Diffractive Features on Banknotes Special Report

24 August 2018

The IHMA has secured an 80% discount on the latest special report ‘Diffractive Features on Banknotes’ published by Reconnaissance International. The special report will be officially launched at the African Currency Forum, which takes place in Zimbabwe from 2-5 September.

2017 marked the 70th anniversary of the invention of the hologram, while 2018 is the 30th anniversary of the first use of a diffractive optically variable image device (or DOVID) on a banknote. Since then, it has evolved to become one of the most enduring and successful public security features for currency, in use by over half of the world’s issuing authorities on one or more of their banknotes.

 

The report does not attempt to be a deeply technical or scientific document – its main purpose is to provide readers who have a non-technical background with a degree of familiarity with some of the history, technology, material science, terms, developments, latest products, market trends and other relevant factors that have led to the substantial use of DOVIDs as a banknote security feature.

In 60 pages, this report will cover the evolution of the technology over 30 years. Specifically, the benefits of DOVIDs is discussed, together with dedicated sections on origination technologies (off-axis laser interferometry, electron beam, other direct write methods and volume hologram origination), manufacturing processes and materials and the application of DOVIDs onto banknotes.

The design and integration of DOVIDs within the whole banknote design rather than simply as standalone features is also outlined, indicating the continuing confidence by central banks, printers and specifiers in DOVIDs as both a security and as an aesthetic feature.

The penultimate chapter looks at the trends of DOVIDs on banknotes and addresses the number of countries and banknotes that incorporate DOVIDs, polymer and composite substrates, windows in paper, the choice of substrate and whether it is a determining factor to use DOVIDS, plus the choice of DOVID format such as patch, stripe or thread and geographic trends.

The final chapter examines the future of DOVIDs on banknotes and discusses some of the alternative technologies that have recently come to market and their impact.

The aim of the publication is to help everyone involved in banknote design, production, issuance and security to put the use of such features into perspective and to help them approach the use of this important security feature as a vital tool in helping to prevent counterfeiting, gain public recognition and acceptance and engender pride in banknotes.

Some of the facts and figures will be covered in the September issue of Holography News.

In the meantime, the report is priced at £750, but Holography News subscribers qualify for a 50% discount, while IHMA members can obtain a copy for £150. To pre-order your copy, visit http://www.reconnaissance.net/holography-news/publications/diffractive-features-on-banknotes/
