Abstract
A system and a method for converting markings made on media with a marking agent into a digital form representing the markings. The system of the present invention includes a marking device and an illumination digital scanning device. The marking device can be a manual or machine marking device, each containing the marking agent. The marking agent is dispensed by the marking device onto the media. The marking agent is a chemical that emits a certain radiation frequency set when illuminated by an illumination frequency set. The illumination digital scanning device converts the markings of the marking agent into a digital form. The method of the present invention includes marking the media with the marking agent, illuminating the markings to cause the marking agent to radiate at the radiation frequency set and converting the radiation into a digital form representing the markings.
