    CPC classification number: C09D11/328

    Abstract: This document discloses compositions for an ink for use in a jet printing apparatus wherein a stream of ink is forced through a small nozzle to form a series of substantially uniformly sized and spaced drops which are then sequentially charged and then deflected electrostatically for positioning the drop placement onto a record sheet.

    Abstract: INFRARED AND VISIBLE DUAL DYE JET PRINTER INK Ink formulations for jet printers having both Sulfur Black 1 and Direct Black 163 or Firect Black 19 as the dyes to provide absorbance of light in both the Visual and infrared ranges. Absorbence of infrared facilitates optical character recognition by conventional photoeonductors.

    Abstract: DRIVE FOR THERMAL PRINTING LIFT-OFF CORRECTION Ribbon (22) in thermal printing has an outer layer which adheres to printed characters at intermediate temperatures, lower than printing temperatures. The printhead (7) has a column of electrodes (9) which sweep across the character area. Lift-off is accomplished by the pattern control (40) controlling the current source (38) to provide rapid, square wave pulses displaced in phase 180 degrees at adjoining electrodes (9). The high level of the pulses is about that of the level at printing, and the pulses are sufficiently rapid so that their net effect is to raise the outer layer ribbon (22) to the intermediate temperature. At areas corresponding to underlines of characters, duration of the up period is longer. Good, long term reliability is achieved by the significant erase level being very close to the print level.
