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.

Washing device

A lithographic printing plate precursor including a hydrophilized aluminum support, and a water-soluble or water-dispersible negative type image recording layer provided on the aluminum support, in which an arithmetic average height Sa of a surface of an outermost layer on a side where the image recording layer is provided is in a range of 0.3 &#x3bc;m to 20 &#x3bc;m; a method of producing a lithographic printing plate precursor; a lithographic printing plate precursor laminate formed of the lithographic printing plate precursor; a plate-making method for a lithographic printing plate; and a lithographic printing method.

Lithographic printing plate precursor, method of producing same, lithographic printing plate precursor laminate, plate-making method for lithographic printing plate, and lithographic printing method

Provided are a lithographic printing plate precursor including: a hydrophilized aluminum support, and a water-soluble or water-dispersible negative type image recording layer provided on the aluminum support, in which an arithmetic average height Sa of a surface of an outermost layer on a side opposite to a side where the image recording layer is provided is in a range of 0.3 &#x3bc;m to 20 &#x3bc;m; a method of producing the lithographic printing plate precursor; a lithographic printing plate precursor laminate formed of the lithographic printing plate precursor; and a lithographic printing method.

Lithographic printing plate precursor, method of producing same, lithographic printing plate precursor laminate, and lithographic printing method

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 supportincludes a back coat layerhaving an arithmetic average surface roughness Ra of 0.5 &#x3bc;m or greater due to a surface roughness structure in which thin film portionsand thick film portionsare continuously formed on a rear surface of the belt-like support
