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

This should be done automagically in pdfTeX (at least it once was).

Re: [NTG-context] PDF/A with ConTeXt
2008/2/7, Santy, Michael [EMAIL PROTECTED]: Records management systems prefer to receive their PDFs compliant with the PDF/A standard (subset of PDF 1.4). Is there any mechanism in ConTeXt/pdfTex to specify the PDF output should comply with PDF/A? There is no single switch. PDF/A-1b is doable, -1a probably needs future extensions in the engine (tagged pdf). Both need other software to check the images.
