Abstract
A device for measuring elevations of a surface of a rotary body embodied as a cylinder, roller, sleeve, plate or flexographic printing plate for graphic industry machines includes a first motor for rotating the rotary body about an axis of rotation and a measuring device for contactless measurement which is part of or integrated into a mounter for printing plates. The measuring device allows the printing forme to be measured and analyzed to check mounting quality and to detect diameter differences. The measuring device preferably further includes a reference object, such as a wire tautened in an axially parallel direction, a second motor and, if desired, a further second motor for adjusting the measuring device and/or the reference object in a direction perpendicular to the axis of rotation. The device provides a fast way of measuring the elevations, such as flexographic print dots, with great accuracy.
