Additives are identified that greatly reduce the fade of dye-based images on porous media. A series of additives were topically applied to commercial porous media that was then printed on with commercial dye-based ink sets. Significant differences in dye fade were observed upon simple ambient exposure under office lighting conditions. Non-yellowing compounds were identified which significantly slowed the rate of color loss of the prints, provided even fade over all colors screened, and introduced no discoloration on unprinted media surfaces.
