Abstract
A reproduction method and apparatus provides for the secure reproduction of confidential documents that include a machine readable code or indicia that is preferably invisible. The reproductions are also provided with a machine readable code to provide security against the making of reproductions from copies from originals. The method and apparatus of the invention comprises a multicolor development station reproduction apparatus wherein one or more color development stations are employed to reproduce the visual portions of the original document. The invisible encoded portions of the document are electronically 'read' from the original and reproduced in the same reproduction apparatus with a developer station having transparent toner particles incorporating an ultraviolet fluorescent ink or composition.
