摘要：The invention relates to a method for the preparation of a printing platecomprises forming an oleophilic image on a substrate for a printing plate comprising asupport having at least one hydrophilic layer on its surface, the oleophilic image beingformed by inkjet printing an aqueous solution or aqueous colloidal dispersion of ananionic oleophilising agent on the surface of the support and drying the applied solutionor dispersion, such that, on drying, the area of the surface to which the solution ordispersion was applied becomes lithographic ink-accepting, characterised in that thehydrophilic layer comprises a crosslinked cationic polymer. The invention further relatesto a substrate for a printing plate comprising a support having at least one hydrophiliclayer on its surface wherein the hydrophilic layer comprises a crosslinked cationicpolymer.
