Method for changing a printing plate |
摘要 |
A method and apparatus for changing a printing plate on a plate cylinder in a sheet-fed offset printing machine is provided. The printing plate is first fed to the plate cylinder with its print-end edge leading the print-start edge. The print-end edge of the printing plate is then fixed in a first fixing device on the plate cylinder assigned to the print-end edge of the printing plate. The plate cylinder is then rotated in a direction opposite to the direction of rotation used during a printing operation to draw the printing plate around the outer circumference of the plate cylinder. The print-start edge of the printing plate is then fixed to a second fixing device on the plate cylinder that is assigned to the print-start edge of the printing plate and tensioned on the plate cylinder.
