A substrate, such as a core of multiple phenolformaldehyde impregnated paper sheets, is coated with a layer of a thermosetting resin, such as melamine-formaldehyde, having a printed design on its undersurface. The substrate is coated by applying the themosetting resin to a release sheet, printing a design on the resin surface, positioning the coated release sheet over the substrate, hot-pressing the resin to the substrate, and stripping off the release sheet.
