I'm trying separate the channels of an image like this: http://en.wikipedia.org/wiki/File:Barns_grand_tetons.jpg , so that all black and gray color data lies on one plate http://en.wikipedia.org/wiki/File:CMYK ...

Promote greys to cmyk black?

Is there a way to move all gray colors of a CMYK image (e.g. a cmyk .tiff) into the black (K) plate with Imagemagick?
(In Adobe Acrobat Pro, this functionality is labeled: "Promote grays to CMYK black")
