摘要:
AbstractBecause of the subjective nature of determining visual color‐match acceptability, we have for many years hoped that color measurement would provide objectivity for clear‐cut decisions. Despite impressive advances in spectrophotometers and computer software, few produceruser programs have been successful using only numerical data and with no visual override. Most companies “accumulate data” but make final decisions visually. Considering the many observers making color‐match decisions at color producer sites, molding plants and assembly plants, Ford set out to establish a plan for fully objective analysis. While developing the plan, certain guidelines became critical to good correlation of visual to measured data. A pilot program is described in which the resin producers certify batches of color concentrate or precolored resin as meeting certain measured criteria. the parts are then molded and installed in vehicles and are not challenged visually but are monitored for the record. Good color match quality has resulted. © 1995 John Wiley
