CCL Secure has been innovating in polymer banknote design for more than 30 years. This experience has taught us how to further optimise designs for fully integrated polymer banknotes, with collaboration being the cornerstone to producing the best results. Our presentation aims to explore three collaborative models and draws upon our experience of working with central banks directly, central bank’s own design team and commercial printers’ design team. We will illustrate our presentation with a number of case studies and examine the approach for how we can help with future projects.
