Abstract (en)
[origin: EP2116385A1] The paper (1) comprises an imprinted marking (2), which is invisible for the human eye and is visible on a copy of the paper produced on a photocopying apparatus, and a water-mark (5). The marking is imprinted on both sides of the paper by raster points (3). An area (4) surrounding the marking is printed on with raster points that is smaller than the raster points of the marking. The entire paper is printed on one side with raster points. The ratio of the raster point size to the distance between two raster points is identical. The both raster points have same optical brightness.
