The story started from student experiments on holography and digital optical processing in Warsaw University of Technology. Computer generated holograms were calculated using ZX Spectrum microcomputer, drawn by a big plotter and photographed with an analogue camera with film replaced by small glass plates leading to holographic effects eg. multichannel asymmetric hidden images, used still today in the holography industry.

After joining Holografia Polska company and building the first HoloMax – computer generated hologram machine for internal use – the second step in the development was to produce a machine for Holographic Systems Munchen.

The third step was to develop a machine that could be used by security hologram producers who required in-house origination, but did not need a strong scientific background. This lead to the first Kinemax systems that utilised high-resolution diffraction grating patterns to make various types of rainbow holograms. The equipment is extremely design flexibile and does not require the hassle of operating extremely expensive, big size analog holographic equipment.

The next steps were the development of a litho head and the further development of speckle-less recording of microoptical elements, like lenses, blazed gratings and/or synthetic holograms.

The technology has been extended to record high frequency gratings that can be applied to produce intelligent diffusers for photovoltaic applications.

Nano-optical elements – a new breakthrough direction in security technology.

Electron beam origination technology is used in the production of originals of the nano-optical elements. The technology is well protected against counterfeiting or imitation by both the high price of e-beam equipment and the complexity of the technology. E-beam technology provides a wide range of security features for visual control. DeColor effect is an example of such security feature based on asymmetrical microrelief. The effect is easy for verification: from a normal viewing position an observer sees one image, but after rotation of an element through 180 degrees, an observer sees a different image in the same place.

The security feature is well protected against counterfeiting by the 10 nanometers accuracy of the microrelief fabrication. Another example of security features for visual control is the SmartGlint effect, which forms a full and wide ranging parallax movement of symbols.

Breakthrough technology for automatic verification of CLR (Covert LaserReadable) images has also been developed. The handheld portable reader for the CLR feature allows sure and quick verification procedure of nano-optical elements.  These developments are already in wide use for protection of passports, bank notes, IDs, excise stamps and brands in many countries.

In the 1980s and 1990s holograms were used on many products, such as, books, children’s books, journals, comics, toys, cereal boxes, etc., including music records. In June 2016 Disney Music released Star Wars: The Force Awakens vinyl record with a hand-written hologram. Because of this event, it may be interesting to present a historic review of the most interesting display holograms which have appeared on products. This application is only as a decoration or as a point of purchase purpose and not as a security device – the main application of commercial holography. The first mass-produced hologram was the 1972 The King’s Ring hologram, inside a Quaker Oats cereal box.

When the embossed hologram technique was introduced in the early 1980s, it became the main hologram type used on products. Not until an embossed display hologram appeared on the National Geographic cover in March 1984, did the use of holograms on books, journals and other products take off. Very often the products using holograms were issued as limited-edition or special collector’s items. Around the year 2000 most of these applications disappeared, mainly because of the problem of incorrectly displaying product incorporating holograms in shops.

Since the first hologram was developed in 1947 by Dennis Gabor, holography has significantly evolved generating a great number of applications in different fields as art, metrology, medicine, biology, security, advertising, defence, photonics, etc. Some of these applications crossed the barrier between laboratory and industry but others had to wait long time to take a leap forward. An application still under research is holography for solar energy purposes. The idea relies on being able to produce compact and functional applications easy to industrialize at low production costs. Unfortunately, it is not trivial to generate industrial holograms with high efficiency, broad spectral and angular bandwidth, resistant to harsh environmental conditions, flexible and with reduced costs for such applications.

Currently, the ‘Instituto Holográfico Terrasun S.L.’ (IHT) company owns an industrial mass production process for high efficient and broadband volume holograms; 99% relative diffraction efficiency, ~250nm spectral bandwidth and ~40º angular bandwidth. IHT has successfully designed, developed and tested revolutionary applications with compact designs that involve the use of efficient holograms actuating together with a 3D structure to trap, guide and concentrate the solar energy radiation. In this work we will present such applications and the achieved relevant results.

