Abstract (en)
A method of preparing a planographic printing plate from a light-sensitive planographic printing plate comprising an electrically conductive support provided thereon with a photoconductive layer comprising a photoconductor and an alkali soluble resin, said layer having a thickness of from 0.5 to 30 mu m, said method comprising: charging the photoconductive layer; forming an electrophotographic latent image on the charged layer imagewise from an original image; developing the latent image by applying toner to the exposed layer to form a toner image; and removing with an alkali solution that part of the photoconductive layer on which the toner image is not formed to form a relief image on the support; wherein the toner image is larger then the original image.
