Method and apparatus for printing on opposite sides of a web

摘要

The printer (10) has a support frame (32) with a horizontal platform (36) on which the main body is pivotally supported. The base of main body (52) is positioned on the support frame platform. A rotatably driven impression cylinder (60) is supported by the base of the main body. A rotatably driven plate cylinder (62) supported by the main body base is opposingly arranged to the impression cylinder, to receive a continuous printing sheet (12). The plate cylinder has an inked surface for transferring the image on the one side of printing sheet. The main body base reverses the position of both impression and plate cylinders, so that the printing image is formed on other side of the printing sheet.
