The topic of land on a tablet design is a much‚Äźdebated one.

Tablet land is the narrow, horizontal surface perpendicular to the tablet’s periphery, which creates a junction between the tablet’s periphery and cup. The three primary reasons for incorporating a land into a tablet’s design are to increase the strength of the punch edges, increase the wear characteristics of the inner edge of the punch cup, and reduce the severity of nicks on punch edges.
