<p num="1"><br/><br/> ABSTRACT OF THE DISCLOSURE<br/><br/><br/><br/><br/> An improved technique and apparatus for color-on-<br/>demand resistive ribbon printing is provided in<br/>which selected colored ink layers are transferred<br/>to a resistive printing ribbon from a color-bearing<br/>ribbon, prior to resistive ribbon printing. The<br/>color ribbon and the resistive printing ribbon both<br/>contain ink layers, the only difference being that<br/>the ink layer in the printing ribbon is preferrably<br/>uncolored. When the ink layers on the two ribbons<br/>are brought into contact with one another and<br/>heated, the ink layers will become tacky and will<br/>adhere to one another. The temperatures of these<br/>ink layers are then reduced and the printing ribbon<br/>and the color ribbon are separated from one another<br/>to cause the colored ink layer on the color ribbon<br/>to separate from that ribbon and adhere to the<br/>printing ribbon, thus causing a transfer of the<br/>colored ink layer to the printing ribbon. After<br/>this, the resistive printing ribbon can be used to<br/>print colors.<br/><br/> |
