The counterfeit ultraviolet detector DORS 125 has a combined higher lighting source that offers the following:
Secure reflected white light control of printing types, fragments of images made by optically variable inks, latent images, security holograms, printing defects, and potential erasures. Secure UV-control of absence of general paper luminescence background, presence of luminescent areas (image fragments, security threads and fibres).
Transmitted white light allows for the secure verification of watermarks, protective fibres, and matching images of the front and back of banknotes when used on single or fanned out banknotes that are positioned vertically.
