Materials & Production Developments

AgiLite™: A Novel OVD Security Feature for Document Protection

Neha Agarwal

Sectago (Germany)

Close

SECTAGO’s AgilLiteTM technology is based on an innovative method to create a novel type of diffractive origination. Its creation involves unique mastering equipment, proprietary materials and software. The OVD image derives from a large number of diffractive surface elements which are designed to sophistically interact: Upon illumination the image is synthesized from individually generated light points which are directed towards the viewer’s eye.

 

The image appears bright-white and is customisable within a high degree of freedom, including the representation of numbers, figures, logos, etc. By tilt or rotation of the device the displayed image shows continuous, coordinated motion at high agility, additionally exhibiting a distinct 3D-effect. Hence, it combines the mobility and optical depth of lens-supported security features with the thin diffractive optic of hologram-type devices.

 

The gratings are generated by a mask-less lithographic process with pitch values ranging from <300nm to >5,000nm. Parameter settings are highly variable: pitch, depth and vector angle of the gratings are individually chosen and matched to each other to create the unique optical properties of the feature. Despite its complex origination, manufacturing of this OVD feature has been proven to be cost competitive by means of either standard UV-casting or hot- embossing processes.

 

The basic concept of this new origination technology and a selection of AgilLiteTM examples will be presented. Distinguishing well from other diffractive security features, they are optically attractive, easy to communicate and difficult to counterfeit, altogether making them well suited for the protection of high security documents.

Real Seamless Micro/Nanostructures

Christoph Stoever

Temicon (Germany)

The application of micro/nanostructures on films and components is one of the most powerful technologies to constitute and improve optical, mechanical or biological functionalities. Industrial mass production via roll-to-roll replication (R2R) ensures the economic feasibility of new and innovative products. As the availability of micro/nanostructured imprinting moulds for R2R is limited to welded sleeves, all casted films will show the welding seamline as well. In order to avoid offcuts and enhance production efficiency, film producers aim to eliminate seam lines and push the production towards seamless structured film rolls. According to this demand, our recent work was focused on seamless micro/nanostructured imprinting sleeves. We developed mastering processes for cylindrical substrates, using laser interference lithography. Different structure types have been successfully mastered: Holographic diffusor structures for light management as well as diffractive ‘rainbow’ structures for decorative purposes. One very important result was achieved by generating real seamless sub-µm line grids (down to 200nm pitch), which have no beginning nor end, as they are continuous around the whole sleeve’s circumference. Besides the mastering, an electroforming process to copy the micro/nanostructures from photoresist masters to nickel sleeves was developed. The resulting sleeves have been successfully deployed in a roll-to-roll facility.

Printing technology continues to build on the methods used in traditional secure documents. The technology is now moving into digital fabrication to produce functional features such as printed electronics and 3D devices. This knowledge could also be used to produce a new generation of reflective features for novel document security features.

This presentation will cover 3 main areas where printed reflective features are at various stages of development for application to secure documents.

  1. Metallic layers can now be produced on production scale as the backing to reflective optical features. There are now printing inks and technologies available using both real metal and metal appearance in a variety of colours.
  2. Printed optics continues to be an exciting new field and this presentation will show some of the drivers from other industries that are promoting advances in this field.
  3. Research continues in the printing of tuneable diffractive and reflective elements. This presentation will summarise the various potential options for this technology and where this may lead.

Much of this technology is under development outside of our industry and the presentation will highlight ways to access this knowledge.

Innovations in Origination

E-beam Lithography Originations of Large Format Holographic Movies for Security Optical Variable Devices

Clint Landrock

Electron beam lithography (EBL) has become increasingly popular in the field of computer generated holograms for unsurpassed resolution and flexibility in generating 2D and 3D direct-write nano-structures. However, in comparison to laser or photolithography, direct write EBL systems are limited to slow write times and higher costs, often constraining the holographic images and effects to small, < 1 cm2 areas. Here an origination technique is presented for subwavelength nano-hole arrays that allows for stable and fast write times producing holographic OVD sizes > 5 cm2. This fast EBL origination technique is leveraged for fabricating multiple images encoded within the same optical variable device area at different diffraction angles is shown. This technique of multi-image / multi-directional encoding is used to originate full colour three-dimensional images with wide viewing angles up to 60 degrees, as well as cinema quality colour movie playback of up to 48 frames or equivalent to 2 two seconds of footage recorded at 24 frames-per-second. The originated structures are three dimensional nano-hole/pillar arrays which are suitable for standard holographic OVD foil manufacturing (roll to roll embossing) for security documents.

