With the sample below, the resulting PDF will crash MuPDF, Adobe Reader will show an empty page (though in a longer document it shows a message saying the file is broken and just few pages are rendered while the rest is blank), Evince will open the file and show the text correctly but will give the following errors in the terminal:
Error: ExtGState 'GSoverprint' is unknown Error: ExtGState 'GSknockout' is unknown ....
Rebeated several time.
Sample:
\setupcolors[overprint=yes] \starttext Hello \TeX. \stoptext
ConTeXt version 2009.08.13 and 2009.08.16
Looks ok here with last mkiv stable and luatex beta-0.42.0-2009071723 If you have a mkiv beta, maybe you need last luatex trunk from svn . # context --version && luatex --credits MTXrun | main context file: /opt/luatex/luatex-lunatic/minimals-git/tex/texmf-context/tex/context/base/context.tex MTXrun | current version: 2009.07.17 17:23 This is LuaTeX, Version beta-0.42.0-2009071723 The LuaTeX team is Hans Hagen, Hartmut Henkel, Taco Hoekwater.
