摘要： A method of making a lithographic printing plate comprising the steps of: a) image-wise exposing a lithographic printing plate precursor, comprising a light or heat sensitive coating on a support having a hydrophilic surface or which is provided with a hydrophilic layer, 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 30 ml/m2 of treated precursor, wherein said first and second solutions are circulated respectively by a first and second liguid conveying system, wherein the first solution present in said first liguid 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.
摘要翻译：一种制备平版印刷版的方法，包括以下步骤：a）将平版印刷版前体成像曝光，所述平版印刷版前体在包含亲水性表面的载体上具有光或热敏涂层，或者设置有亲水层，b）用第一溶液与第二溶液一起处理所述前体，从而在非印刷区域中从载体上除去涂层，其中所述第一和第二溶液由级联系统提供，其中所述第二溶液溢出到所述第一溶液中并且所述第一溶液溢出到容器中以进一步作为废物处理，其中所述第二溶液通过以至少5ml / m 2经处理的前体和至多30ml的速率加入补充溶液或补充溶液的混合物来再生 / m 2的处理前体，其中所述第一和第二溶液分别通过第一和第二液体输送系统循环，其中第一和第二溶液存在于所述第一液体输送系统中的溶液具有分别由式1和式2定义的至少Vmin至多Vmax的体积，Vmin = [A +（加工宽度/0.95μm）]。升（公式1）Vmax = [B +（处理宽度/0.95μm）]。（式2）其中Vmin和Vmax分别表示在所述第一液体输送系统中存在的最小和最大体积，它们各自以升计，其中A和B分别表示2和15的常数值，并且其中所述处理宽度表示处理单元内垂直于处理方向的以m表示的宽度，其可用于以均匀方式跨过其宽度处理板前体。
