Scope of Application

工业生产中，不同批次的同种产品，往往会因材料、配料或生产工艺的偏差而造成货品之间的颜色差异。品检员虽然已仔细地对比过货品之颜色，但因为环境光源不标准，不同光线下所看到的颜色各异，货品色差很难判定。客商验货时会因为色差超出标准范围而投诉，甚至退货。有了标准光源对色灯箱，使检定货品之颜色在相同的光源及可控制的条件下进行，有效解决了因光源不标准而造成货品色差的问题。适用于纺织品、印染、印刷、塑胶、颜料、油漆、油墨、摄影等等行业的色牢度评定及颜色的异谱同色程度的评定。

【Operating Instructions】

In industrial production, color differences often occur between different batches of the same product due to variations in raw materials, ingredients, or manufacturing processes. Although quality inspectors carefully compare product colors, the lack of a standardized light source—and the fact that colors appear differently under different lighting—makes it difficult to assess color differences accurately.

**【Scope of Application】**

In industrial production, color differences often occur between different batches of the same product due to variations in raw materials, ingredients, or manufacturing processes. Although quality inspectors carefully compare product colors, the lack of a standardized light source—and the fact that colors appear differently under different lighting—makes it difficult to assess color differences accurately. During customer inspections, complaints or even returns may arise if color differences exceed acceptable limits. The standard light source color matching cabinet allows color evaluation to be performed under controlled, consistent lighting conditions, effectively eliminating color discrepancies caused by non-standard light sources.

It is suitable for color fastness evaluation and metamerism assessment in industries such as textiles, printing and dyeing, printing, plastics, pigments, paints, inks, and photography.

**【Light Source Specifications】**

- **D65 Light Source:** Color temperature 6500 ± 200 K, color rendering index Ra ≥ 95. International standard artificial daylight simulating average north sky daylight. Used for color matching under natural light conditions; meets general requirements, and most customers specify D65 for color evaluation.

- **A Light Source:** Color temperature 2800 K. Tungsten filament lamp simulating household or hotel lighting; used as a reference light source for color comparison.

- **TL84 Fluorescent Lamp:** Color temperature 4000 K. Simulates commercial lighting in Europe, Japan, and China. Often specified by European and Japanese customers for color evaluation.

- **F Light Source:** Color temperature 4100 K. Tungsten filament lamp simulating household or shop window lighting. Primarily used in combination with other light sources to detect metamerism.

- **CWF Light Source:** Color temperature 4200 K. Simulates cool white fluorescent lighting commonly used in American stores.

- **U30 Light Source:** Color temperature 3000 K. Simulates warm white fluorescent lighting used in American commercial spaces; a rare-earth fluorescent lamp for retail lighting.

- **UV Light Source:** Peak wavelength 365 nm. Ultraviolet light used to detect fluorescent whitening agents and control whiteness levels (e.g., comparing very white fabrics).
