<p>Disclosed is a method for producing a relief printing plate, wherein a rinsing liquid for the production of a relief printing plate, which is capable of easily removing dust produced on the printing plate during the engraving and has a small effect on the relief printing plate, is used. Specifically disclosed is a method for producing a relief printing plate, which is characterized by comprising, in the following order: a step of preparing a relief printing original plate that has, on a supporting body, a relief-forming layer containing a non-elastomer binder polymer, a plasticizer and a photothermal converter; a step of engraving the relief printing original plate by exposure to light using a laser; and a step of removing engraving dust with a rinsing liquid for the production of a relief printing plate, said dust being produced by the engraving. The method for producing a relief printing plate is also characterized in that the rinsing liquid for the production of a relief printing plate contains a nonionic surfactant.</p> |
