Abstract
Imaging elements for dual-sided direct thermal printing are described, generally comprising a substrate and a thermally sensitive coating on each side. Calendering is provided to produce a smoothness of 75 Bekk or greater on each side of the media product. A subcoat or base coat, e.g., of calcium carbonate or clay, may be provided on paper substrates to enhance smoothness of finish and the quality of thermal printing.
