New Epson Printer

I've never heard of anyone reporting metamerism when printing color images.

Roy Harrington's Quad Tone RIP is an excellent product for printing metamerism free B&W prints.

Does having the percieved color balance shift a good bit when changing from flourescent to incadescent or daylight count as metamerism? I've had that happen quite often with 2200 prints. Theres even a subtle shift as the print dries over several hours.

Yes!

But you can expect that with conventional color prints as well.

This is where I get confused - when I view my 'analogue' platinum prints they show the same amount of shift as my 2200/qtr prints. To me this is just the paper reflecting back the colour of the light it's viewed under. I have seen metamerism in inkjet prints and it isn't really the same.

Our eyes are not really sensitive to metamerism with colored images, but pick it up instantly with monochrome images. All the Epson drivers, when using the UC inks, produce the metamerism problem when trying to produce monochrome. So for lineralized output and smooth color-cast-free and metamerism-free monochrome output, a RIP must be used. We just don't notice the "problem" in colored images. Unfortunately the RIPs available now, don't support the newest R800 and R1800 printers yet (even though the R800 has been out one year). The 2200 is well supported though.

The most common RIPs are QuadTone RIP and IJC/OPM.

Now for our silver and Alt process diginegs, all this may be a moot point if one is making colorized negs since these color casts won't make a big difference in our alt process prints. The above discussion is only critical if you are injet printing.
