Abstract:
A method for making a lithographic printing plate includes the steps of (i) providing a lithographic printing plate precursor including a coating, the coating including an image-recording layer which includes hydrophobic thermoplastic polymer particles, a binder, and an infrared absorbing dye, wherein the hydrophobic thermoplastic polymer particles have an average particle diameter, measured by Photon Correlation Spectroscopy, of more than 10 nm and less than 40 nm, and the amount of the IR-dye, without taking into account an optional counter ion, is more than 0.70 mg per m2 of the total surface of the thermoplastic polymer particles, measured by Hydrodynamic Fractionation, and the amount of hydrophobic thermoplastic polymer particles relative to the total weight of the ingredients of the imaging layer is at least 60%; (ii) exposing the precursor to infrared light; and (iii) developing the exposed precursor in an alkaline aqueous solution.
