摘要： 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.

摘要： Provided are a washing device and a washing method that achieve prevention of development scum adhesion, development uniformity, and development speed at the same time. This washing device performs development using a washing solution while transporting the flexographic printing plate precursor after imagewise exposure. The washing device includes a transport unit that transports the flexographic printing plate precursor along a predetermined transport path and a development unit that performs development on the flexographic printing plate precursor. The development unit includes a brush which is used for the development and a driving unit which controls rotation of the brush around a rotation axis and movement of the brush. The brush removes an unexposed portion of the flexographic printing plate precursor to perform the development, and the rotation axis of the brush is a fixed axis passing through one point in the brush. The driving unit rotates the brush in a state in which the rotation axis of the brush passes through a surface of the flexographic printing plate precursor, and moves the rotation axis of the brush in at least one direction intersecting the rotation axis.

摘要： Provided are a coating device and a coating method which suppress the occurrence of exhaustion of a coating liquid. A coating device which applies a coating liquid to an upper surface or a lateral surface of a long substrate continuously traveling in a specific traveling direction has: a bar which is capable of being brought into contact with the upper surface or the lateral surface of the long substrate continuously traveling in the specific traveling direction via the coating liquid, and is rotated; and at least two stages of dam plates which are provided on the upstream side in the traveling direction of the long substrate with respect to the bar, and allow the coating liquid to flow to the long substrate via a space between the dam plate and the bar. The at least two stages of dam plates are arranged along the traveling direction.
