Professional Color Evaluation Performance
The DLS Color Viewing Light v7 L is engineered for industrial color matching and high-volume production quality control workflows. It delivers highly uniform spectral output with excellent metamerism control, making it ideal for evaluating large printed proofs, packaging materials, textiles, coatings, and oversized visual samples.
D50 and D65 illuminants exceed ISO viewing standards, while UV-A capability enables accurate detection of optical brighteners and fluorescence effects. Digital dimming ensures precise luminance matching for controlled production environments.
Optimized for Soft Proofing & Quality Control
With USB connectivity and stepless dimming, the v7 L supports advanced soft proofing workflows by allowing precise matching between display calibration and physical proof illumination. The system ensures consistent visual evaluation across production environments, improving accuracy and reducing color errors.
Uniform, Glare-Free Illumination
A CAD-based prismatic diffuser system delivers highly uniform illumination with minimal glare and reflection. The wide-format asymmetrical design supports a fixed viewing position, making it ideal for consistent inspection of large flat materials such as press sheets, packaging layouts, and wide-format prints.