One-Step Process Fabrication of Holographic Features by Direct Laser Interference Patterning for Individualised Mass Production

Florian Rößler

TU Dresden (Germany)

Close

Origination of holograms typically relies on the fabrication of metallic masters and their replication by embossing technologies, generally as a safety label. Using this approach, high quality and complex holograms can be produced, especially if large quantities are required. However, the standard processing is associated with high investment costs, relatively long processing times and thus a low degree of individualisation i. This characteristic does not satisfy today’s industry demand of individualised mass production as well as the possibility of direct treatments of parts to be protected against counterfeiting without labels

Direct Laser Interference Patterning (DLIP) has been identified as a promising technology for the fabrication of well-defined surface patterns on material surfaces without the need of special atmospheric conditions such as clean room or inert atmospheres. Due to the characteristics of the method, holographic elements such as surface holograms, diffraction-based security features and in-volume holograms can be applied directly in a one-step process on different parts. Furthermore, also the individualisation of conventional E-Beam holograms is possible, enabling new perspectives for individualised mass production processes. This study gives an overview about the DLIP technology for the fabrication of individualized holograms as well as different applications in the mentioned field.

Visual and Security Features Based on Computer Generated Holography

Roman Nahalka

IQ Structures

Computer generated holography (CGH) principles enable new possibilities to the secure holography arena, allowing the creation of completely new security and graphical features.

These structures are generated by a sophisticated algorithm which is similar to the complicated true holographic pattern that is ever-changing and unique in every part of the surface of the hologram. This complexity and non-repeating variability of a diffractive pattern makes optical forgery and even reverse mathematical analysis nearly impossible. By variation of mathematical equations we are able to create a unique appearance and 3D graphical behavior.

In this paper I would like to present a few security and graphical techniques based on computer generated holography which will cover level1, level2 and level3 security features. Using these principles and a simple illuminating device we are able to create a real 3 dimensional full parallax true colour embossed hologram. It gives you the behaviour of volume holograms by an embossed holographic technique which can be mass produced much cheaper than any other kind of the volume hologram.

70 Years of Holography: Past, Present & Future

Lessons from the Past to Enhance the Future

We’ve all heard the saying that if you don’t study history, you’re bound to repeat it. Appropriately, there is much to learn from holography’s 70-year history, some of it bears repeating; some of it should definitely be avoided. In this paper I will look at that history to identify the positives and the negatives and what we can learn from them to help ensure that holography has a strong future. My topics will include patents, the role of individuals and identifying “the next big thing”.

The History of Holography and Document Security Applications

Hans Bjelkhagen

HoloConsulting (UK/Sweeden)

Dennis Gabor invented holography in the late 1940s but it had to wait for its first practical applications until the early 1960s after the laser was invented and laser light could be used for recording high-quality holograms. This happened almost simultaneously in both the USA and the former USSR. Since that time, applications of holographic techniques have been found in science, industry, medicine and art. However, one of the most important applications from a business point of view has been applying holograms as optical variable devices (OVDs) to documents such as credit cards, ID cards, banknotes, travel documents, products, etc. It did not start until the early 1980s after that it was possible to mass-produce holograms using the embossing technique. Large quantities of rainbow holograms could then be produced with a very low price per copy, which made it cost effective to attach holograms to many types of documents. This paper describes how it started, with Steve Benton inventing the white-light viewable rainbow hologram, with Steve McGrew demonstrating the mass-production embossing technique, with American Banknote introducing the MasterCard embossed hologram, until today’s various techniques of OVDs, including kinegrams, dot-matrix and digital holograms, applied to various documents and banknotes as security measures.

