    Abstract: A method of making a lithographic printing plate includes the steps of a) image-wise exposing a lithographic printing plate precursor, including a support including a hydrophilic surface or a hydrophilic layer and, thereon, a light or heat sensitive coating including a photopolymerizable composition, b) processing the precursor, consecutively, with a first solution and a second solution, to remove the coating from the support in the non-printing areas, wherein the first and second solutions are provided by a cascade system, the second solution overflows into the first solution and the first solution overflows into a container to be treated as waste, and the second solution is regenerated by adding a replenishing solution or a mixture of replenishing solutions at a rate of at least 5 ml/m2 of treated precursor and at most 100 ml/m2 of treated precursor.

    Abstract: A negative-working lithographic printing plate precursor includes a support and a coating containing a photopolymerizable layer including a polymerizable compound including: a free radical polymerizable group, and at least one moiety having a structure according to Formula (I): wherein n represents an integer equal to 0 or 1; L1 represents a divalent linking group; and * denotes the linking positions to the rest of the structure, with the proviso that the carbonyl groups in Formula (I) are bonded to a carbon atom.
