皮革生产中的颜色色差容限及色差问题

Color Tolerances and Color Differences in Leather Manufacture

皮革生产厂家及销售商为了能在竞争对手中脱颖而出,千方百计增加产品副加值,提高产品质量。产品质量的提高,从视觉方面来讲主要是在设法获得均匀的颜色质量基础上满足合理设定的颜色色差容限。然而,要定制适宜的颜色色差容限,厂家与客户之间必须事先经过诚恳的商谈,以客观的、可测量的方式进行描述,以避免交货时可能出现的争议。本文阐述了同色异谱、色差系统、测色系统及皮革染色过程各因素对颜色复制的影响,并对颜色质量评估提出可行性建议,以供厂家及客户在进行产品评估时进行参考。

Leather manufactures and sellers, to distinguish themselves from competitors, seek to add value to their products for the consumer. One method to achieve this goal is improvements of product quality. Uniformity of color quality and well-defined manufacturing color tolerances are essential. The statement seems simple, but the process can bring problems unless tolerances are agreed to in frank discussions between the buyer and seller. Tolerances must be described in objective, measurable terms. By understanding metamerism, color difference systems, measuring systems, and dyeing process variables, pieces of workable advice were put forward for the buyer and seller.
