Abstract: An improved system and method for tracking and managing documents in a high throughput document printing line comprising a printing means, a sensor means and a processing means. The printing means prints a desired invisible symbology and visible text on a document fed to it. The clear printing toner is fused with an invisible marker. The invisible symbology is printed on the document using the invisible marker. The sensor means is capable of reading the invisible symbology printed on the document. The sensor means communicates the sensor readings to a processing means. The processing means receives the sensor readings from the sensor means and correlates the sensor readings with data identifying a plurality of projects thereby determining the appropriate project to which the printed document belongs.
