This invention is an advance in coating chemistry, curing technology, related apparatus and the products made thereby. The invention encompasses a substrate bonded to a coating cured, at least in part, cationically by a light having a wavelength in a range of 100 nm to 1200 nm and intensity in a range of 0.0003 W/cm/nm to 0.05 W/cm/nm. Methods and systems for coating substrates and curing the coated products are encompassed. The invention encompasses apparatus and ink jet printers utilizing this curing technology. The invention also includes providing a 'moving shadow' from ultraviolet light that is uniformly distributed over a print zone defined by a path of carriage motion illuminated by the light.
