1. A system for high-speed marking of a fiber-based product, comprising:
a plurality of radially oriented heat stamp assemblies, each including a heating element thermally coupled to a stamping block, a temperature sensor thermally coupled to the stamping block, and a platen bearing an embossed pattern;
a controller configured to heat the stamping element to a predetermined temperature via the heating element and information acquired from the temperature sensor; and
rotatably bring the embossed patterns of the heat stamp assemblies adjacent to, but not in contact with, the fiber-based product to thereby produce a charred region corresponding to the embossed pattern.
