Erwin Wagner explores what makes security printing so different from conventional printing and looks at recent innovations in machines, ink, substrates and digital systems designed to protect against counterfeiting threats.
The ongoing challenge in the world of security print is to continually innovate by developing techniques for producing currency, passports, tax stamps and other secure documents that thwart increasingly sophisticated counterfeiters with the technology at their fingertips to easily reproduce them. Ever-advancing development has led to state-of-the-art, optically variable devices and inks, fibres, threads, taggants, micro and nanotechnologies… and the next big thing that breaks the boundaries of printing, processing and finishing equipment.
