Abstract
An offset printing method is suitable for high-precision printing. Errors caused by the relative movement between a blanket cylinder 4 and a form plate 10 and the rotation of the blanket cylinder 4 on its axis which are produced in a step of transferring an ink image to the blanket cylinder 4 from the form plate 10, are reproduced in the relative movement between the blanket cylinder 4 and a surface to be printed on 11 and the rotation of the blanket cylinder 4 on its axis in a step for printing the ink image on the surface to be printed on 11 from the blanket cylinder 4. The dimensional errors produced in the ink image transferred to the surface 12 of the blanket cylinder 14 of the offset printing methods are cancelled when transferring the ink image from the surface of the blanket cylinder 4 to the surface to be printed on.
