Lithographic printing plates can be prepared and made ready for lithographic printing with simple wet development or processing. A positive-working lithographic printing plate precursor is exposed to infrared radiation for example at 200 to 300 mJ/cm2. The exposed precursor can be simply processed with water or an aqueous solution, and uniformly exposed to radiation, heat, or both. The positive-working lithographic printing plate precursor has a hydrophilic aluminum substrate, a crosslinked hydrophilic inner layer, and an oleophilic surface layer that is weakly bonded to the crosslinked hydrophilic inner layer. |
