Abstract
A method for the preparation of a negative working lithographic printing plate is disclosed. A printing plate precursor comprising a lithographic support and an image forming layer is mounted on a printing press. A liquid containing a dissolution inhibitor is image-wise dispensed on the precursor by means of ink jet printing. The precursor is developed on press by the application of fountain and ink whereby the image areas are retained and the non-image areas are removed.
