Photopolymer Holograms Top Pira's List of Disruptive Technologies in Security Printing

LEATHERHEAD, UK—August 17, 2010—Photopolymer holograms are set to be the most disruptive technology to impact on the security printing industry, according to a new Pira International study. "Ten-Year Forecast of Disruptive Technologies in Security Printing" identifies innovations that will have an impact in a way that is discernibly disruptive, as opposed to technologies that simply bring about incremental changes within the security print industry.

Based on extensive primary research and expert feedback from a panel of senior executives across the security industry, the study identifies the top 25 most significant technologies with respect to their disruptive potential and their likely evolution over the next 10 years.

The top 10 disruptive technologies are:

1. Photopolymer holograms
2. Micro-optical Arrays
3. Moiré OVDs
4. Computer to Intaglio Plate Technology (CTIP)
5. Windows in paper substrates
6. Optically Variable Magnetic Inks (OVMI)
7. High-resolution De-metallization (HRHD)
8. Zero-order diffraction devices
9. Durable Banknote Substrates
10. Laser ablation featuresSource:

Photopolymer Holograms
According to Pira, photopolymer holograms are set to become a significant disruptive technology in security printing not only because of the revolutionary advances in substrates and imaging capability but also because they will change the way people look at secure documents.

Looking back, one of the most disruptive technologies in security printing over the past 30 years has been the embossed rainbow hologram, introduced by American Banknote in the early 1980s on credit cards. This new medium became the dominant form of visual authentication for both brands and secure documents by the early 1990s having displaced rival products such as Polaroid’s Polaproof.

The introduction of holograms or more correctly Diffractive Optically Variable Image Devices onto banknotes was a more gradual process, having first been introduced in 1989 it was not until the late 1990’s that it showed truly disruptive potential, when the number of DOVIDs on banknotes went up 500% from 1997 to 2002. In the same time-frame however the sales of Dot-Matrix systems for making digital holograms which could simulate sophisticated optical devices, such as the Kinegram®, became widespread and within five years the first high-quality counterfeit euro banknotes with Dot-Matrix generated fake DOVIDs appeared. This sparked off a race to develop new Optically Variable Devices (OVDs) that looked entirely different from embossed rainbow holograms.

Photopolymer Holography has undergone some dramatic changes since the original Lippmann type hologram. The principal difference between embossed DOVIDs and holograms recorded in photopolymer is the direction of the interference fringes. In an embossed grating or hologram, minute regular undulations in the surface diffract incident white light into the colours of the rainbow.  The surface relief may be in the form of a sinusoidal cross-section, or a triangular ‘saw-tooth’ or a crenelated ‘top-hat’ profile, but they all have to be open structures, so that they can be replicated by embossing.  Photopolymer holograms and gratings are typically recorded within the body of the material, so that the light-diffracting fringes are parallel to the surface, like pages in a closed book.

Its good to hear, that hologram proves again. Holographic OVDs which have been used by more than 100 issuing authorities on over 250 banknote denominations worldwide, including the launch of 12 billion Euros notes in 2000. In a recent survey also, by Dutch National Bank to measure the public understanding of security features, it was revealed that out of seven selected features, the Hologram came out second with 55 per cent public recognition, beaten only by the watermark (76%). These prove the ability of hologram as the most easily identified overt security technology. Further holography is the only technology one can incorporate multiple layers of security (Overt, Covert & Forensic Security).

Banknote security is an extremely important issue. With the popularity of technologies such as colour copiers and scanners, making forgeries of banknotes is getting easier and easier. Thus, security features have to be at the top of the technology specter.
