decompose/Foreground as registration color

Could somebody explain here what the option "Foreground as registration color" in
colors/decompose means.
I can't get a clear idea of what this option does by browsing the Web and reading books.
Something about CMYK, black and printing?

Hi Julien,

this option was introduced with 2.4, so it might be that only a dev can tell what it is about. For me such questions solved most quickly at the #gimp channel on IRC.

Greetings,

Sorry, me again...

.... there is some tooltip on this option. In german it roughly says, that "if the option is activated, every pixel of the current foreground color will be black in each component of the decomposed images/layers. This is quite useful to have something like "crop marks" in every channel".
