Is this a gamut problem?

I have a digital photo of a girl in a red dress. I made some minor brightness and contrast adjustments. It looks fine on screen but when printed (Epson 1280) some area print a siclky green rather than the proper color. This is some small dark areas (corners of mouth) and some areas of the red dress.

This is in RGB mode. When I turn on Gamut Warning there’s a partial correspondence between the gamut warning areas and the green areas. In CYMK mode there are no gamut warnings.

What’s going on?

Interesting. I have had the darker areas go red or blue but never green (at least not yet).

First of all, which RGB profile? Which CMYK profile?
It seems from your description that you have an RGB color which is well outside of the CMYK profile.
You can try altering the RGB colors until the gamut warning goes away. Another thing is to review the monitor profile, the working space profile, and the printer profile.

I am using Adobe RGB (1998) for RGB and US Web Coated (SWOP) v2 for CYMK.
