Why does the water cup spray white (black) paint or powder coating still need customers to proofread samples?

Usually, the customer needs to confirm the color when spraying the custom-made color of the water cup, and the customer calls this method staring at the color sample. The advantage of this is that the color difference between the final color requested by the customer can be corrected in time when the color is modulated, but for customers with strict color requirements, it usually takes longer for color proofing.

Many customers think that white and black spraying and proofing do not need to follow up, because these two colors are not like other colors, as if black and white are purer and simpler, and they do not need to be treated like other colors. But this kind of thinking is not rigorous in the strict sense.

When there is no contrast in white proofing, everyone will agree that it is white, but once there is a contrasting color, you will find that there are many changes in white. Some white is yellowish, some white is gray, and some white is blue.

Recently, our company encountered such a case, the customer did not pay enough attention to white proofing, and asked us to follow our normal white proofing without providing us with color samples. After the proofing came out, the video confirmed that the customer also thought there was no problem, but when the customer brought the coloring sample to the scene for comparison, it was obvious that our white was cyanish, which would give people a very blunt feeling, and the guest's color sample was warmer. We analyze with customers as soon as possible and provide them with proofing again. Although this matter has been solved very well, there is a warning for us and our customers that white is not as pure as imagined.

The same goes for black. In the case of no contrast, black will not be found to change. In fact, black also has multiple shades. Black is a blend of gray and other colors. The heavier the gray, the darker the color. But if only gray is composed of black, in contrast to the black composed of other colors, the gray composed of gray will appear thin and gray, and the black is not thick enough.
