Abstract
A device for measuring a surface or elevations of the surface of a rotary body provided as a cylinder, a roller, a sleeve, or a plate for a graphic industry machine, includes a first motor for rotating the rotary body about an axis of rotation and a measuring device including at least one radiation source, at least one area scan camera, and at least one computer used to take contactless measurements on the surface which is permanently sticky and/or compressible and/or porous and therefore difficult to measure. The measuring device uses a virtual reference object saved on the computer to determine the concentricity of the rotary body on the basis of the measurement results. A system including the measuring device and a flexographic printing press is also provided.
