SCI & SCE
Measuring Glossy Plastics
Measure glossy plastic color with a fixed specular condition, clean handling, controlled orientation and a separate gloss requirement where appearance depends on both.

What Is an Integrating Sphere and How Does It Work?
In a d/8° spectrophotometer, an integrating sphere provides diffuse illumination while the detector observes sample-reflected light at 8°.

Spectrophotometers for Automotive Paint
An automotive color match is judged where panels meet, under changing daylight and artificial light, often alongside a high-gloss or effect finish. That makes instrument selection and measurement…

d/8° vs 45°/0° Geometry: Choosing the Right Color Measurement
Color is shaped by the way light reaches a surface and the angle from which it is viewed. Measurement geometry defines those conditions for a spectrophotometer, making it…

SCI vs SCE Explained: Specular Included and Excluded
SCI includes specular reflection and generally reduces finish-related color variation; SCE excludes it and is more sensitive to finish.
