Provides is a method for manufacturing lithographic printing plates with good print durability and print staining properties, in which the content of organic solvents with pH levels close to neutral is small, the quantity of chemicals employed is low, the quantity of waste solution generated is small, and processing can be conducted in a single bath. The method for manufacturing lithographic printing plates comprises (A) exposing to a negative-type lithographic printing plate precursor comprising an image-forming layer that is curable by exposure to light on a support having a hydrophilic surface; (B) developing with a developer having a pH of 4 to 10 the negative-type lithographic printing plate precursor that has been exposed; (C) treating with a burning surface-treatment liquid the negative-type lithographic printing plate precursor that has been developed; and (D) subjecting the negative-type lithographic printing plate precursor to a burning treatment; and by an interval between the developing (B) and the treating with a burning surface-treatment liquid (C) of from 1 minute or more to 10 hours or less, during which time no water-washing or gumming is incorporated. |
