Abstract
A method for producing a plate or sheet useful in planographic printing which is characterized in that the surface of an oleophilic body comprising oleophilic resin is subjected to a corona discharge treatment to form a hydrophilic layer on said surface, and that said method can be carried out without difficulty at a low cost and the reproducibility of the printing plate thereby produced is excellent.
