ABSTRACT:
A method is presented for preparing a lithographic printing plate by an ink jet process of discharging dropwise an oil-based ink using electrostatic attraction onto a lithographic printing plate precursor to form an image. The lithographic printing plate precursor has a water-resistant support having provided thereon an image-receiving layer having a lithographically printable hydrophilic surface for forming the image. The water-resistant support has a specific electric resistance of 10.sup.10 .OMEGA.cm or less in an area directly under the image-receiving layer. The oil-based ink is composed of positively or negatively charged electroscopic resin particles dispersed in a nonaqueous carrier liquid having an electric resistance of 10.sup.9 .OMEGA.cm or more and a dielectric constant of 3.5 or less. The resin particles are copolymer resin particles obtained by polymerization granulation of a solution of a monofunctional monomer, a monofunctional macromonomer and a resin for dispersion stabilization.