Idvac Ltd., UK, has developed an innovative process to add extra overt features to the design of holograms. In this process, bright colours of Green or Blue can be vacuum metallized inside a standard vacuum web metallizer to produce holographic effect with distinctive colours instead of the standard silvery aluminium finish.

Holograms are known to be metallized fully or partially with aluminium or   copper for full reflectance or with zinc sulphide for semi-transparent effect.  However, in this new innovation new colours such as green to blue can be vacuum metallized without the use of any inks, dyes or wet coatings. The process is dry and is done in vacuum. Different shades of semi-transparent or high reflectance green or blue colours can be produced on embossed or non-embossed films.

The innovative process can be used for laminated or hot stamped security or decorative holograms or for Banknotes. It can also be used to produce bright and shiny holographic stripes with unique colours.

Printing is evolving from the production of static graphic features such as those used to produce secure documents. Advanced printing technologies such as inkjet are now being used to produce functional features such as printed electronics and 3D devices. These technologies could also be used to produce printed optical devices for new and novel document security features.

This presentation will cover four main areas where printed optical features are at various stages of development for secure document applications.

  1. Gloss features can be produced using print and inkjet gives a number of options for these. Some of these have been market tested over a number of years, predominantly for low level documents.
  2. Printed optics is an exciting new field with plenty of potential for secure document features. Microlens arrays have been embossed into laminates and plastic cards for some years but these sort of features can be digitally printed too.
  3. Liquid crystal systems offer some interesting potential, particularly for brand protection as a printed optically variable feature on a label.
  4. For the future, fully printed displays could provide some very strong optical features. There are however still some impediments to the realisation of these technologies for secure documents.

The need to provide a secure and easy to authenticate optical security device has been a focus of development for many years. The need has been particularly felt within the ID industry where border control agents have only a matter of seconds to decide if a document is genuine or fake. Visibility and simplicity is the key as recognition of the primary visual feature is vitally important and yet sophistication and complexity of any new technology is needed to minimise the counterfeit risk. It is this primary visual feature that is at the centre of many new developments within the industry, to provide visual features that are more effective, difficult to counterfeit and easier to authenticate.

From analysis of leading developments within the past year, it is becoming clear that there is a convergence of developing technologies focussing on colour control and colour shift by many of the leading exponents of OVD and DOVID technology to address the ‘easy to see’, ‘easy to understand’, ‘difficult to replicate’ criteria. It is also well known that materials such as nail varnish and paints can simulate simple security colour shift effects, so more complex colour effects are created using specialised coated materials.

In this presentation I will show a new generation of colour control and colour shift using holographic technologies and control of the phase of the diffracted light using structures that requiring no coatings or special preparation. The principle will be described based on a combination of complex diffraction spectra and interference effects to control the light diffracted toward the observer. Samples will be shown together with full holograms containing these additional security elements.

Nano-optic based optically variable devices (OVD) can be leveraged to generate novel optical effects, however, the observed optical effect that can be generated in the laboratory is almost always imperfectly translated to the actual security document substrates in production, particularly in direct embossments compared to casting techniques. In this paper, we explore how low-aspect ratio sub-micron structures in metallic electroformed shims can benefit from improved hardness and strength due to characteristics unique to the nano-scale.

The improvement in hardness and strength translates to high fidelity replication of novel optical effects during direct multiple embossment strikes into a wide variety of substrates including metals and bio-materials. These structures can open the door to direct embossment into a wide variety of security document substrates, rather than the transfer of OVDs via release layers or hot/cold stamping.

The advantages of direct embossment over surface-applied features include: reducing the overall cost of the secure document through a reduction in the number of fabrication steps, increasing the security by eliminating the possibility of removing the OVD from the document, expanding the field of use of OVDs to areas where transfer foils are not applicable (e.g. coins), and possibility of application on new polymer and hybrid secure document substrates. Each of these are briefly explored in this paper.

