Abstract
A glosser, and method of glossing, includes a belt-type glosser in which resin-coated web or sheet material is pressed or molded against a casting surface of the belt under heat and pressure, and is thereafter removed. A matte surface is provided by forming a non-locking grooved pattern on the casting surface of the belt in the form of a diffraction grating. The grating configuration is formed with a series of lands, separated by grooves or depressions, in which the side walls of the depressions are tapered to provide a valley narrower at the bottom than at the top adjacent the land surfaces so as to be free of resin-trapping overhanging projections or portions. The spacing between the grooves may be randomized.
