PolySecure®: Engineering for Dimensional Precision and Print Registration

Banknote substrate must do more than provide a printable surface. During production, security features, windows and printed elements must remain accurately aligned through multiple downstream printing processes.

For polymer banknotes, dimensional control of the substrate therefore plays an important role in maintaining registration consistency throughout production.

Q&T has developed PolySecure® with a focus on dimensional precision, manufacturing consistency and compatibility with security-printing processes.

Why Dimensional Precision Matters

A banknote passes through multiple printing and finishing stages before entering circulation.

During these processes, printed elements and security features need to remain correctly positioned relative to one another. Changes in substrate dimensions can make this alignment more difficult to control.

Maintaining dimensional precision helps security printers preserve registration between the substrate, security features and subsequent printing processes.

PolySecure® Technical Qualification

Technical qualification work on PolySecure® has examined the registration of security features against defined production tolerances.

The results demonstrated controlled security-feature registration within the qualification conditions, supporting Q&T's engineering focus on substrate precision and manufacturing consistency.

Registration Through Banknote Production

Registration becomes particularly important when substrate features must align with printing applied later in the production sequence.

Offset, intaglio and other downstream processes can depend on stable positioning between the substrate and the printed design.

Consistent substrate dimensions can therefore support production control by helping security printers maintain alignment as the banknote moves through successive manufacturing stages.

From Precision to Production Consistency

Dimensional precision is not an isolated substrate property. It influences how consistently the material can move through subsequent banknote production processes.

Controlled registration can reduce the need for corrective press adjustments and support more stable interaction between the substrate, security features and printed elements.

For Q&T, dimensional control is therefore treated as part of the broader engineering of PolySecure® rather than as a standalone specification.

Engineering the Substrate as a System

PolySecure® is developed as a banknote substrate platform in which material properties, dimensional control, print compatibility and security-feature integration must work together.

Q&T continues to use technical qualification and production evaluation to develop the platform for the requirements of modern banknote manufacturing.

Dimensional precision and registration control form one part of that wider engineering approach.
