An area array camera is positioned externally of the container at an angle to the container axis so as to receive an image of the illuminated portion of the container finish. The camera is oriented with respect to the light source such that a vertical check in the container finish reflects light energy from the source to the camera to create a bright a image of the check against a normally dark background. Vertical checks in the container finish are detected as a function of such reflected light energy. | |
