A client who absolutely, no questions asked; wants the final printed sheet to match a proof (Epson) when viewed in his office. The office uses fluorescent lighting (F11, F12 - don't know). According to the client it is being done by a printer. The client supplies the Epson proof to the printer; the printer prints and somehow the two are supposed to match each other when viewed together in the office. Does the printer make an internal proof based on the office lighting and prints to that ??? I can think of numerous scenarios; all of which seem to be a rather large pain. Mike Stewart

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.

Relevant indeed, and very funny because it's so true and close to home. I'm reminded of the high level corporate executive with a 2x3 ratio 35mm slide who demanded that I make him a square print without cropping anything at all. When I told him it couldn't be done after going through several examples of reality testing, he threw his hands up in disgust and left saying, "I don't care how you do it, just do what you're told, you're the expert." -----Original Message----- From: Ben Goren Sent: Friday, January 23, 2015 12:49 PM To: Mike Stewart Cc: colorsync-users Subject: Re: lighting question _______________________________________________ Do not post admin requests to the list.

Back in the 1950s a deceased cousin was a manager in the Eastman Kodak Information Gallery in Grand Central New York. A client came in asking why the scene was always appearing upside-down on the ground glass of his Graflex, and even when he rotated the camera 180 degrees the image would not correct. My cousin explained to him about how the light rays pass through the lens, so no amount of rotating the camera would "correct" the issue, to which the client responded that "you have to be the most stupid person I've ever met". :-) Mark From: John Castronovo <jc@technicalphoto.com> To: colorsync-users@lists.apple.com Sent: Friday, January 23, 2015 1:54 PM Subject: Re: lighting question Relevant indeed, and very funny because it's so true and close to home.

Be sure your client understands that by jumping though hoops to make sure the print matches the proof under his office lighting conditions, there stands a reasonably good chance that it may not match anywhere else. Depending on the context and use of this material, that might mean something. Oh, irrational people. Brian Pylant Electronic Prepress / Color Management Disc Makers Pennsauken NJ
