Hello,
I am trying to embed a profile but it doesn't work. I am using:

\setupbackend
    [format=PDF/X-1a:2001,
    intent=Coated FOGRA39 (ISO 12647-2:2004),
    file=CoatedFOGRA39.icc,
    option=always
    ]

Acrobat Preflight says it has not profile embedded. Am I doing something
wrong?

The next thing is I am using text smaller than 12pt and nothing helps me to
prevent ConTeXt to:

1) overprint the GRAY text (\setupcolors allows just to set cmyk-gray/rgb);
2) knockout text smaller than 12pt, what is not allowed in a good pdf file.

Any solutions highly appreciated, Jan Hejzl
