Ink-jet printing systems and methods for extending air fade resistance of ink-jet prints

摘要

The present invention is drawn to systems and methods for reducing air fade of ink-jet inks, particularly with respect to dye-based ink-jet inks printed on porous media. Specifically, a method of printing an image on porous media with increased air fade resistance can comprise the steps of (a) providing an ink-jet ink, wherein the ink-jet ink comprises a dye and a water-soluble or water dispersable copolymer in a vehicle carrier; (b) providing a porous media substrate having an inorganic porous media coating, wherein the inorganic porous media coating provides voids for the ink-jet ink to fill; and (c) ink-jetting the ink-jet ink onto the porous media substrate, thereby providing an image having increased air fade resistance.
