Security Threads for Banknotes
An essential guide to the technology behind and use of security threads for banknotes.
The first use of a security threads as we know it was in 1940. 80 years later, and the security thread has evolved to become one of the most successful and innovative features to secure banknotes – – combining high public recognition value and aesthetic appeal with machine-readability and cost efficiency.
There are currently 1,026 circulating denominations in the world (latest/current versions of notes only), of which just over 85% are printed on paper. Of these, nearly all (95%) contain at least one security thread. 20% have an embedded thread, 23% a narrow windowed thread and nearly 50% a wide windowed thread. 8.5% have more than one (eg. embedded and windowed).
The thread technology that stands out in all of this is the wide windowed thread – and in particular the range of features that this can now carry, from colour shift and diffraction to the new generation of micro-optics, micro-lenses and micro-mirrors.
The Report contains other insights and anecdotes, but it is its comprehensive coverage of all aspects of banknote threads, from cradle to grave, that make it a must for your understanding of the opportunities provided by security threads and how to use them as part of the arsenal of features to protect your banknotes.
Included in this report
In 130 lavishly-illustrated pages, the report examines the evolution of security threads for banknotes, their types, latest technology developments, material science, machine readability, security features, design, integration, trends and future opportunities, with sections on:
- History and key milestones
- Benefits and costs
- Thread types and technologies
- Materials and manufacture
