    摘要: A media for restricting the copying of a color-reversal document utilizing one or more microdots that are embedded in the color-reversal document for providing a non-visual, but machine detectable signal. By detecting the presence of one or more microdots in the color-reversal document, a copy machine is controllably prevented from copying the color-reversal document.

    摘要: A reproduction apparatus (14) for reproducing documents (12) which comprise a base material. The apparatus comprises a platen (10) for forming a scanning area and for positioning the documents (12) on its one side, scanning means (18) for scanning the scanning area, and means for obtaining a relative movement between the scanning means and the documents in order to allow for the scanning. The scanning means (18) comprise a microwave system which is constituted by microwave transceivers (26) arranged in an array such that they can detect the presence of particles (13) which have electromagnetic properties which are substantially different from the electromagnetic properties of the base material and which are incorporated in at least a part of the documents (12), irrespective of the position of the documents (12) on the scanning area.
