Abstract: 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.

Abstract: A color measurement system includes a measurement patch (200) utilizable on a continuous sample of color printed matter. The patch (200) has a first predefined shape with a color reference area (202) centrally located on the patch (200) and a high contrast feature (204) located proximate to an edge of the patch (200). A camera scans the sample and generates a location signal upon detection of the high contrast feature (204) which permits accurate positioning of a measurement sensor.

Abstract: Un système permettant de mesurer la qualité des couleurs sur des objets arrondis est décrit. Un support (18) comprend un mandrin (24) servant à maintenir l'objet en une position fixe. Le mandrin (24) comprend de préférence un élément expansible en forme de vessie (38) monté rotatif sur un axe (40). Le support (18) comprend un réflectomètre (10) qui lui est accouplé de façon à permettre un déplacement angulaire dans un plan fixe. La boîte métallique est serrée en une position fixe entre le mandrin (24) et le réflectomètre (10) de façon que le densitomètre soit placé selon une orientation radiale fixe par rapport à la surface de l'objet. Différents points sur la surface de l'objet peuvent être mesurés par la rotation et la translation de l'objet et/ou du réflectomètre (10). La commande du positionnement de l'objet en rotation et translation peut s'effectuer automatiquement.
