%%% overprint.tex
\nopdfcompression
\setupcolors[state=start,rgb=no,cmyk=yes,overprint=yes]
%% to be sure
\definecolor[CYAN][c=1.0,m=0,y=0,k=0]
\definecolor[MAGENTA][c=0,m=1,y=0,k=0]
\definecolor[YELLOW][c=0,m=0,y=1,k=0]
\starttext
\framed[background=color,backgroundcolor=CYAN,
frame=off,offset=.25cm,strut=no]{%BEGIN
\startcolorintent[overprint]
\framed[background=color,backgroundcolor=MAGENTA,
foregroundcolor=YELLOW,
align={lohi,middle},
frame=off,width=2.5cm,height=2cm]
{overprint \\ \startcolorintent[knockout]{knockout}\stopcolorintent}%
\stopcolorintent
\framed[background=color,backgroundcolor=MAGENTA,
foregroundcolor=YELLOW,align={lohi,middle},
frame=off,width=2.5cm,height=2cm]{knockout\\
\startcolorintent[overprint]{overprint}\stopcolorintent}%
}%END
\stoptext


$>gs -sDEVICE=tiffsep -dNOPAUSE -sOutputFile=z.tiff  overprint.pdf  -c quit

Then study z.tiff, z.tiff.Cyan.tif,...z.tiff.Black.tif  with use gimp.
