The paint itself is one of the factors affecting the color difference
After the standard of a paint color is set, the subsequent paint produced by the supplier must be produced according to this standard. Due to the limitation of raw materials and craftsmanship, there will always be differences between batches. When the batches fluctuate greatly, the color of the body or exterior parts will exceed the tolerance range. Therefore, at the end of the paint production process, the hue should be adjusted through the spray board test to meet the standard.
Spraying process and equipment is the second factor affecting color difference
Different spraying processes will have a great impact on hue. The same kind of paint, when sprayed by hand, will cause fluctuations in hue and chromatic aberration due to the instability of the film thickness; spraying with automatic equipment can ensure the stability of the film thickness and the stability of the hue. But different automatic spraying equipment will have different effects on the paint hue. For example, air spraying and electrostatic spraying will have different effects on the arrangement of metal powder in the paint, so the same paint will be sprayed with two kinds of equipment in the end, and the hue will be very different.
The difference between measuring instruments is the third factor affecting color difference
There are many kinds of instruments for hue measurement, and the final measurement results of different brands and different models of instruments are also different. Even if it is the same model Colorimeter of the same brand, there will be inter-unit differences between the two instruments. Chromatic aberrations occur when instrumented measurements from body and exterior suppliers do not match.
