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 Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
