Abstract
Apparatus for reducing variations in total indicated run-out and taper in a printing roller, includes a detector which detects variations in total indicated run-out and taper in a surface of the printing roller, and a laser which ablates the surface of the printing roller. A control device controls the laser to ablate the surface in a manner to reduce variations in the total indicated run-out and taper in the printing roller, in response to the detector, while there is relative rotation and lengthwise movement between the printing roller and the laser and detector. Also, a printing plate is mounted on the printing roller, and the control device controls the laser to reduce the total indicated run-out and taper by further ablating a surface of the printing plate. The control device further controls the laser to etch an image into the printing plate.
