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.

A method and apparatus for exposing an imaging sheet to form a latent image in a layer of photosensitive microcapsules on the surface of the imaging sheet utilizes wavelength or frequency transformation of light images representative of the latent image, which transformation is performed by a light valve. An original document, including images which are to be transferred to an imaging sheet, is illuminated by visible light which is directed upon and controls the light valve, such that actinic radiation illuminating the light valve is modulated in accordance with the visible light; the modulated actinic radiation is directed upon the imaging sheet to form a latent image therein. In this way, the original document may be illuminated by visible light which is effectively wavelength or frequency transformed by the light valve into actinic radiation, typically in the ultraviolet range.
