Abstract
A color measurement system includes a measurement patch utilizable on a continuous sample of color printed matter. The patch has a first predefined shape with a color reference area centrally located on the patch and a high contrast feature located proximate to an edge of the patch. A camera scans the sample and generates a location signal upon detection of the high contrast feature which permits accurate positioning of a measurement sensor.
