OFFSET PRINTING METHOD AND APPARATUS, AND CYLINDRICAL BODY

To provide an offset printing method capable of performing excellent offset printing free of uneven printing even on a printing surface constituted of a tapered surface of a cylindrical body after being formed, by a simple configuration.SOLUTION: An offset printing method has: rotating holding means 111 for rotatably holding a metal cylindrical body 140 which is formed into a bottomed approximately truncated cone shape; and pressing transfer means 121 for transferring ink T at a transfer position P by moving the cylindrical body 140 held by the rotating holding means 111 while pressing a printing surface 142 of the cylindrical body, where the pressing transfer means 121 presses the cylindrical body 140, which is held by the rotating holding means 111 at the transfer position P, at a predetermined inclination to a rotation axis Cc of the cylindrical body.SELECTED DRAWING: Figure 4 【課題】簡単な構成で、成形後の筒状体のテーパ面で構成された印刷面に対しても、印刷ムラがない良好なオフセット印刷が可能なオフセット印刷方法を提供すること。【解決手段】有底略円錐台形状に形成された金属製の筒状体１４０を回転可能に保持する回転保持手段１１１と、転写位置Ｐで回転保持手段１１１で保持した筒状体１４０の印刷面１４２を押圧しながら移動してインキＴを転写する押圧転写手段１２１とを有するオフセット印刷方法であって、押圧転写手段１２１は、転写位置Ｐで回転保持手段１１１に保持された筒状体１４０の回転軸Ｃｃに対して所定の傾きで押圧すること。【選択図】図４
