A method for preparation of a lithographic printing plate, which comprises
the steps of: imagewise recording on a lithographic printing plate
precursor comprising a support having a hydrophilic surface and a
thermosensitive layer, the thermosensitive layer comprising at least one
of polymer particles and a microcapsule encapsulating an oleophilic
compound therein; and rubbing the printing plate precursor by a rubbing
member in the presence of a processing liquid to remove the
thermosensitive layer of non-image portions.
