Banknote Durability: The ENDURANCE™ Banknote Concept
CRANE CURRENCY manufactures the most durable banknote paper in the world. Durability is part of our company’s heritage and each year around 20 billion banknotes are issued into circulation on our durable papers. Upon these solid foundations CRANE CURRENCY has launched an engineered approach to durability in the form of ENDURANCEä, a complete banknote production concept.
The ENDURANCE™ banknote is engineered from the four interconnected elements of banknote security.
1 Mechanical Strength - from the durable fiber core
2
Anti Soil Treatment (AST™) - that saturates as well as coats the fiber surface
3
Intaglio Printing - to seal the surface and drive ink into the fiber layer
4
Protective Varnishing - that bonds to both ink and the saturated fiber surface
1. Mechanical strength
ENDURANCEä starts at the durable fiber core that delivers mechanical strength and improves resistance to folding and tearing. The fibers interact in a fashion similar to engineered durable composites, dissipating mechanical stresses and protecting the physical integrity of the banknote.
2. Anti Soil Treatment (AST™)
Durability is further enhanced through polymer saturation of the paper with our Anti Soiling Treatment (AST™). During the paper-making process the anti-soil treatment penetrates deeply into the fiber matrix rather than just sitting on the paper surface. As the protection agent reaches deep inside the fiber matrix it enhances fiber bonding making the paper structurally stronger.
3. Intaglio Printing
During the printing process intaglio plays a fundamental role as it drives ink into the paper fibers, simultaneously calendaring and sealing the polymer impregnated fiber surface. By doing so the paper surface becomes less receptive to soiling and moisture.
4. Protective Varnishing
Finally, a post-print varnish treatment is applied. The varnish is formulated to have a chemical affinity for the AST™ impregnated paper. It ultimately locks down and encapsulates the ink, substrate and associated security elements within a protective shield.
The combination of the above four interconnected elements creates the ultimate protection for crucial Level 1 Public security features. We call this the ENDURANCEä banknote, engineered to endure the most demanding circulation environments.
ENDURANCE™ banknotes will enjoy:
- Dramatically increased circulation lifetime (up to twice as long as normal banknotes)
- Enhanced public and machine recognition
- Greater resistance to mechanical degradation (i.e. tears and holes)
- Less soiling and moisture absorption
- Higher levels of stiffness and physical strength favorable return on investment for central banks

CRANE CURRENCY Tumba Opens its Doors
From 11-16 May 2009 CRANE CURRENCY opened its doors to representatives from the international central banking and banknote printing community at its Tumba paper-making and printing facilities in Sweden. The event was held in parallel to the XXIIIrd Intergraf International Security Printers’ Conference which was held in the Stockholm International Fairs Center.
Visitors received an update on new banknote technology developments by CRANE CURRENCY and enjoyed a tour of the worlds most modern banknote printing facility. On a more entertaining note, many visitors made their own piece of cotton paper using the traditional techniques at the Tumba paper-making museum. The main demonstration was held at the Tumba museum, providing a unique and fascinating setting that dates back over 250 years. An interactive walk-through of all CRANE CURRENCY security thread, fiber and MOTION security features enables visitors to fully appreciate the range and diversity of banknote security technologies being developed and sold by our company.
In total we welcomed 57 visitors representing 28 different central banks and national banknote printing works. We thank them for their taking the time to visit us in May and trust they enjoyed the experience of visiting one of the worlds oldest, yet most modern banknote printing and paper-making facilities.
