Industrial application of Lasers in the graphic industry is undoubtedly increasing. Examples are typesetting, colour separation and laser dot generating, laser printing, laser gravure, laser plate making, etc. Application of laser technology in the area of security printers had a rather slow start but is speeding up rapidly. Encoding credit cards by laser and holography are examples of the application of lasers in this field. In this paper we shall shortly summarize the known industrial applications of lasers in the graphic industries and report about the applications of lasers in the detection of a coded watermark. A step and repeat holographic laser camera for the production of holograms in dichromatic gelatine will be described.
