Properly selected and secured substrate is the base for well secured banknotes. PWPW belongs to the exclusive group of a dozen or so companies in the world with competences and proper technical equipment to print banknotes on all currently used substrates – natural (cotton), semi-synthetic, composite and polymer.
At its own paper mill, PWPW produces among others: classic, cotton paper (Fortis™ ), Fortis™ Composite paper, comprised of natural and synthetic fibres and Fortis™ Pro paper with additional anti-soiling coating.
Another method of enhancing durability of circulating banknotes is coating them with a layer of special varnish in the flexography printing process.
PWPW also produces and offers varnishes. PWPW experts will be pleased to help in substrate selection, taking into account both environmental conditions and economic issues.
THE ‘POLISH BISONS’ PROJECT
The Polish Security Printing Works is pleased to present „Polish Bisons” project. It is our response to the requirements of customers from around the world. It presents the banknote substrates’ technological portfolio.
The aim of preparing a series of test banknotes was to illustrate how the choice of substrate impacts the performance of banknotes in circulation. Factors influencing substrate selection include among other: climate conditions and the manner of using and storing banknotes.
The same banknote design was printed on various substrates in many technological options to objectlively demonstrate the differences (each substrate type has a different serie’s symbol).
