Paper Abstract

The increasing need for optical security systems can be perfectly illustrated by reviewing the developments in security printing. The invention of photography in the 19th century forced the production of securities to introduce colour. Colour photography was encountered by the introduction of fine line structures, etc. The hate-love relationship between security printing and optical security systems has been beneficial for both of them in the past. With the invention of lasers and the application of the laser technology in the graphic arts, a merger of security printing and optical security systems has taken place.
