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.

fixed in beta

Thank you! So I can document that key for \setupcolors? (Does it do anything? Different from \setupbackend?)

it should add some group info in the pdf

If I remember correctly this sets the complete document (global) to 'overprint' (or 'knockout'). Only useful for grayscale only documents. Don't set this parameter, if you want to use local overprinting (or knockout)! There should be a warning about this in the documentation. The \setupcolors setting is also far older than the PDF/A|X related output 'intent' parameter in \setupbackend. No direct relation other than that both parameters are prepress options.
