The method comprises the steps of pressing an embossable sheet material between a complimentary tools and radiantly heating the sheet material using radiant energy from a radiant energy source. One tool is relatively-radiantly-transparent, and another tool and/or the sheet material is relatively-radiantly-absorptive.
