Abstract:
1. A method for making an embossed article comprising: mechanically embossing a surface of the article; non-subjectively quantifying the mechanically embossed surface of the article with a profilometer and analysis software as the article is being mechanically embossed by determining (a) the profile of individual valley features and peak features or (b) the depth of an individual valley feature and the distance between the valley feature and an adjacent peak feature; using the quantified mechanical embossing to control the mechanical embossing depth as the article is being mechanically embossed; measuring a surface profile of the mechanically embossed article as the article is being mechanically embossed: and adjusting at least one process variable as the article is being mechanically embossed to obtain an embossed profile within a predetermined range of embossed profiles, wherein the surface profile of the article is measured prior to mechanically embossing the article and non-subjectively quantifying the mechanically embossing includes subtracting the profile measured prior to mechanically embossing the article from the profile measured after embossing as the article is being embossed.