The Hologram Foundation and the Holographic Art Grant

Hugues Souparis

SURYS (France)

The Hologram Foundation was created by Hugues Souparis, CEO of Surys, with the objective of helping visual artists work with holography. A foundation by French law the Hologram Foundation’s mission is to support artists in the creation of holograms that are designed for easy display anywhere and contribute to making holography one of the components of contemporary art.

Hugues Souparis is a pioneer-entrepreneur in the field of high security holography. He received the Award for Creative Audacity from the French President in 2012. His company Surys (formerly Hologram Industries), established in 1984, provides holograms on security documents and currency for more than 100 nations. Souparis wants to support and promote art, creativity and innovation:

“After 35 years in holography business, I want to help visual artists who choose holography as their primary medium. I believe that holography remains one of the most “magic” mediums. Every time the public is exposed to holograms they are fascinated. I want to help artists to bring this fascination to art appreciators”.

Created and financed by the Hologram Foundation (Paris) with the support of the Center for the Holographic Arts (New York), the Holographic Art Grant supports the production of art holograms.

Through an international competition, six artists were selected according to criteria of artistic quality, originality and ease of installation of their work in everyday settings.

The exhibition IRIDESCENCE presents art holograms created through the first round of The Holographic Art Grant. IRIDESCENCE was in Paris from May 27 to June 18 and from September 1 to October 29, 2017 at the HoloCenter in New York City.

Some of the works are for sale, with the full proceeds going to the Hologram Foundation funding pool for art hologram production. The next round of the international competition will be announced in late 2017.

Securing Documents and Brands

Another Approach to Brand Protection Using Holograms

Kamata Yasumasa

Toppan (Japan)

For the market of brand protection, Toppan Printing has established a new technology that enables machine confirmation of authenticity by simply using a smartphone to scan a specially-designed hologram.

Holograms are widely used as a counterfeit prevention tools that address such needs. In particular, holograms that enable visual confirmation of authenticity without the need for dedicated devices have been well-received because services using them are easy to roll out to consumers. However, although visual confirmation is possible when the authentic product and counterfeit are both close at hand and can be compared, this is rarely the case, and consumers find it difficult to accurately confirm the authenticity of counterfeits that look similar to the real thing.

With conventional holograms, the hologram pattern is recognised as a designed image. However, we have established a unique authentication algorithm that uses optical analysis technology. Authentication is possible even with holograms whose appearance seems to be the same.

We have now combined special hologram technology with high-accuracy optical analysis technology to establish a means of automatically confirming authenticity by scanning with a smartphone on which the dedicated application has been installed.

Furthermore, as an expansion of the service, it is proposed to be utilised as an introduction for reading the unique ID of the product.

With this technology, we hope to contribute to preventing losses caused by counterfeit and imitation products.

ITMO University of St. Petersburg in cooperation with the Hellenic Institute of Holography (HiH) have been officially invited to create full-colour Denisyuk-type holographic OptoClones of selected Russian State Treasures belonging to the Diamond Fund of the Russian Federation. These selected artworks are considered not only an invaluable part of the national historic heritage of Russia but are also protected as ‘State Treasures’ due to their inherent value in terms of their content in precious minerals and metals. Some of the selected treasures are prominent exhibits from the Moscow Kremlin Museum; some will come out from the vaults of the Diamond Fund for the first time for the purpose of being holographically documented. The produced OptoClones will be subsequently used for exhibition by the owner of the treasures instead of the original artefacts and will be therefore delivered with individually incorporated HoLoFoS, the proprietary RGB LED-illuminants developed by HiH. The participants of the Holography Conference 2017 will be the first to learn of the project details and appreciate preliminary samples of the produced OptoClones. What better way to celebrate the 70th anniversary since the invention of Holography!

For more than 20 years, holography has been introduced in the world of solar energy, mainly in the design of devices used in photovoltaic, solar thermal, solar control, lighting, energy efficiency, among others. Although these applications have been successful, they have not been able to cross the laboratory barrier with the real world. Nowadays, with the growing interest in the use of renewable energies, together with the capacity to generate a mass production of high-quality holograms, the interest of holography for solar applications has increased, opening a new stage to the Holography in this sector.
