Zusammenfassung: | The present invention refers to an arrangement for determining the thickness of a print applied to a print carrier.The applied print (2ʹ) whose thickness (c) is to be detertemined is orientated in a manner which enables the print (2ʹ) to be irradiated with light, e.g. light beams, emitted from a light source (51); in that the light is projected onto the print at an angle not greater than 90° in relation to a line orientated at right angles to the horizontal plane of the print; in that the respective magnitudes of a shadow image of the print thickness (c), produced by said light beams, and the extension of said shadow image along the carrier (2) are evaluated together with information relating to the prevailing angle of the light beams; and in that the height or thickness (c) of the print (2ʹ) above the surface (2a) of the carrier (2) is established on the basis of the thus evaluated magnitudes. |
