ABSTRACT OF THE DISCLOSURE A method of increasing the water fastness and print quality of an ink employed in ink-jet printers is pro- vided. The method involves providing a reactive species that reacts with a component in the substrate (i.e., paper) to form a polymer that binds the dye in the ink to the polymeric lattice. Alternatively, a separate reactive component may be deposited on the substrate on the same location as the reactive species which causes a polymeric reaction to occur. In this case, the ink may be in one or the other or both reactive components. An ink-jet printer having indexed orifices permits registration of deposited droplets of ink and reactive species to form the desired product.
