Medium Pressure UV Curing lamps normally emit the Mercury Spectrum.
However different Spectrums can be created by adding rare earth metals to the lamp to change its spectral output. This means that the lamp can be matched to special or "non-standard" inks or coatings with different photoinitiator sensitivities such as UV LED inks, Whites and thick laquers for example. Please see list for spectral options to match to your coating or ink manufacturers specification.
