Color Capture

The color capture device receives light signals reflected or transmitted by an object through a photoelectric sensor, converts them into electrical signals, and then analyzes the spectral components to obtain color values. It is used in industries such as printing and coatings to measure and compare product colors, ensuring color consistency between batches.
Selection
When selecting, consider matching the measurement aperture to the sample size, choose between fixed or portable types to suit the usage scenario, ensure the measurement geometry meets standards, review the instrument's repeatability data, and evaluate whether the accompanying software features meet color management requirements.
