The International Color Consortium (ICC) specifies a standard profile format and associated color management architecture. In the version 4 of its specifications, it adopted a Perceptual Reference Medium and an associated gamut (PRMG) for perceptual workflows. The goals of this change were improved interoperability and more pleasing results. In this paper we start evaluating the effect of using of the PRMG on the quality of printed images. A series of psychophysical experiments were conducted with a large set of sRGB images. A small number of expert observers found that they tended to prefer the quality of prints obtained via a v4 workflow when printing with a printing system having a medium sized gamut. However, when printing with a system having a gamut similar to the PRMG, they did not find any significant preference. They also found that the use of v4 led to a better consistency of the rendering of the prints when using two printing systems with different gamuts. None of the algorithms were strongly preferred by the observers of a larger panel.
