Wherever the color plays a key role, an objective method is needed to determine the color of a product consistently. Whether in product development, during the manufacturing process, but also across companies between suppliers and customers...
At first the spectral reflectance of the sample is determined with a spectrophotometer. From these reflectance values, the CIE tristimulus values X, Y and Z can be calculated, as well as the color coordinates for the Lab and the LCh color space.
You can enter the reflectance values in the following ways:
