Improvements in document security - The next generation

Typically the variable data on identification documents are secured with an over laminate which is a costly and slow process. The Currency and Security Document team at Note printing Australia (NPA) has focused on securing the variable data without the need for lamination. NPAs efforts have focused on developing a unique securitised polymer film carrier combined with tamper evident smart coatings. The smart coatings are translucent which enable two way image verification and demonstrate excellent receptivity to inkjet printing for high image quality. The coatings can be imaged using a mask based laser system which creates an optical switch effect with the micro elements of the base substrate. Substantial product testing has been undertaken which shows that the integrity of the document is maintained in normal use. The paper also highlights other security feature developments which create improved levels of document security.
