The print has some ever-so-slight metamerism; it's a hint greenish in sunlight (similar to my Kodak grey card, but not as bad), and almost magentaish under some daylight-balanced fluorescent tubes I've got in the kitchen. I've never really noticed the metamerism before; I think the (very subtle) shifts in hue with previous profiles swamped it.
[ Nomenclature police: Metamerism is when colors with different spectral responses match. Metamerism failure is when colors that should match, fail to match. ] To have any significant impact on this you need to be able to play with the black in the print. Generally raising black levels improves neutral robustness under different lighting conditions. Often this is at the cost of a more visible screening and banding artefacts. light black and light light black inks help make this more palatable. You need a direct driver (RIP) and other tools to play this game though. cheers, Graeme Gill.
