ABSTRACT:
A UV curing apparatus includes a single UV lamp providing a source of UV energy for irradiating ink on a substrate being conveyed through a UV curing station. Substantial reductions in the amount of energy absorbed by the substrate and substantial increases in conveying speeds may be obtained by use of a reflector means which preheats the ink to raise its temperature and then applies UV to cure the previously heated ink. The preferred reflector means has an upstream preheating section of a parabolic shape for providing IR radiation to preheat the ink and a second downstream section of elliptical shape to provide maximum UV radiation of the previously heated ink.
