The colorCommunicator 1 Light Viewer from Just Normlicht offers a coverage area of (10 x 12"). It can be used for classic reproduction applications or as part of the soft proof workflow. This standardized light viewer with a D50 illuminant communicates via the JUST USB interface with monitor calibration software to precisely match the soft proof on the monitor and the hardcopy in the viewing booth. The adJUST monitor calibration software sets the color values and luminance of the monitor automatically. Then the brightness of the colorCommunicator is set to exactly the same value as the monitor was calibrated to.
