Abstract: A device and a method for capturing the surface of a rotation body for a printing press, being a cylinder, a roller, a sleeve for a cylinder or roller, or a sleeve for a cylinder or roller having a printing form, include a motor rotating the body around an axial axis, a light source illuminating an area of the surface using optical light, and an optical camera capturing the illuminated area. An optical apparatus guides the light of first and second partial beams to an image sensor of the camera. The first partial beam tangentially strikes or touches the surface at a first point, then reaches the camera, and the second partial beam radially strikes the surface at a different second point, then reaches the camera. Rapid and precise measurements or types of measurements are performed simultaneously or using the same measures, for example in mounters for flexographic printing plates.