Holography and other different embossed effects have a great variety of uses in industry, from security applications to packaging; this leaves us with a large range of production specifications, origination sizes and other challenges to tackle. In order to identify the key requirements for each origination technology and its applications, some important considerations have to be taken into account by the hologram manufacturer. In this talk , we will describe the differences, advantages and disadvantages among the origination techniques, in terms of production, recombination and use. We will discuss diffractive and non-diffractive effects, their needs in terms of groove depth and their impact in the reproduction techniques. Finally, we will briefly discuss the solutions to the market needs that the CI team brings to the table.

Session Five: Panel Discussion

09.15 - 10.30

Holography for banknotes is currently undergoing something of a renaissance. This is due in no small part to recent developments in polymer notes in particular, with the new series in Canada, New Zealand, Australia and the UK all featuring holographic effects that are as ground-breaking as they are eye-catching. This panel discussion will comprise the main stakeholders in the development of holograms for polymer banknotes and will cover the challenges raised, and hurdles overcome – to achieve a new standards in holographic design, material science and security.

Choosing an OVD for Securing Your New Banknotes - a Central Bank's Perspective

On September 16th, 2014, the Bank of Israel (BoI)launched the new NIS 50 banknote—the first denomination, out of four, in Israel’s new series of banknotes. It is the first ever circulating banknote to carry a KINEGRAM VOLUME® foil stripe.

KINEGRAM VOLUME from KURZ was selected by the BoI as one of the major security features for the new banknotes of Israel. The new series of banknotes presents advanced standards of security, innovation and accessibility.

The BoI’s team started working on the project in 2011. It was decided at an early stage to use a foil feature as principal security element for all four denominations. In the BoI’s view, an important advantage of foil is the high counterfeiting resistance of such features. The BoI was convinced of the feature’s anti-counterfeiting capabilities as it is so fundamentally different from the foil features that were used on banknotes up to this date.

Furthermore, foil features are easily detectable and thus usable for authentication by the general public and can be easily communicated.

The presentation focuses on the Bank’s reasoning and perspective within the process of choosing an OVD as one of the major level 1 (public) security features, together with some other aspects of the project.

In the past, all ID documents were made out of paper and durability and tampering were constant issues.

Nowadays ID documents must be clean, durable and very hard to falsify.

Over the years, plastic has become the most common material for ID documents. Most ID cards are now made of polyester, PVC or polycarbonate. Even a significant percentage of passport data pages have turned to plastic.

In the recent years, polycarbonate has become the preferred material for ID documents.

While paper documents could be authenticated with an ‘embedded’ security feature such as a watermark, today the most widely used visual security feature used for polycarbonate ID documents is DOVIDs.

SURYS is one of the major suppliers worldwide of embedded features in polycarbonate documents, with numerous references in ID cards, passport pages and driving licenses in Europe and throughout the world.

The presentation includes a description of the optical effects generally used in such an application, the process of integration, as well as a review of relevant examples.

A new combined embossed hologram originating technique was developed by the international team of holography experts. The technique merges deep 3D holographic images with commonly used hologram security features. Deep 3D images were first recorded on photoresist with Geola’s holographic printer containing their proprietary pulsed laser. Optical security features were then overexposed onto the photoresist plates containing latent images of deep 3D scenes. The photoresist plates with several exposures (containing optical security features and deep 3D images) were developed. Embossed holograms, containing such effective public security features as full colour 3D images, guilloches, rainbow patterns were manufactured. Manufactured embossed holograms also contained such optical security features as micro text and laser readable hidden image.

From bottled water to expensive chemical products, how can one prove a bottled liquid is the original one? The liquid can be tampered with in its original bottle, or the whole packaging can be imitated. Possible routes to prevent this include tamper-evident security labels or liquid tagging itself.

We will present cases where neither approach is viable due to cost or complexity. A new solution of integrating the security as an integral part of the primary packaging without any additives will be shown. When smartly used on tamper-evident/anti-refill parts, it guarantees the originality of the liquid inside – with instant authentication, no additives, and passport-grade anti-counterfeiting barriers.
