A method for producing a lithographic printing plate is provided, wherein,
in the non-alkaline development of a lithographic printing plate
precursor having a protective layer, even if the protective layer
components are mingled into the developer, the reduction in development
removability of the image recording layer and the generation of
development scum can be inhibited; an on-press development type
lithographic printing plate precursor with excellent inking property,
high scratch resistance, satisfied on-press developability and good fine
line reproducibility is provided; and a lithographic printing method is
provided, each of which is a method for producing a lithographic printing
plate, comprising: imagewise exposing a lithographic printing plate
precursor comprising a support, an image recording layer and a protective
layer, and rubbing the plate surface by a rubbing member of an automatic
processor in the presence of a developer at a pH of 2 to 10 to remove the
protective layer and the image recording layer in the unexposed area; a
lithographic printing plate precursor comprising a support, an image
recording layer removable with a printing ink and/or a fountain solution,
and a protective layer containing a polyvinyl alcohol having a carboxyl
group and/or a sulfonic acid group within the molecule; and a
lithographic printing method comprising on-press development.
