Abstract

The invention concerns an uncoated paper comprising at least a mark resembling a watermark, characterised in that one or several specific zones of the paper has a reduced thickness with respect to the rest of the paper, the mass per unit area in said zone(s) of the paper being identical to that of the rest of the paper. The invention also concerns a method for making uncoated paper comprising at least a mark resembling a watermark characterised in that it consists of producing said mark after the paper-drying step, by the following steps which consist in: a) applying a wetting solution on at least one face of the uncoated paper; then b) applying pressure and heat in said zone(s) so as to evaporate said solution and densify the non-coated paper in said zone(s) with respect to the rest of the paper.
