A client who absolutely, no questions asked; wants the final printed sheet to match a proof (Epson) when viewed in his office.
The only way to do that sort of thing and retain sanity is to get a spectrophotometric recording of the actual light they're going to be viewing the prints under and build the printer profile using that illuminant. But the profile will _only_ be valid for that illuminant. In particular, a print for a fluorescent illuminant is likely to look peculiar when viewed under incandescents or sunlight. This also assumes the capture process is colorimetrically valid, which is no small assumption. And that the colors are within gamut, and so on. And you can quickly get into very deep water if the original has colors with any significant degree of metameric shifting (including fluorescence). And the paper stock has to match and.... I'll be honest: my first thought is that this is a client who first needs a crash course in color science. And if the client isn't interested in that sort of thing, you may well need to double or triple your rates, because they're likely to turn out to be one of "those" clients.
