A process for manufacturing a non-woven fabric having on its surface distributed elements having a physical dimension, comprises screen printing on wet fabric a desired shape using a paste that expands under heating by virtue of a puffing agent contained therein. L'invention concerne un procédé de fabrication d'un nontissé dont la surface présente des éléments distribués à dimension physique. Le procédé consiste à imprimer par sérigraphie une forme désirée sur un tissu humide, à l'aide d'une pâte qui se dilate au chauffage du fait d'un agent gonflant présent dans la pâte.
