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 coating on said support, comprising a photopolymerizable layer, and, optionally, an intermediate layer between the photopolymerizable layer and the support,
b) image-wise exposing said coating in a plate setter,
c) optionally, heating the precursor in a preheating unit,
d) developing the precursor off-press in a gumming unit by treating the coating of the precursor with a gum solution, thereby removing the non-exposed areas of the coating from the support,
whereby said coating further comprises a compound capable of interacting with the support, said compound being present in said photopolymerizable layer and/or in said intermediate layer.
