PVB 151 illuminator LED

PVB Illuminators (Profi View Box ) allow an objective assessment of the color on the analog originals and test prints (proof) in the identical lighting conditions.

PVB illuminator by Lettero means:

• objective color assessment – ISO compliant devices
• 3 LED light sources – depending on needs, PVB can be equipped with up to three light sources D50, D55 and D65 with smooth light intensity adjustment
• wide range of models – from the simplest to the device options that meet the highest professional requirements
