| 摘要 |
A cylindrical printing plate precursor of the present invention comprising a cured resin sheet formed into a cylindrical shape, the cylindrical printing plate precursor comprising an overlap margin part comprising opposite end parts of the cured resin sheet superimposed on one another, each end part of the cured resin sheet in the overlap margin part having a thickness that is smaller than the thickness of the cured resin sheet other than in the overlap margin part, and a joining part, in the overlap margin part, in which a hole providing communication between the opposite end parts of the cured resin sheet is filled with a cured resin, the overlap margin part having a width of least 5 mm but no greater than 25 mm, the joining part having a size of at least 1 mm but no greater than 3 mm, and the joining part having a cross-sectional area in the plate surface direction of at last 5% but less than 80% relative to the cross-sectional area in the plate surface direction of the overlap margin part. |
