For a proper color evaluation, ensure cleanliness, use standardized observation conditions, eliminate stray light, and periodically change the lamps.

Techniques of measuring color are visual color comparison, colorimetry (with colorimeters) and spectrophotometry (measuring spectral reflectance), and image analysis. Both techniques measure the reflection or absorption of light by materials and are commonly quantified. Therefore standardized in color spaces such as CIELAB or RGB.

For accurate results, install a clean and well temperature-regulated booth that is also sheltered from reflective surfaces and direct sunlight. Ambient light in the booth and the surrounding area from where the light is being viewed should not mix.

Depending on the scale of the manufacturer, its matte, low-sheen finish can be called gloss level 3. Overall, gloss levels in certain standards go between 1 (flat) to 7 (high gloss). Level 3 is considered low-gloss or satin-like.

Samples should be cleaned, dried, and scratched-free to obtain consistent haze measurements.

The CCC is much like the CAC yet it frequently has advanced programmable lighting, sophisticated electronic control systems that allow for light source switching, and advanced visual testing.

A coating thickness gauge measures coating thickness. It measures coating thickness using three different principles: magnetic induction, eddy current, or ultrasonic. Depending on the coating type and the coating's substrate material, the appropriate principle is selected. For industrial and laboratory use, most of these units deliver accurate, non-invasive readings.
