Design for testability (DFT) approaches are largely adopted in electric/electronic data processing equipment design since 1940s/50s. The purpose is to increase the efficacy and efficiency of the measuring and testing activities.

Continuously increasing complexity and sophistication of banknotes requires a similar approach. Built-in capabilities and features should be included to facilitate test and control. These must be already conceived in the design phase and should be verified against the capabilities of the quality and process control tools, before entering mass production.

Expected benefits from a DFT approach to banknote design, are:

\- Reduced production set-up time, due to simplified instruction of QC tools

\- Lower investments, due to compatibility with available QC tools

\- More stable working conditions of control tools with fewer runtime adjustments

\- More reliable controls and measurements, with less false indications or rejects.

The presentation will provide provide some practical suggestions to banknote and other security documents designers, for improving testability and printing process control by means of automatic tools installed in the printing line.
