Abstract

The present invention provides a method for mounting a lithographic printing plate carrying a lithographic image on a polyester film support having a thickness of 0.1mm to 0.35mm and a Young modulus of at least 4300N/mm2, on a plate cylinder of a web press, said plate cylinder having a channel for receiving the lead edge of the lithographic printing plate and said method comprising the steps of:
  • (1) bending the lithographic printing plate along a line parallel to registration-line openings near its lead edge and perpendicular to a direction of orientation of said polyester film wherein the Young modulus is at least 4300N/mm2;
  • (2) applying an adhesive to the backside of the lithographic printing plate at least near its lead edge and trailing edge;
  • (3) inserting the lead edge in a longitudinal channel of the plate cylinder and;
  • (4) wrapping the lithographic printing plate around the plate cylinder while pressing the adhesive against the plate cylinder.
    • The present invention further provides a lithographic printing plate carrying a lithographic image on a polyester film support and having a lead edge and a trailing, said lithographic printing plate being bended perpendicular to a direction of orientation of said polyester film wherein the Young modulus is at least 4300N/mm2 and parallel and adjacent its lead edge under an angle of less than 90° and wherein the backside of said lithographic printing plate is provided with an adhesive at least near the lead edge and trailing edge.
