It's not always convenient to systematically convert grayscale images to CMYK on output.
In Prinergy, for instance, the ProcessTemplate's output DeviceLinkProfile (if that's what's being used) *has* to be GCR in order to get GCR-kind of conversion.
It has pros and cons.
Personally, I decided against systematically converting grayscale images to four-color images for jobs.
If a customer wants GCR "grayscale" I'll gladly supply a heavy-GCR ICC output profile for converting in Photoshop.
Depends on the job...

Hi,
When placing a black-and-white photograph in a page that will also have plenty of other photographs, illustrations and layout elements in color, part of a magazine that will be printed in offset, is there a rationale for preferring that gray values of that photograph are printed using only black ink or with a mix of all CMYK inks instead?
The particular CMYK combination I mean is the one I would automatically get in the likes of Photoshop by converting the grayscale image to the target CMYK color space using ICC profiles.
