Digital BW, The Print

i downloaded the free trial of PixelGenius PhotoKit 1.1, and printed out a 
Medium Format photograph on my 1280 with OEM inks, using the 'Platinum' action, 
on Matte Paper Heavyweight, and i was quite pleased with the result

BUT: when held under Daylight, the image has a distinct green tone to it, 
while under household lighting, it looks fine

does anyone know what causes this, and how to 'fix' it?

my next test will be to use Premium Glossy Paper, and hopefully there will be 
no strange Magenta/Green cast, but i am not holding my breath just yet :)

What you describe is called metamerism. It is an ongoing problem with the Epson Stylus 2200 which uses Ultrachrome pigment type inks. 
The solution that some have been using is called a RIP. It is special software that basically neutralizes the problem by taking some of the cartridges out of the printing process, I think.  Anyway, people claim to be getting much more neutral tones. I own a 2200 also and do not have that software and have the problem. My solution has been to convert the image to RGB and then color correct by adding a little magenta. In my system, I add 5 magenta. Prints then look pretty good in daylight and very slightly magenta in tungsten. It's a temporary cure that isn't perfect.  You can buy a RIP from various vendors but they are expensive. They can run $495 and it is best if you build or buy profiles for your system. You would need a monitor calibration device for that. I'm resisting going there myself as I do this for fun and a little profit.
If you wo
uld care to pursue this further, check the Epson Stylus 2200 printer group. It's a big topic of discussion.
