We often ran 4C 'grey' images to have fine control over the tone/ warmth on press. This was facilitated by applying a fairly high level of GCR to the images, so we used cmy for fine-tuning and still allowed black to carry most of the image. Randy N

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.
