摘要:
A method for making a lithographic printing plate is disclosed which comprises the steps of:
(1) providing a heat-sensitive lithographic printing plate precursor comprising on a support having a hydrophilic surface or which is provided with a hydrophilic layer, a heat-sensitive coating,
(2) image-wise exposing said precursor with IR-radiation or heat, and
(3) developing said image-wise exposed precursor with an alkaline developing solution comprising 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.
