Advanced LED Viewing Technology

JUST’s patented multi-colored LED technology creates a more complete and harmonious light spectrum than conventional fluorescent systems by combining multiple LED wavelengths into a highly accurate illumination source. This advanced technology provides excellent color rendering, low metamerism, and consistent spectral performance throughout the entire operating life of the system.

The Fresnel-type prismatic lens provides uniform illumination across the entire viewing surface while minimizing glare and reflections. This allows professionals to accurately evaluate large-format prints, packaging, textiles, coatings, and other color-sensitive materials under controlled lighting conditions.

Designed for Large Format Soft Proofing Workflows

The DLS proofStation 40 Large Format SP LED is engineered for modern color-managed environments where accurate monitor-to-print comparison is essential. The included monitor mount allows users to position a calibrated display within the standardized viewing environment, creating a reliable workflow for comparing digital proofs with physical samples.

With adjustable LED brightness, professionals can match the viewing station illumination to monitor luminance for soft proofing applications. This helps ensure consistent evaluation between displayed artwork and printed output while maintaining accurate D50 and D65 viewing conditions.
