[NTG-context] color (rendering) intent

[Henning Hraban Ramm]

Hi,
in http://wiki.contextgarden.net/Context_2009.10.27#Data_files
there’s:
	• new parameter for \setupcolors: intent=none|overprint|knockout

I had \setupcolors[intent=overprint] in my environments, but since a few betas, I get „overprint“ printed on all pages, messing with the layout.
Now I changed this to \setupcolors[intent={Uncoated FOGRA29 (ISO 12647-2:2004)}], and it works again. As far as I can see, it doesn’t change anything, I find no color intent mentioned in the PDF.

The color profiles are listed in http://wiki.contextgarden.net/PDFX for \setupbackend; intent in \setupcolors is not documented.

Can you shed any light on that?


Greetlings, Hraban
