Hello,

whatever I try, I cannot get the overprinting right (checked in Output Preview of Acrobat). Even overprint-001.tex from the test suite (2020-09-19) doesn't seem to have it right (latest beta). What I'm missing here?

\setupcolors[intent=overprint]
\startTEXpage[offset=10mm]
\framed[frame=on,offset=10mm,
        background=color,backgroundcolor=darkgreen]{
%         \startcolorintent[overprint]
        \startoverprint
        text in black
        \stopoverprint
%         \stopcolorintent
        }
\stopTEXpage


Thank you,
Jano

Forgot to say, I've also tried to add
\setupcolors[state=start,rgb=no,cmyk=yes]
though I think, at least state=start isn't needed anymore.
It doesn't change the overprint issue.
