Standard Light Box for Proofing

The proofing standard light box provides a stable and uniform light environment by simulating standard lighting conditions such as daylight and fluorescent lamps. It is used in industries such as printing and textiles to compare colors under fixed light sources, ensuring consistency in color evaluation and avoiding visual deviations caused by lighting differences.
Selection
When selecting, ensure the light source type covers commonly used standards such as D65 and CWF, with illuminance uniformity no less than 85%. The interior of the cabinet should be painted in neutral gray to avoid reflective interference. The observation area should be sized to accommodate the sample, and regular calibration should be performed to account for light source attenuation. The cabinet structure must be sealed to prevent dust ingress.
