  • Patent number: 9156529
    Abstract: A method of making a lithographic printing plate including the steps of a) image-wise exposing a lithographic printing plate precursor including a light or heat sensitive coating on a support having a hydrophilic surface or which is provided with a hydrophilic layer, and b) processing the precursor consecutively with a first solution and a second solution thereby removing the coating from the support in the non-printing areas. The first and second solutions are provided by a cascade system such that the second solution overflows into the first solution and the first solution overflows into a container to be further 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 30 ml/m2 of treated precursor.
