Abstract: Provided is a washing device that has a small device configuration, is excellent in maintainability, and further has a high productivity. The washing device performs development using a washing solution while transporting an imagewise exposed flexographic printing plate precursor. The washing device has a transporting unit that transports the flexographic printing plate precursor along a transport path having a curved transport passage and a linear transport passage, using a leader and a developing portion that performs development by removing an unexposed portion of the flexographic printing plate precursor. The transporting unit transports the flexographic printing plate precursor using a winding transmission method or transports the flexographic printing plate precursor using a method of winding a traction member provided at the leader.

Abstract: Provided are a planographic printing plate precursor, a laminate thereof, and a method of producing a planographic printing plate precursor capable of satisfying all purposes for eliminating interleaving paper used for preventing scraping and peeling, preventing adhesion, imparting a plate-separating property for preventing multiple-plate feeding, and preventing scratches. The planographic printing plate precursor which includes a polymer layer on a surface of a belt-like support 12 includes a back coat layer 70 having an arithmetic average surface roughness Ra of 0.5 μm or greater due to a surface roughness structure in which thin film portions 60 and thick film portions 62 are continuously formed on a rear surface of the belt-like support 12.
