Abstract: The invention relates to a method of making a lithographic printing plate comprising the steps of providing a photopolymer printing plate precursor that is photopolymerizable upon absorption of light in the wavelength range from 300 to 700 nm, exposing said printing plate precursor with light in the range from 300 to 700 nm and processing said exposed precursor with an aqueous alkaline developer, characterized in that the alkaline developer comprises a polyethyleneoxide/polypropyleneoxide surfactant having a specific composition. The method leads to less depositions in the developing apparatus and on the processed printing plates and the developer used has an increased sedimentation stability.
