A method of printing employing a printing plate prepared from a printing plate precursor comprising a layer A capable of being removed by water or both water and ink on a printing press comprises the steps of imagewise exposing the precursor, mounting the precursor on a plate cylinder of the printing press to fix the precursor at a fixing section on the plate cylinder, providing a water repellent area in the layer A of the precursor so that the water repellent area is provided between a portion of the layer A to be used for printing and a portion of the layer A in the fixing section not to be used for printing, supplying water or both water and ink to the resulting precursor to obtain a printing plate; and then carrying out printing while supplying water or both water and ink to the resulting printing plate.
