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.
