Color measurement system including lateral moving measurement carriage

摘要

A color measurement system (100) for laterally determining the chromatic characteristics of a printed substrate conveyed by a conveying apparatus. The system includes a measurement carriage (102) and a backing carriage (114). The measurement carriage includes a measurement head (104) for laterally moving across the width of the printed substrate and a measurement magnetic coupler (106). The measurement carriage is slidably mounted onto a measurement rail (112) positioned on a first side of the printed substrate. The backing carriage includes at least one backing surface (116W, 116B) and at least one backing magnetic coupler (18W, 118B). Each of the at least one backing magnetic coupler is associated with a respective one of the backing surface. Each of the at least one backing magnetic coupler can be coupled with the measurement magnetic coupler for coupling the measurement carriage with the backing carriage. The backing carriage is slidably mounted onto a backing rail (120) positioned on a second side of the printed substrate, opposite the first side. A selected one of the measurement carriage and the backing carriage includes a motor (110) for moving across a respective one of the measurement rail and the backing rail. Another one of the measurement carriage and the backing carriage is moved across another one of the measurement rail and the backing rail by being coupled with the first one of the measurement carriage and the backing carriage.
