tool, such as magnifying glass or a microscope, "GENUINE" becomes visible.
LED authentication
Hidden Image Authentication by Spot Light Source
Hidden letter or image is retrieved by irradiating spot light source such as LED.

Embossed Hologram Overt and Covert Features
- 1) VIRTUAGRAM®
- Plum blossoms are expressed as 3D images.
- (2) LED authentication
When the hologram is irradiated with an LED light, "JAPAN" becomes visible.
- (3) Morphing
- The pattern shape smoothly changes outward from the letters J, P, and N.
- (4)Image flipping
Different background patterns flips when tilted.
- (5)Microtext
Microtext is hidden at three positions.
(DNP: 300μm; VALID: 250μm; GENUINE: 300μm)- (6)Nanotext
Nanotext is hidden in the band.
(JPN: 5 μm)- (7)Hidden moire pattern
The background has a pattern (☆star) visible when a special film is overlaid.
- (8)Demetallization
Longitudinal wavy lines partially remove the silver metallic layer.
- (9)Contract inversion
Rotating the hologram 90 degrees inverts the contrast.
- (10)Guilloche pattern
A fine geometric pattern is viewd with high brightness effect.
