Abstract
In this paper we describe the application, design and performance of a novel, small form factor Dyson Relay lens with inbuilt illumination configured for imaging printed marks. The high resolving power of the design clearly reveals the microscopic stochastic nature of printing processes and ink/substrate interactions. These imperfections provide a hard to copy “printed mark signature” that can be used for checking authenticity.
