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.

Abstract: A system for measuring the color quality of rounded objects is disclosed. A stand has a mandrel for holding the object in a fixed position. Preferably, the mandrel includes an expandable bladder mounted for rotation on an axle. The stand has a reflectometer coupled thereto in such a way as to permit angular movement of the densitometer in a fixed plane. The can is clamped in a fixed position between the holding means and the densitometer such that the densitometer is in a fixed radial orientation relative to the surface of the object. Different points on the surface of the object may be measured by rotating and translating the object and/or the reflectometer. Rotational and translation control of positioning can be performed automatically.

Abstract: For use with a printing apparatus that has a plurality of printing rollers, at least one ink fountain, and at least one inking blade that is positioned adjacent one of the inking rollers, the inking blade having a plurality of adjusting keys thereon, an ink control system connected to the inking blade for controlling the adjustment the adjusting keys. The ink control system comprises a system unit for controlling the overall operation of the ink control system, an operator console for inputting commands which control the adjustment of the adjusting keys, a servo powder unit for controlling the adjustment of the adjusting keys, and a plurality of servo modules each of which performs the adjustment of one of the adjusting keys by actuating the one adjusting key.
