The measurement method is reflection and transmission! It is also possible to derive Munsell values based on the Munsell color system.
We conduct color measurement of plastic materials. The color of the material can be expressed numerically in terms of L (lightness), a, b (chroma), YI (yellowness), W (whiteness), and the color difference (Δ) compared to a reference, and it is also possible to derive Munsell values based on the Munsell color system. In addition to hue, we also measure optical properties such as haze, glossiness, refractive index, and transmittance. 【Measurement Conditions】 ■ Applicable Standards - JIS Z8722, JIS Z8781-4, JIS Z8730, JISK7373 ASTME313, ASTM D1925 ■ Measurement Method: Reflection, Transmission ■ Measurement Apertures: 30mmφ, 10mmφ, 6mmφ ■ Measurement Shapes: Sheet, Pellet ■ Equipment: Color Difference Meter ZE6000, Nippon Denshoku Kogyo *For more details, please download the PDF or feel free to contact us.
