A dozen commercially available high gloss photo papers were imaged on several wide format printers. It was found that the gloss of the printed image area is dependent on type of printer and ink used. Most of these media have a significant drop of gloss at 300 and 400 percent ink load, typically used for composite black. Although these photo papers are advertised as universal media, a significant gloss reduction is observed with some printers even for secondary colors at a 200 percent of ink load.
