An Objective Color Measurement System: Phase 4 Industry Trial
Abstract
A preoperational industry trial of the Color Measurement System developed by the U.S. Army Natick Research, Development and Engineering Center (Natick) was conducted through the cooperation of the Defense Personnel Support Center (DPSC), the Defense Contract Administration Services and textile finishers from industry. Using computer-operated spectrophotometers, production samples of two Woodland camouflage printed, battle dress uniform fabrics were instrumentally evaluated for shade acceptability at textile finishers' facilities, DPSC and Natick. The samples were visually evaluated at DPSC. A unique color difference equation (delta A) and acceptability (Chroma, Hue, Lightness) criteria developed by Natick were used to calculate the difference in color from the standard sample. The data from all test sites were compiled at Natick for analysis of the agreement between the visual and instrumental and the interinstrumental pass/fail judgements. Statistical analysis of the data indicates good agreement for all tests sites. In most cases the agreement was better that 93 percent. Given the satisfactory results of this trial, the implementation of the objective method for determining shade acceptability into the Army's quality assurance program will proceed: Keywords: Color, Textile industry, Spectrophotometers, Battle dress, Uniforms, Fabrics, Shade acceptability, Camouflage, Overgarment, Chemical protection.
