Abstract

To protect security paper and the information contained thereon against unauthorised reproduction in a copying device, the security paper is provided with light-deflecting structures which reflect the light, applied to the document during the copying operation, into the environment at a defined angle in such a way that they occur at a point on the photoconductive drum, at which normally information is contained at another point on the security document. Due to this bloom, at least some of the information recorded on the security document is not reproduced on the copy. The copy is thus recognisable as such.
