Abstract
A method for making a lithographic printing plate includes the steps of: (1) providing a heat-sensitive lithographic printing plate precursor including on a support having a hydrophilic surface or which is provided with a hydrophilic layer, a heat-sensitive coating, (2) image-wise exposing the precursor with IR-radiation or heat, and (3) developing the image-wise exposed precursor with an alkaline developing solution including a compound having at least two onium groups. According to the above method, a printing plate is formed with an improved developing latitude or an improved exposure latitude.
