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.
