Publication number: 20190023051Abstract: Provided are a printing plate, a method for manufacturing a printing plate, and a printing method that allow for high-resolution printing and efficient use of printing ink. The printing plate has an image area and a non-image area. The image area is formed by a layer containing silicone rubber. The non-image area is formed by a layer containing a fluorine compound on a surface of the layer containing silicone rubber. The height difference between a surface of the image area and a surface of the non-image area is 100 nm or less. The method for manufacturing a printing plate has the steps of subjecting a region of a surface of a layer containing silicone rubber to chemical treatment or physical treatment to form hydroxyl groups, the region being a region that becomes a non-image area; and binding a fluorine compound to the region, having the hydroxyl groups formed thereon, of the surface of the layer containing silicone rubber to form a non-image area.Type: ApplicationFiled: September 10, 2018Publication date: January 24, 2019Applicants: FUJIFILM Corporation, National Institute of Advanced Industrial Science and TechnologyInventors: Yasuyuki KUSAKA, Kenichi KODAMA
