Jura is an Austrian-Hungarian company providing security printers with proprietary security printing design software, complete security printing pre=press systems (HW + SW), ultrahigh resolution image setters developed for security printing market, security features, developed by Jura for security printing in general, proprietary security features, destined for document personalization systems. In addition to supply such products Jura is providing its customers with full technical support, as integration, installation, training, hot-line remote and/or on-site support, service and maintenance worldwide. Research and development have always been in the focus of Jura's activity. Development and testing of new software, new security features are the most important parts of the work. Jura was the first on the world to release her Engraver Software enabling artist-engravers to create engraving-styled portraits digitally. This development, incompatibility with Jura's security design software package, enabled a full digital workflow for banknote origination. Jura made a lot of remarkable steps to develop security features also for Document Personalization. This development links the personal data with the photography of the document' holder by encoding personal data to the photography, invisibly for naked human eye, however, decodable by an appropriate decoding device. This feature exists also in machine-readable digital version. Experts of Jura started the research and development on digital screening 15 years ago for commercial printing and 10 years ago on special screens for security printing technologies. In very early stage of this development, when knowledge of creating each screen-dot individually in shape, form and position was acquired, the idea was born to use the screen dots as secondary data holder for encoded messages.
