FIELD: printing.
SUBSTANCE: invention relates to a method for the manufacture of protected paper, including a step consisting in the manufacture of a watermark using a mask (10) attached to the paper machine wire, with the mask containing a rack of elements (18) to form light zones on the watermark, connected by binding elements (15), in this case, the specified light zones are arranged as pixels of the raster image, while the specified binding elements are thin enough that at least certain specified elements (18) for forming light zones provide the formation of pixels of the raster image, which, when viewed with the naked eye in transmitted light, would look like isolated pixels.
