The invention relates to a device for detecting and/or recognizing markings, in particular for manual handling, comprising a camera for recording a marking and at least one illumination device for illuminating a marking, characterized in that, for detecting and/or recognizing markings () on/at/in transparent marking carriers (), in particular having reflectively polished surfaces, the at least one illumination device () is arranged at a distance from the optical axis (A) of the camera () in such a way that the light reflection () generated by the at least one illumination device () at the surface of the transparent marking carrier () is arranged at least alongside the marking represented in the camera image, preferably outside the detection region of the camera (). The invention furthermore relates to a method in which, for detecting and/or recognizing markings () on/at/in transparent marking carriers (), in particular having reflectively polished surfaces, a marking is illuminated by at least one illumination device () spaced apart from the optical axis (A) of the camera () in such a way that the marking appears in inverted fashion in the camera image, in particular as a bright marking on a dark background, and the light reflection () generated by the at least one illumination device () at the surface of the transparent marking carrier () is arranged at least alongside the marking represented in the camera image, preferably outside the detection region of the camera ().

Device and method for detecting and/or recognizing markings in/at/on transparent marking carriers

The invention relates to a method for the machine-reading of markings on/in transparent, especially pane-type, marking carriers, especially glass panes, according to which the marking carrier () is illuminated with UV light at least during the period of a machine-reading process of a marking, especially by means of a reading device (), in order to increase the contrast between a marking () and the marking carrier (). The invention also relates to a device for the machine-reading of markings in transparent, especially pane-type, marking carriers, especially glass panes, comprising at least one reading device () for markings arranged on/in a marking carrier, and at least one illumination device () is provided for increasing the contrast between a marking () and the surrounding transparent marking carrier () by illuminating the marking carrier () with UV light.

Method and apparatus for machine-reading markings on/in transparent marking substrates

Coating compositions, in particular for laser-supported treatment (in particular inscription) of glass surfaces are described, wherein the coating compositions contain at least one silver compound which is soluble in an aqueous and/or organic solvent and contains at least one binder. Methods for producing such coating compositions and methods for coating and treating glass surfaces are also described.
