Abstract: 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 an intensity in a range of 0.0003 W/cm2/nm to 0.05 W/cm2/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.

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.
