摘要
贵金属合金颜色是影响首饰外观和展示饰品个性化的重要因素,但行业内目前对测试贵金属合金颜色的条件缺乏统一要求,致使贵金属颜色无法准确比较和溯源.基于贵金属合金因测试条件不同,其颜色结果不同而无法进行准确比较的问题,采用光谱光度测色法,针对标准色度观察者、仪器设备、样品大小和样品表面条件4个影响因素进行实验,对色空间坐标的变化规律和色差进行分析.结果表明:经过校准的分光光度计和测色仪均能准确测试贵金属颜色;适宜的测试条件为CIE1964标准色度观察者,样品大小完全覆盖仪器测试孔,样品测试区域均匀、平整、洁净、无缺陷.研究结果可为贵金属合金颜色的准确测试提供参考依据.
Abstract
The colour of precious metal alloys is an important factor that affects the appear-ance and personalization of jewelry.However,the industry lacks of unified requirements for the colour of the test conditions of precious metal alloys,which makes it impossible to accu-rately compare and trace the colours of the precious metal.Based on the problem of the ina-bility to accurately compare the colour results of the precious metal alloys due to different testing conditions,spectral photometry was used to conduct experiments on four influencing factors:standard chromatics observers,instruments,sample sizes,and sample surface con-ditions.The change rule of colour space coordinates and values of colour difference are ana-lyzed.The results show that both the calibrated spectrophotometer and colorimeter can accu-rately test the colour of the precious metals.The suitable testing conditions are CIE1964 standard colorimetric observer,with the sample size completely covering the instrument test hole,and the sample testing area being uniform,flat,clean,and defect free.The research results can provide a reference basis for the accurate testing of precious metal alloy colours.
