FIELD: printing.
SUBSTANCE: article and the valuable document are made on paper, polymeric, composite or nonwoven material and contain at least two independent and at least partially intersecting watermarks. At the intersection places of watermarks the optical density of the resultant image through-transmission is different from the optical densities of each of the initial symbols, and forms an additional visual effect.
EFFECT: increased protection level of the multilayer article and the valuable document due to creating an optical visual effect when through-transmission testing.
