1. A method for curing ink in a printing system, comprising:
detecting a size of a curved reflector; and then
rotating the curved reflector and delivering light energy from a light source via a refractive cylindrical optic and the curved reflector to a work piece that includes the ink including generating a virtual image with the refractive cylindrical optic and reimaging the virtual image with the curved reflector to generate a multi-dimensional column of irradiance at the work piece, where the curved reflector is rotated to deliver at least a portion of the multi-dimensional column of irradiance to the work piece at an angle normal to a top surface of the work piece.
