Abstract: A method of making a lithographic printing plate comprising the steps of : a) image-wise exposing a lithographic printing plate precursor, comprising a support having a hydrophilic surface or which is provided with a hydrophilic layer and, thereon, a light or heat sensitive coating comprising a photopolymerisable composition, b) processing said precursor with a first solution, consecutively with a second solution, thereby removing the coating from the support in the non-printing areas, wherein said first and second solutions are provided by a cascade system, wherein said second solution overflows into said first solution and said first solution overflows into a container to be further treated as waste, wherein said 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, wherein said first and second solutions are circulated respectively by a first and second liquid conveying system, wherein the first solution present in said first liquid conveying system has a volume of at least Vmin and at most Vmax respectively defined by formula 1 and formula 2, Vmin = [A + (processing width/0.95 m) ]. liter (formula 1) Vmax = [B + (processing width/0.95 m) ].liter (formula 2) wherein Vmin and Vmax represent respectively the minimum and maximum volume present in said first liquid conveying system, each of them expressed in liter, wherein A and B represents a constant value of respectively 2 and 15, and wherein said processing width represents the width, expressed in m, inside the processing unit, perpendicular to the processing direction, which is available for processing plate precursors in a uniform way across their width.
