A method of making a lithographic printing plate comprising the steps of: a) providing a lithographic printing plate precursor comprising (i) a support having a hydrophilic surface or which is provided with a hydrophilic layer, (ii) a photopolymerizable coating on said support, b) image-wise exposing said coating in a plate setter, c) developing the precursor, thereby removing the non-exposed areas of the coating from the support, whereby the developing step is carried out off-press in a gumming unit by treating the coating of the precursor with a gum solution.
