Abstract: A corona generating apparatus is provided comprising a back-up plate and screen wires, at least one corona discharge wire positioned therebetween, adapted to be mounted in closely spaced relation with an electrostatographic plate to uniformly apply an electrostatic charge onto said plate, a corona-generating potential source connected to said corona discharge wire adapted to generate a corona discharge from said corona wire, and a second potential source adapted to be connected to said screen wires and impress a time or position varying voltage upon said screen wires permitting high initial charging current to flow thereby rapidly charging said plate while limiting the ultimate charge applied thereto.

Abstract: An apparatus 30 for ink-jet printing on a recording medium 34 is provided which includes the steps of jetting aqueous ink drops 40 on the recording medium 34 (paper) in the form of an image. The aqueous ink used is a slow-drying (high-surface tension) ink 20 which does not penetrate the paper/paper fibers 34 for a relatively long time. Prior to penetration of the paper/paper fibers 34, the water in the droplet is quickly evaporated from the ink while still resident on the paper surface. The evaporation process is substantially completed prior to an additional liquid ink 20 being jetted 40 onto the same or adjoining location of the recording medium. The evaporation is rapid enough to prevent the resident ink from substantially migrating/wicking to any adjacent location or into the recording medium. Further drying energy (52, 54) is transferred to the resident ink spots from the same direction as the printheads ensuring less energy requirement.

Abstract: PROBLEM TO BE SOLVED: To prevent an optical density of printed matters from decreasing and prevent papers from being seen through too much when seen from a non print side which is caused by letting a quick drying ink permeate into papers. SOLUTION: An apparatus 30 for executing ink jet printing to a recording medium 34 is provided. The recording includes printing heads 40, 42, 44 and 46 for emitting aqueous ink liquid drops in the shape of images onto the recording medium 34 (paper). Aqueous ink to be used is a slow drying (high surface tension) ink which will not permeate in the paper/paper fiber 34 for a relatively long time. Moisture in the liquid drops are rapidly evaporated by dryers 52 and 54 while the ink is present at a surface of the paper before permeating into the paper/paper fiber 34.
