Abstract

A method of marking indicia on tab stock used to provide tabs for use with can ends. The method comprises providing the tab stock to a tab press comprising a punch and a die. The punch comprises a set of raised features and the die comprises a respective set of recessed features such that the features cooperate to deboss said indicia on regions of the tab stock within tab forming areas that face outwardly when the tabs are attached to a tab end. The features are such that, when the press is fully closed, the spacing between at least part of each of the raised features and at least part of each of the respective recessed features is less than the thickness of the tab stock in said regions within tab forming areas.
