DOCUMENT VERIFICATION AND TRACKING SYSTEM FOR PRINTED MATERIAL

摘要

In a multifunctional printing method and printing system, printed material is checked, verified and tracked. For that purpose different test equipments ar e located in-line with a printing line. Magnetic information being printed by a printi ng station onto the recording carrier using magnetic ink character readable toner may be in- line tested by a magnetic test equipment, which reads information from the magnetic recording zone on the carrier. Optical information may be tested by an in-line mounted optical test equipment, respectively. Further in-line test equipment is proposed such as a laser bar code scanner and an address reader. The printing line may comprise additiona l devices such as print preprocessing unwinders or print postprocessing stackers, folders or cutters.
