Molecular matrix printing technology relies on the energization of suitable leuco dyes to form discernable marks on paper. In practice, the paper can be impregnated with a dye combination prior to printing, or it can be added during the printing operation itself. Because this technology is a surface phenomenon, double-sided printing is possible. As shown in the figure, a write head 2 and wetting mechanism 4 are positioned on one side of the paper 6 which is to be printed upon. A platen 8 is placed on the other side of the paper 6 opposite the write head 2. Another write head 2', wetting mechanism 4' and platen 8' combination is placed in the print path to effect almost simultaneous printing on the other side of the paper 6.
