<p>A plate-making method comprising: exposing a lithographic printing plate precursor comprising a hydrophilic support, a photosensitive layer containing a sensitizing dye having absorption in a wavelength of 405 nm, a hexaarylbiimidazole compound, a polymerizable compound, a binder polymer and a chain transfer agent and a protective layer in this order with a laser beam having a wavelength of from 350 to 450 nm; and developing the exposed lithographic printing plate precursor with a developer having pH of 10.0 to 12.5 and containing an anionic surfactant in an amount of from 1.0 to 10.0% by weight.</p> |
