    Abstract: A method for making a lithographic printing plate comprising the steps of:
    - providing a lithographic printing plate precursor comprising a heat sensitive image-recording layer, said image-recording layer comprising hydrophobic thermoplastic particles;
    - image-wise exposing the precursor to infrared radiation having an energy density of 190 mJ/cm 2 or less;
    - mounting the exposed precursor on a printing press;
    - developing the mounted precursor by supplying ink and/or fountain; and,
    - baking the plate by keeping the plate at a temperature above the glass transition temperature of the thermoplastic particles during a period between 5 seconds and 2 minutes.
