Abstract
The use of laser technology for application of security features into security documents is introduced and specifically the security features which are applied directly into the security documents itself are covered. This innovative way of working creates effective deterrents to counterfeit and forgery. Laser applied security features become an integral part of the documents and its characteristics are unique and well-distinguishable. Together with the high levels of fineness and accuracy which can be achieved, this makes laser applied security features virtually impossible to reproduce with other means. Furthermore lasers can create first line security features which the public can easily verify with the naked eye. An introduction into laser technology gives better insight into the use of lasers in security documents. The laser offers high flexibility as the security features are created one by one under control of computer programs. As result a laser system can produce unique and personalised security features which can be applied automatically during one of the last production stages of the document. Laser applied security features are at this moment used on banknotes, passports and cheques. Examples of such applications will be shown. Also new types of laser applied security features will be introduced.
