摘要： The technology encompassed by the practice of this invention includes apparatus for ink jet printing under the control of electronic circuitry and ink jet printing under the control of an operator, for example, a typewriter. Broadly, the technology presented in accordance with the principles of this invention utilizes an ink eradicator which removes indicia of the ink by chemical reaction. The character of the eradicator fluid is such that another fluid may be utilized either together therewith or separately to neutralize the residue from the chemical reaction so that printing can readily be accomplished in the location where erasure has occurred. Specifically, practice of this invention is contemplated with means that applies the eradicator fluid over the location on a surface where printing has occurred by ink jet droplets as well as over an entire area thereon within which there is ink jet printing for which a change is to be achieved. For exemplary embodiments of this invention, the eradicator fluid is applied by a wick from a reservoir and the chemical reaction is enhanced by heating the location for the erasure by an external heating means.

摘要： A method is described for selectively reinking a resistive ribbon thermal transfer printing ribbon, comprising:(1) positioning a used resistive ribbon thermal transfer printing ribbon in a colloidal dispersion of electrophoretically depositable ink prepared(a) heating a water-insoluble polymeric binder having a melting point in the range of 85.degree. C. to 100.degree. C. until the polymeric binder has been melted to a liquid state,(b) adding and blending a pigment into the melted polymeric binder,(c) adding and blending a heated dilute, aqueous solution of a carboxylic acid to the composition formed in (b), and(d) adding and blending a colloid charge-forming compound to the composition formed in (c), to form an aqueous dispersion of a pigment-containing polymeric colloid,(e) cooling the dispersion formed in (d); and(2) passing an electric current through said colloidal dispersion, with an electrically conductive layer of said ribbon serving as one electrode, to electrophoretically deposit the pigment-containing polymeric colloid on areas of said ribbon that have been depleted of ink, to form a ink layer of uniform thickness.
