A process for providing an ozone resistant dye-based image, and a resulting image, includes jetting an ink containing the dye onto a microporous media surface to form a dye-based image, and thereafter jetting over at least a portion of the dye-based image a clear ink overcoat including a transparent polymeric binder containing dispersed inorganic nano particles, wherein the median equivalent circular diameter of all of the dispersed inorganic particles is in the range of 1 to 500 nm. Color fade due to ozone effects is diminished while maintaining jetability.
