There is disclosed a method of producing a lithographic printing plate which comprises a light sensitive coating applied to an aluminium substrate, in which the method includes an anodising step in which the aluminium substrate is anodised using phosphoric acid present in a range from 100 % to 30 % by volume and sulphuric acid present in a range from 0 % to 70 % by volume of the same normality, and a coating step in which the anodised aluminium substrate is coated with a resin which comprises a photo crosslinkable polymer having a maleimidic functional group plus a sensitiser. The invention therefore provides good adhesion of the coating and improved sensitivity. |
