Automatic Printing Plate Bender APB
The automatic printing plate bender makes it possible to bend an offset printing plate with unrivalled precision while referencing the position of the printing image independent of any format variations of the plate itself. In this way, a precise and axially parallel printing image position is achieved after mounting on the sleeve or plate cylinder.
Using two, practicably invisible measuring elements imaged on the edge of the printing plate, the current position of the printing image is determined with micrometer accuracy. An automatic positioning system brings the plate iteratively into the optimal position before bending. After arriving at the ideal position, the bending process is carried out automatically.
The printing makeready process is in this way considerably shortened, especially with offset printing presses where the bended edge determines the position and the parallelism of the printing plate, saving time and reducing waste.
