ABSTRACT:
Embossing a web between unmatched male and female embossing elements, wherein the sidewall slope of the female element is different than the sidewall slope of the male element, provides an embossed web having markedly improved embossing pattern definition and, in the case of roll products, greater roll bulk at equivalent roll firmness. The unmatched male and female embossing elements are preferably made by laser engraving rubber embossing rolls.
