Three Angles Color Spectrophotoemter CS-390 Application
Part 1. Why need three angles spectrophotometer for color measurement?
1. 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
2. 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.

Part 2. How to find car paint formula?
We will need spctrophotometer and software, firstly. Now we introduce how to do it step by
step.
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.
Part 3. Use three angles spectrophotometers CS-390 to find car paint formula has the
following advantages.
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.
