I have another question.
The print shop wants the background image to be overprinted. Is it
sufficiant to set »overprint=yes« once in \setupcolors or does one need
to explicitely tell the region with \startoverprint ... \stopoverprint?
simply use \startoverprint ... \stopoverprint for the text regions. you
may need to add \startknockout ... \stopknockout for picture elements in
that region. the "overprint=yes" option is for document wide setting, so
this is not what you want.
anyhow, if you own a copy of acrobat, you can visualize the overprinted
elements in the output preview (color warnings).

A minimal example:
% \startminimalexample
\setupcolors[state=start,cmyk=yes,rgb=no,overprint=yes]
\definelayer [mybg]
[x=0mm, y=0mm,
width=\paperwidth, height=\paperheight,
repeat=yes]
\setlayer [mybg]
[hoffset=5cm, voffset=7cm]
{\externalfigure[sample/hacker.jpg][max]}
\setupbackgrounds[page][background=mybg]
\starttext
Is this sufficiant for overprinting?
\dorecurse{4}{\input tufte\par}
\page
\startoverprint
Or does one need to explicitely tell context the region?
\dorecurse{4}{\input tufte\par}
\stopoverprint
\stoptext
%\stopminimalexample
Thanks again,
