1. A process for controlling a reproduction system, comprising the steps of:

  • scanning an image to detect at least one taggant in at least one marking material forming said image; and

    issuing instructions to said reproduction system, wherein said instructions cause said reproduction system to take an action selected from the group consisting of;

    (a) prohibiting reproduction of those portions of said image formed by a said marking material containing at least one predetermined detected taggant, and reproducing of all other portions of said image;

    (b) prohibiting reproduction of any part of said image upon detection of at least one predetermined taggant;

    (c) reproducing only those portions of said image formed by a said marking material containing at least one predetermined taggant;

    (d) reproducing portions of said image formed by a said marking material containing at least one predetermined taggant in a different manner from that in which said system reproduces portions of said image formed by a said marking material not containing said at least one predetermined taggant; and

    (e) identifying a source of said image on the basis of detection of at least one predetermined taggant.
