Correlation Studies on a Prototype Color-Measurement System
Abstract
A joint US Army Natick Laboratories-Defense Personnel Support Center prototype color-measuring system, which consists of an Applied Color Systems Spectro Sensor at each installation, was evaluated for individual repeatability and for correlation between the two instruments. The samples (20 fabric swatches, 15 porcelain tiles and a color-difference pair) were measured for short-term (10 days) and long-term (5 to 10 weeks) repeatability. Each instrument was found to show a repeatability (as determined by the mean color difference from the mean (MCDM)) of 0.14 color difference units or less for the two time periods studied. The largest color difference observed between the two instruments for these samples was 0.18 color difference units. Measurement of the color-difference pair, as well as measurements in the infrared region (up to 900 nm), gave similar results. The repeatability exhibited by the two instruments and the correlation of their measurements is considered to be quite good and the system should be suitable for the needs of the Defense Department.
