Patent ID: 7121204

Claim:
A method of printing comprising the steps of (i) providing a lithographic printing plate precursor comprising a support and a heat- or light-sensitive coating; (ii) image-wise exposing the coating to heat or light; (iii) prior to step (ii) or (iv), mounting the lithographic printing plate precursor in a printing unit of a printing press, said printing unit comprising a plate cylinder onto which the precursor is mounted, an inking system adjacent the plate cylinder and a processing liquid system adjacent the plate cylinder comprising one or more rollers for supplying a processing liquid onto the coating while the lithographic printing plate precursor is mounted on the plate cylinder; (iv) developing the printing plate precursor while the plate precursor is mounted on the plate cylinder by supplying processing liquid to the precursor coating by means of the one or more rollers, thereby obtaining a lithographic printing plate; and (v) printing by supplying single-fluid ink to the lithographic printing plate by means of the inking system, wherein the inking system is adjacent the plate cylinder during at least step (iv).
