Method of developing a heat-sensitive lithographic printing plate precursor with a gum solution
Abstract:
A method of making a lithographic printing plate includes the steps of: providing a lithographic printing plate precursor including (i) a support having a hydrophilic surface or which is provided with a hydrophilic layer and (ii) a coating provided thereon which includes hydrophobic thermoplastic polymer particles; exposing the coating to heat, thereby inducing coalescence of the thermoplastic polymer particles at exposed areas of the coating; and developing the precursor by applying a gum solution to the coating, thereby removing non-exposed areas of the coating from the support. According to the above method, the plate precursor can be developed and gummed in a single step.
