| Zusammenfassung: | A method for making a lithographic printing plate comprising the steps of:
(i) providing a lithographic printing plate precursor having a support with a hydrophilic surface or which is provided with a hydrophilic layer and a coating provided thereon, the coating comprising an image-recording layer which contains thermoplastic particles;
(ii) exposing the precursor to heat or infrared radiation;
(iii) developing the exposed precursor in an alkaline aqueous solution; characterized in that the alkaline aqueous solution comprises at least 0.05 g/l of lithium ions. |
