Resistive ribbon printing with fusible inks is uniquely suitable for printing on transparent plastic films, since the print is smear free immediately on removal from the printer. This cannot be said for either impact printing (as yet) or drop-on-demand ink jet printing, since in both these printing technologies the inks are fluid and are not absorbed by the foil medium. The availability of color inks for resistive printing ribbons increases the potential utility of this technology for preparation of attractive colored transparencies. Resistive ribbon printing can be carried out with an ink layer consisting of a transparent material colored by a dye, which produces a transparent print on the plastic, transparent sheet, as is required for the preparation of foils for projection.
