ABSTRACT:
A method and apparatus for the ultraviolet curing of pigmented coatings having a thickness from about 1 mm to about 10 mm at a high curing rate and a relatively low energy consumption per unit area of coating cured. A coated substrate is irradiated by a first high UV source having a spectral energy distribution of the discharge which is high in the range from about 350 nm to about 450 nm and by a second UV source having a spectral energy distribution of the discharge which is high in discrete regions through the range of about 200 nm to about 450 nm. Each UV source is powered by at least about 300 watts per inch of width of the coating.
