A device for measuring the concentration of a layer of wet printing ink, characterized in that it forms a Brewster's angle with respect to the normal to . 2. The apparatus according to claim 1, wherein the illumination optical axis of the ink layer is arranged within a range of ±15% of the Brewster's angle with respect to the normal line. 3. The apparatus according to claim 1, wherein the illumination optical axis of the ink layer is arranged exactly at Brewster's angle with respect to the normal line. 4. The device according to any one of claims 1 to 3 of the utility model registration claim, wherein the photoelectric converter is arranged within the diffusely reflected light.
