摘要： A method of producing a high resolution image on a substrate using an electrostatic printer by providing an electrostatic printer having a plurality of toner fountains and a set of color toners, the set having at least one reduced density toner having a color density less than that of a standard toner of the same color; and applying the reduced density toner in at least two passes of a substrate through the electrostatic printer to develop a desired image for that color. With the method of the invention, at least two toners of the same color, but different color density, may be provided to one toner fountain, thereby allowing the toner fountain to function in the manner of a plurality of toner fountains without requiring a flushing step.

摘要： A method of protecting an electrostatic image on a substrate, wherein, an electrostatic image is formed on the substrate, and protected by applying an amphipathic liquid toner on the electrostatic image by electrostatic means, and fixing the amphipathic liquid toner to form a protective layer. The amphipathic liquid toner includes a carrier fluid, an amphipathic, non-gel copolymer, and a charge control agent to provide an electrostatic charge. The carrier fluid is typically an electrically resistive hydrocarbon solvent, having an electrical resistivity of at least about 10.sup.9 ohm.cndot.cm, a dielectric constant of less than about 3, and a boiling point from about 68.degree. C. to about 250.degree. C. The amphipathic, non-gel copolymer, which is insoluble as a whole in the carrier fluid, has at least one polymer segment that is soluble in the carrier fluid and at least one polymer segment that is insoluble in the carrier fluid. The soluble polymer segment includes at least one monomer of an alkyl acrylate or alkyl methacrylate and, optionally, at least one vinyl aromatic monomer. The insoluble polymer segment includes at least one vinyl ester monomer or at least one vinyl ester monomer and at least one acrylic acid or methacrylic acid monomer.
