LED light booth Light4Color 402

color viewingcolor matching

Overview
Discover the latest kind of color proofing with the color matching cabinet Light4Color 402. The optimized LED control system facilitates precise visual assessment under multiple standard and selectable illuminants. UV content can be switched on/off and proofing presets are stored and recalled at the touch of a button.

Features

• Optimized light distribution and high spatial uniformity
• CAD-based prismatic diffuser for shadow- and glare-free viewing
