Abstract: In the system of the present invention the ink used is a low concentration aqueous solution of a compound that forms a visible percipitate with a metal ion. The compound and the cooperating ion are selected to produce the desired precipitate color and for greater convenience is selected to react at room temperature. The metal ion is imparted to the printing surface either by inclusion during the manufacture of the paper stock or by treating the paper surface at some subsequent time including during the printing cycle prior to the printing operation.

Abstract: LE9-80-029 LAMINATED ELEMENT, THERMAL PRINTER AND PROCESS FOR LIFT-OFF CORRECTION A ribbon (22) in thermal printing has an outer layer (50) which adheres to printed characters at somewhat elevated temperatures but is non-tacky at room temperatures. The embodiment has an active layer of an ethylene vinyl acetate copolymer, an acrylic polymer, and carbon black. Thermal printing is conducted from the preferred ribbon by setting the switch (44) for heating to temperatures higher than the lift-off temperature. Lift off is accomplished by returning to the printing position of the error and setting the switch (44) for lower voltage to the printing electrodes (9). The guide (29) allows cooling so that the bond is set before the ribbon (22) is pulled away.
