Dai Nippon Printing Develops Transfer-Foil-type Lippmann Hologram for Plastic Cards
Applications Include High-Security Identification and Exclusive Membership Cards
Dai Nippon Printing Co., Ltd. (headquarters: Tokyo; president: Yoshitoshi Kitajima; capital: 114.4 billion yen; hereafter referred to as DNP) has developed a Lippmann hologram of various shapes and that can be hot-stamped onto plastic cards for which high security and premium design are requirements, including ID cards and product warranty cards. For foreign manufacturers of high-security plastic cards, DNP will provide the product as hologram transfer foils or as plastic cards bearing Lippmann holograms. The product will be commercially introduced from April 2016.
Many cards, including ID cards associated with high security and authentication requirements, exclusive membership cards that need to project a premium feel, and product warranty cards, currently feature embossed holograms against silver backgrounds that display the colors of a rainbow when viewed from different angles. These holograms also create a three-dimensional visual effect when shifted left and right. However, advances in counterfeiting technologies in recent years have resulted in the emergence of increasingly authentic-looking counterfeit cards. This, in turn, has generated demand for Lippmann holograms, which offer both stronger anti-counterfeiting properties and easy visual authentication.
Lippmann holograms, which feature three-dimensional images characterized by a great sense of depth, superior design properties, and high security performance—meaning the holograms extremely difficult to copy—have won acclaim worldwide. Lippmann holograms are incorporated as countermeasures against counterfeiting in product packaging, in warranty cards for brand-name products, and in credit cards.
DNP began manufacturing Lippmann holograms in 1992. By 2010, it had developed plastic cards that featured embedded Lippmann holograms, in which the holograms are sandwiched between the multiple plastic films making up the card. At first, these cards had to be manufactured at DNP factories in Japan. Since then, DNP has received requests for its Lippmann holograms from overseas companies wishing to use them in manufacturing plastic cards manufactured locally at their factories. In response, DNP developed a Lippmann hologram that can be applied on card surface using a hot press machine.
[Product Overview and Features]
Lippmann holograms are manufactured by coating films with a special polymeric material and altering the density of the interior of this material to form interference patterns due to changes in refractive index. The diffraction of light striking the interference pattern generates three-dimensional holographic images characterized by a great sense of depth. Due to the sophisticated technologies required, few companies in the world are capable of producing Lippmann holograms. DNP is one of these companies. In particular, DNP was the first to mass-produce Lippmann holograms successfully and possesses the strongest design and representation technologies for these holograms.
For the present product, DNP developed a Lippmann hologram with an innovative layer composition characterized by thinness and excellent workability, allowing users to apply holograms of various shapes onto plastic cards. This Lippmann hologram product can be transferred onto plastic cards using a commonly-used hot press machines.
Lippmann holograms present a three-dimensional image when shifted left and right and up and down, generating a more lifelike image than embossed holograms. These sophisticated holograms allow individual consumers and businesses to verify card authenticity at a glance, thereby enhancing security performance. The superior design properties of DNP Lippmann holograms also provide users with access to more elaborate designs and help confer an exclusive feel to product warranty cards and membership cards.
By supplying cards bearing Lippmann holograms to companies that issue ID cards and product warranty cards, as well as hologram transfer films to plastic card manufacturers, DNP is targeting cumulative sales of 500 million yen over the three-year period to FY2018. Moving forward, DNP will continue to develop advanced security printing technologies and to produce products incorporating such technologies.
