UV Reflector Geometry for Curing Inks and Coatings
Independently Controlled Reflectors:
A third reflector design has been pioneered by GEW. Here each reflector is independently controlled where the focus can be varied or even having one of two reflectors kept in the closed position. This again is a heat management technique used during jogging or low speed job set up on a press.The next phase of the reflector research involved measuring the spectral output of 15 different reflector constructions. The materials used to construct the test reflectors ranged from a basic polished aluminium material to more exotic non-metallic substrates coated with a number of specialized coatings. A standardized UV spectrophotometer was used to measure the entire UV energy output of each reflector construction. The energy measured included UVA, UVB, UVC and UVV, which were then summarized for total UV energy output. The bar graph table below summarizes the relative total UV irradiance measured.
