<p>A system for measuring the color quality of rounded objects is disclosed. A stand (18) has a mandrel (24) for holding the object in a fixed position. Preferably, the mandrel (24) includes an expandable bladder (38) mounted for rotation on an axle (40). The stand (18) has a reflectometer (10) coupled thereto in such a way as to permit angular movement of the reflectometer (10) in a fixed plane. The can is clamped in a fixed position between the mandrel (24) and the reflectometer (10) 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 (10). Rotational and translation control of positioning can be performed automatically.</p> |
