DNP Develops World's First Lippmann Hologram Cards with Improved Security
Cutting Edge Security Hologram Provides High Anti-Counterfeiting Performance in ID and Membership Cards
Dai Nippon Printing Co., Ltd. (hereafter referred to as "DNP") is pleased to announce that it has successfully developed the world's first Lippmann hologram cards, which are extremely difficult to counterfeit yet allow for easy verification of authenticity by visual inspection. DNP will begin sales of the new hologram cards on April 1, 2010.
DNP will provide two types of cards: cards with embedded and integrated Lippmann holograms aimed at preventing counterfeiting of the cards themselves, and cards covered by Lippmann holograms aimed at preventing falsification of the information contained on the cards. These cards will meet demands for applications such as ID and membership cards.
[Background of Development]
Many ID and membership cards requiring security have holograms on the surface to prevent counterfeiting and falsification. Previously, these cards used embossed holograms. However, improved security has been in demand both for the cards themselves and for the information on the cards, as well as easier verification of authenticity. Lippmann holograms, which provide full-parallax three-dimensional images with a realistic sense of depth, are extremely difficult to counterfeit because they require special materials and manufacturing processes. DNP has established mass production facilities for Lippmann holograms and currently provides product authentication labels, anti-counterfeiting stickers, and transfer foils for passports, etc.
Recently, DNP has made advances in its materials and manufacturing processes that have led to the development of the world's first Lippmann hologram cards, aimed at use as ID and membership cards.
[Product Overview and Features]
1. Partially processed cards: preventing counterfeiting of the cards themselves
Full-parallax three-dimensional images with.a realistic sense of depth. The image changes with the viewing angle.
- Part of the card is embedded with Lippmann holograms. The Lippmann holograms are inserted between the base material and surface layer of the card to improve durability of the holograms and to prevent counterfeiting of the cards.
- Various sizes and shapes of holograms can be used. The holograms included can be customized in accordance with the design or use of the cards, and can include appealing logotypes.
2. Entirely transferred cards: preventing counterfeiting and falsification of the information on the cards
- The entire surface of the card is covered by Lippmann holograms. The holograms prevent falsification of the photograph or text information printed on ID or similar cards.
- When the cards are issued by the card printer that prints variable information such as the photograph and name of the card holder, Lippmann holograms that fit the size of the card are simultaneously transferred onto the card.
[Effects of adding Lippmann holograms]
The diverse range of images that can be expressed using Lippmann holograms, together with its use alongside other security printing technologies, adds further value.
- Lippmann holograms allow for more realistic three-dimensional images that change with the viewing angle when viewed from any direction, both vertically and horizontally.
- Lippmann holograms further increase security when combined with high-precision two-dimensional images, micro-text of approximately 10 micrometers, and laser reproduction images.
DNP will provide these cards for applications such as ID cards requiring high security and membership cards for upscale resort facilities, and aims to achieve sales of five hundred million yen by fiscal 2012. DNP will exhibit the cards at IC CARD WORLD 2010, from March 9 to March 12, 2010 at the Tokyo International Exhibition Center (Tokyo Big Sight).
[Hologram Reference Information]
The surface of a film is coated with a special polymer layer, in which changes in the refractive index produce interference patterns. When light is projected onto these interference patterns, holographic images are reproduced via the diffraction phenomenon. Lippmann holograms offer a superior full-parallax three-dimensional effect in both horizontal and vertical directions with a realistic sense of depth, making it possible to create close renditions of real-life objects. Lippmann holograms use special materials and manufacturing processes, making them extremely difficult to counterfeit. Lippmann holograms have developed a global reputation for security performance due in part to their ability to accurately render specific design attributes, as they enable designs incorporating a realistic sense of depth and full-parallax effect.
