RESIN LETTERPRESS PRINTING PLATE AND ITS MANUFACTURING METHOD AS WELL AS PRINTER

To constitute a guide surface of a non-stepped part having no step in a joint part where one end part of a marginal zone formed on a plate surface side and its other end part are butted, even though there is a step in a seam part of a resin letterpress printing plate around which a printing body cylinder is wound.SOLUTION: A concave part 40 is constituted by notching one end part side of a marginal zone 34 formed on both sides of a plate surface in a longer direction, and, a convex part 41 is constituted by protruding the other end side of the marginal zone 34 in a longer direction, in a resin letterpress printing plate 30, when wound around the plate body cylinder, a joint part 44 is formed by butting one end side concave part 40 of the marginal zone 34 and its other end side convex part 41, and in a joint part of the marginal zone 34, a guide surface of non-stepped part continuing to the marginal zone 34 is constituted.SELECTED DRAWING: Figure 3 【課題】版胴シリンダに巻き付けられる樹脂凸版印刷版の継ぎ目部に段差があっても、版面両側に形成されるマージナルゾーンの一端部とその他端部とが突き合わされる接合部に段差の無い非段差部のガイド面を構成したもの。【解決手段】版面の両側に形成されるマージナルゾーン３４はその一端部側を長手方向に切欠いて凹部４０が構成され、かつ、マージナルゾーン３４の他端部側を長手方向に突出させて凸部４１が構成され、樹脂凸版印刷版３０は、前記版胴シリンダに巻付けたとき、マージナルゾーン３４の一端部側凹部４０とその他端部側凸部４１とが突き合わされて接合部４４が形成され、マージナルゾーン３４の接合部には、マージナルゾーン３４に連続する非段差部のガイド面が構成されたことを特徴とする樹脂凸版印刷版である。【選択図】図３
