Color Shade Instrumentation Correlation Study: Statistical Analysis. Revision

摘要

Military fabric suppliers currently use spectrophotometers as part of their quality control process; however, when the suppliers ship their fabric to clothing manufacturers, the procedure for determining whether the fabric meets the military shade standard depends solely on visual evaluation. Visual evaluation by trained shade evaluators is widely considered superior to instrumentation because the human eye is more sensitive to shade variation. The feedback from visual evaluations that is provided to fabric suppliers is often general and vague, and suppliers have difficulty making the proper adjustments to their printing and dying processes. Spectrophotometer measurements, on the other hand, provide more quantitative feedback, but there have been concerns regarding the consistency of measurements. LMI and Army Natick Soldier RDEC assessed the use of spectrophotometers as an aid to military shade evaluators, asking two main questions: Do spectrophotometer measurements collected at different locations produce consistent color measurements. To what extent do human visual evaluations agree with spectrophotometer evaluation.
