To provide a gravure offset printing method capable of effectively inhibiting generation of pin hole in a wiring pattern.SOLUTION: The gravure offset printing method is a gravure offset printing method for printing a wiring pattern on a matter to be printed, having a doctoring step of filling an ink into a recessed portion 30 arranged on a gravure plate 10 and removing the ink existed in an area other than the recessed portion 30 in the gravure plate 10; an accepting process of moving the ink from the gravure plate 10 to a blanket; and a transfer process of moving the ink from the blanket to the article to be printed, in which the gravure plate 10 has many projections 40 arranged between the recessed portions 30 and projecting in a thickness direction of the gravure plate 10 from a bottom surface 30a of the recessed portion 30.SELECTED DRAWING: Figure 1 【課題】配線パターンにピンホールが発生することを効率的に防止できるグラビアオフセット印刷方法を提供する。【解決手段】本発明のグラビアオフセット印刷方法は、配線パターンを被印刷物に印刷するグラビアオフセット印刷方法であって、グラビア版１０に設けられた凹部３０にインクを充填し、グラビア版１０における凹部３０以外の領域にあるインクを除去するドクタリング工程と、グラビア版１０からブランケットにインクを移動させる受理工程と、ブランケットから被印刷物にインクを移動させる転写工程と、を有し、グラビア版１０は、凹部３０の間に多数設けられ、凹部３０の底面３０ａよりもグラビア版１０の厚さ方向に突出する凸部４０を有する。【選択図】図１
