Claim:
An ink jet printer, comprising: an applicator disposed on a print carriage, said applicator adapted to apply an amount of a coating composition to a substrate; a first light source producing a light having a wavelength in a range of about 100 nm to about 1200 nm and an intensity in a range of about 0.0003 W/cm 2 /nm to about 0.05 W/cm 2 /nm and arranged to expose at least a portion of the coating composition to the light; a second light source producing a light having a wavelength in a range of about 100 nm to about 1200 nm symmetrical with the first light source, and both the first and second light sources positioned parallel to an axis in the direction of print carriage motion; and the first and second light sources disposed on opposite sides relative to the print carriage for illuminating a print surface, wherein said first and second light sources are not mounted on said carriage, and wherein light from said first and second light sources provides substantially all energy required to cure said coating composition.
