摘要： The present invention provides a printing method using a silver salt lithographic printing plate obtained by imagewise exposing a silver salt lithographic printing plate precursor comprising a support and, provided thereon, at least a silver halide emulsion layer and a physical development nuclei layer and then subjecting the exposed printing plate precursor to silver complex diffusion transfer development and using a dampening composition containing a nonionic surface-active agent represented by the following formula �I!: ##STR1## wherein R represents an alkyl group of 1-9 carbon atoms, and n.sub.1 and n.sub.2 are mol numbers necessary for the polymer having an average molecular weight of 250 or more, and n.sub.1 /n.sub.2 is 0.5-2, and a polymer represented by the following formula �II!: ##STR2## wherein m is a number which provides a number-average molecular weight of 2000-50000 for the polymer. By applying the above-mentioned dampening composition to the silver salt printing plate, a sufficiently high printing performance can be obtained without using colloidal silica or colloidal alumina in the dampening composition.
