Abstract
Systems and methods of embossing flat pieces (such as thin cards and similar materials) that prevent the embossed pieces from sticking to each other during subsequent handling. In some embodiments, pieces are manufactured in rows and columns on a large sheet, with (typically) the distance between text embossed on adjacent rows and (particularly) the distance between texts embossed on cards from adjacent columns being constant. Cards that will be stacked immediately adjacent each other after the cards are cut from the large sheet have text embossed on them that varies, so that the cards cannot tightly nest against each other and stick together.
