Abstract
The invention is an apparatus configured to provide self-alignment in use when measuring the print quality of an encoded indicium. The apparatus is configured to exclude ambient light, and to align an encoded indicium located at a first aperture defined in a first surface of the apparatus with an imager positioned at a second aperture defined in a second surface of the apparatus. A source of illumination is provided to illuminate the encoded indicium during an interval when the encoded indicium is undergoing a verification process. An illumination control is provided to control the source of illumination. The apparatus can be controlled using a computer and a computer program recorded on a machine-readable medium.
