Abstract
A print head applies electrical energy to an electrically resistive and grounded transfer ribbon bearing heat transferable dye, during sliding pressure contact and relative movement between the head and ribbon, for resistive heating of the dye to a transfer temperature for transfer to a receiver to form images of selective pixel size thereon. The head has a row of electrodes with end faces and an electrically non-conductive substrate with an end face, the end faces lying in a contact plane for contact with the ribbon. A groove in the substrate end face separates such end face from the electrode end faces. The width of the groove is sufficient to inhibit heat transfer at the groove from the ribbon to the substrate for controlling the dye amount heated to transfer temperature adjacent the groove during the relative movement and in turn the image pixel size.
