About The Holography Conference 

Michael Grau

Michael Grau has worked in the printing industry for over 30 years and has been with Gietz since 2012. Michael started his career with an apprenticeship as a printer in the commercial printing industry and went through all areas of modern printing companies. With further studies as technician in printing technologies in a part-time-course, he progressed into different print management positions and ended up as Technical Director as well as General Manager in the printing industry. In the early 90ties he got in contact with the hot foiling process. Since then this technology became not only his job, but also his patience. With this technical background, he joined then the Gietz family in 2012 as Area Sales Manager and has taken over the position as Sales Director at Gietz in mid-2016.

Phil Holland

Phil Holland has worked in the printing industry for over 40 years.

A time served lithographic printer who studied origination, pre-press, letterpress, and sheet fed printing, Phil progressed to print management in the public sector and then made the transition to capital equipment and print machinery sales.

Formally Phil was General Sales Manager at Komori UK with responsibility for the sale of sheet-fed presses and ancillary equipment in the UK and certain distributors in countries such as Africa.

Phil joined Komori Currency Technology in early 2009 and is currently Sales Director with the responsibility of continuing to increase the market share of Komori in the Banknote and Security Printing industry.

Phil is also a board member of the International Currency Association (ICA) and is a strong advocate for cash and that it remains part of the payment landscape, now and in the future.

CHIMERA™ Masters and New Industrial Contact Copy Machine

by Philippe Gentet

We present a new automated industrial copy machine able to mass-reproduce by contact full-color CHIMERA digital holographic masters on photopolymer materials—with instant dry processing—for security, automotive industry, and display applications. CHIMERATM printers are the third generation of full-color and ultra-realistic holoprinters. They print computer-generated color reflection hologram masters on UltimateTM (U04) silver-halide photo-material glass plates with a size up to 60×80 cm. CHIMERATM masters present unique features compare to the previous technologies available today on the market. They have 120 degrees full-parallax (horizontal and vertical), surface grid invisible to the human eye (250 microns) and high brightness, delicate and vivid colors with deep gray levels. In addition all special effects can be integrated into the final holographic image, such as multiple channels and markings.

Philippe Gentet

Philippe Gentet is a French engineer who works in the field of holography since the end of the 90s. He is currently researcher and PhD. candidate at Kwangwoon University in Korea. Specialized in full-colour ultra-realistic holography, he contributed to the development of the “Ultimate” holographic emulsion. Passionate about animation movies, he invented the first 3D display technology (Holographic Zoetrope) that mixes real colour holography and stop-motion animation. His current research interests include full-colour holography, digital holography, and holographic materials.

Laser-Induced Generation of Plasmonic Nanoparticles for Optical Security Features

by Garry W. Mudd & Demosthenes C. Koutsogeorgis

Plasmonic nanostructures represent an emerging class of novel optical technologies for the anti-counterfeiting industry. The phenomenon of surface plasmon resonance, arising from the resonant interaction of light with a nanostructured surface, can provide both overt and covert effects that are governed by physics that is principally distinct to traditional optically variable devices (OVDs).

We present the development of a platform technology that utilises laser-induced generation of plasmonic nanoparticles to create optically variable effects that are controlled by localised surface plasmon resonance (LSPR) – whereby spatial manipulation of a highly-localised heating effect allows for the selective nanostructuring of thin metal films on a range of industry-compatible polymers and the production of highresolution and easily identifiable optically active features.

We discuss the potential applications, highlighting that the optical effects arising from LSPR (such as an enhanced or reduced reflectivity, transmission, or absorption) are particularly suited for transparent substrates and can be tuned to produce a highly-controllable and reproducible colour gamut. Additionally, the laser-processing method aligns well to digitallydriven requirements, by allowing for the embedding of uniquely identifying information (i.e. numbering, barcoding, etc.), as well as affording the ubiquitous benefits of laser-based manufacturing, namely; scalable, large-area and rapid processing.

Use of Holographic Nanotechnologies for Protection Against Counterfeiting and Copying of Digital Goods Identification Codes

by Leonid Tanin

The Republic of Belarus has accumulated significant experience in the field of goods marking. The control identification marks used for marking more than two dozen product groups are protected by the product of holographic nanotechnology “know-how” – a crystallogram (a hologram, additionally containing a latent polarization image). The authors of the patent for this unique product – control identification mark with combined protection, which has no analogs in the post-Soviet space, are such Belarusian enterprises as CJSC “Holographic Industry”, the Republican Scientific and Technical Enterprise “Cryptotech” of the Committee of State Signs under the Ministry of Finance of the Republic of Belarus, the State Scientific Institution BI Stepanov Institute of Physics of the National Academy of Sciences of Belarus and others. Control identification marks with crystallograms are produced by Republican Unitary Enterprise “Minsk Printing Factory” of Goznak under a license agreement with Belarusian copyright holders. The production and later use of such control identification marks are carried out in the regime provided for the forms of strict reporting.

It seems to us reasonably that the addition of two-dimensional bar codes with crystallograms will fundamentally suppress wholesale resale of counterfeit (falsified) goods, their illegal retail sales and will ensure the maintenance of legal trade during periods of failure of national systems of traceability of goods or a unified register of identification means of the Eurasian Economic Union as a result of hacker attacks.

It remains to express the hope that the Belarusian experience in the use of protective crystallograms will be evaluated and widely used.
