Why is the three angles color spectrophotoemter suitable for automobile paint color matching?
As for the color matching scheme of automobile paint, there are various colors in automobile paint. In order to improve the color matching speed, “triangle color difference meter + computer color matching system” has several characteristics compared with manual color matching:
- 1. It makes color matching job much easier.
- 2. It can gives different options.
- 3. Fast test twice can get formula.
- 4. Simple instrument interface which is easier to use.
- 5. Rubber pat to prevent the instrument from sliding when reading
- 6. Small aperture which is convenient to measure on curve surface
- 7. Bluetooth function can be custom made to connect with mobile devices.
- 8. Three angles to get the test result from different test angles.
- 9. Light weight, small size and easily carrying
- 10. Instrument adopts LED light which is long lifetime, can be used for 10 years.
Why need three angles spectrophotometer for color measurement?
Three angles color spectrophotometer is mainly used for car paint industry to measure the metallic paint, pearlescent paint and effective paint.
ΔMetallic Paint ΔPearlescent Paint ΔEffective Paint
Observing the effective paint from different angles, the human eye has different color perception.
So it is necessary to measure the car paint with multi-angles spectrophotometer.
As show in the following figure, the silver metallic paint has different reflectance under different angles.

How to find car paint formula?
We will need spctrophotometer and software, firstly. Now we introduce how to do it step by step.
Three Angles Spectrophotometer CS-390/392
Step 1. Car paint manufacturer will build the color formula database in instrument PC software.
Step 2. Open the PC software, click “database-find similar color”.
Step 3. Measure the sample, software will help to find the most similar color and get formula.
