Specifications

The economic proofing station for 3B and 6B formats is the entry-level solution for our LED based stations. With the proven JUST LED technology, proofs can be matched under D50 and D65, while the UV component can be switched on and off. The special prismatic lens provides an even, glare and reflection free illumination.

unique JUST LED technology, Fogra certified according to ISO 3664:2009, Pat. No. US 8,592,748 B2
switchable: D50 and D65 each with and without UV component for color matching according to the old and new ISO 3664 and ISO 3668 standards
UV-ONLY: UV-A for the detection of optical brighteners
continuous dimming and USB interface for softproofing
no color shift when dimming
no warm-up phase after switching on
20 times the operating hours of fluorescent lamps (> 50,000 h) stable light conditions over the entire operating life
no tube replacement necessary
