High sheet count rolls of spot-embossed, soft bathroom tissue suffer from embossing patterns becoming pressed out by the high winding tension necessary to confine the size of the roll to a diameter of about 5 inches. This size is necessary in order for such high sheet count rolls to fit within the bathroom tissue dispensers found in most households. However, by embossing the tissue between a resilient back-up roll and an engraved embossing roll having short male embossing element heights of only from about 0.005 to about 0.035 inch, the tissue sheet becomes simultaneously calendered, which lowers the sheet caliper (as measured under a compressive load). Because of the resulting lower caliper, the embossed sheet can be wound into the required roll size with less tension on the sheet, such that the embossing pattern for tissue sheets within the roll remains well defined.
