Hi,
I have written up a question on TeX.SE:
http://tex.stackexchange.com/questions/135543/pdf-colour-space-and-context
Aditya mentioned that the problem with transparencies is that it is
likely a known bug with Adobe Acrobat Reader: "I remember similar
questions being asked in the past, and the conclusion was that it was
a known bug in Adobe Reader."
Has anyone else come across this issue and found a way to resolve it in ConTeXt?
I ran into what I think is a similar issue with LaTeX and was able to
resolve it using the following command in the preamble:
\pdfpageattr{/Group << /S /Transparency /I true /CS /DeviceRGB>>}
I have not yet tried to reproduce the problem in either LuaLaTeX or LaTeX.
\setupcolors[pagecolormodel=auto]
might help
in acrobat, when transparency is used, a different route is followed (at
least in the past) when rendering
also, rendering colorspaces might be adapted to the output medium so
it's a combination of colorspace, monitor/paper, calibration,
knockout/overprint, transparency groups, assumptions etc
in the end, a print on a proper device is the reference
