Abstract

Optical security printing has reached a high level of sophistication as a result of intense activity in world markets within which the potential for the crook to make money by counterfeiting has reached astronomical levels. Each commercial company that involves itself in the security printing business has its own secrets which it must not divulge. A plenary talk such as this is perforce confined to discuss matters of vision, materials, optical recording and visual psychology which lie outside the specifics of individual commercial approaches. We look at new optical ideas and especially the influences of materials developments in this fascinating field of research.
