Abstract

Resistive ribbon thermal transfer is a printing technology in which strokes are formed by passing an electrical current from a small probe (typically 1.5-mil diameter) through a layered ribbon structure consisting of a relatively thick resistive layer for generating local heating and a thin conductive layer for returning the electrical current to ground. The local heat produced by the current pulse is either used to alter the optical properties of plastics for printing on transparencies, or is used to transfer ink from an inked version of the ribbon structure to paper.
