用色差仪控制汽车油漆色差

来源:色差仪 浏览: 发布日期:2017-12-07
车身的油漆色差控制是一项非常复杂的工作,即使有色差仪和色彩管理系统的配合这种复杂性也不会完全被平常化,所以我们能做的就是尽量利用色差仪多测量记录精准的色彩数据,同时控制还色差仪的测量误差,加强色彩管理的力度。

单色漆颜料排列均匀、致密,其各角度反射光均匀,所以,单色漆只计算45°角反射光;金属漆等效果涂料中金属铝粉排列有定向性,各角度值均不同,差异较大,所以至少计算25°、45°和75°3个角度的反射光。通过大量验证人眼视觉评估和色差仪全民快乐8测量结果的一致性,得到以下常见油漆颜色的颜色允差,按照这个允差进行色差控制,可以很好保证仪器测量和人眼目视的一致性。允差1(DEp):油漆车身与油漆件之间的容差范围,适用于整车油漆色差测量评判;容差2(DEp):油漆车身及油漆件与标准色板之间容差范围,适用于零部件过程质量控制测量评判。油漆车身和油漆件涂装工艺调试时要严格按照标准色板进行,满足下表中颜色允差要求要求。
