New Epson R1800 Problems?

I just bought the Epson R1800. After printing out a couple of portraits on various types of Epson paper using the correct ICC profiles, I quickly noticed that when I look at them under certain lighting (especially flourescent), the faces turn "bronze" in the glare of the light. Is this normal or is it "bronzing"?

After printing with "Best Photo" and "Photo RPM" some of the previous described problem fixed itself on small photos. However, when I print on "Luster" paper, with larger photos, such as 5 x 7's or 8 z 10's, I still notice that the photo changes color in the glare of the lights, especially flourescent lights - skin changes color the worst - it becomes a yellowish bronze color. I didn't have this problem with my Canon using dye inks. So pigment inks change color under the glare of the lights and is this something I have to live with? Or am I doing something wrong?

Not all pigment inks do this. The new K3 inks are supposedly better. I've no experience with this as I use the outstanding R2400.
