1. A method of applying structural elements to an absorbent article having a longitudinal direction and a transverse direction, side edges extending in the longitudinal direction and end edges extending in a transverse direction, said absorbent article comprising a topsheet and a backsheet, characterized in that a. expandable ink is applied to the top sheet, and b. the expandable ink is activated to produce three-dimensional structural elements on the topsheet. 2. The method of claim 1, wherein the expandable ink is applied to 1-50%, preferably 1-25%, of the surface area of the topsheet. The method of claim 1 or 2, wherein the expandable ink is activated by subjecting the topsheet to heat. The method of claim 3, wherein the expandable ink is activated by a means selected from infrared, hot air, microwave, or a heated embossing roller. The method according to claim 1 or 2, wherein the expandable ink is activated by UV radiation. The method of claim 1, wherein the expandable ink comprises a polymer, a solvent, and a blowing agent or expandable microspheres. The method of claim 1, wherein the expandable ink is applied as one or more liquid barriers to areas selected from the crotch region along at least a portion of the longitudinal side edges, across the front or rear region. The method of claim 7, wherein the liquid barriers are formed in the form of solid and / or dotted lines. The method according to claim 1, in which a group of dots of expandable ink is applied in the central longitudinal part of the absorbent1.
