Hi,

a quick description of the PDF/X interface for all testers. More
documentation in the (hopefully near) future.

\setupbackend
  [format=valid pdf/x name,
   profile=name.icc,
   intent=name.icc,
   level=compresslevel, % default 3
   file=optional specification file,
   option=always|never]

The following two parameters are sufficient for most cases.

'format':
    currently supported versions:

      'PDF/X-1a:2001'
      'PDF/X-1a:2003'
      'PDF/X-3:2002'
      'PDF/X-3:2003'
      'PDF/X-4'
      'PDF/X-4p'

'intent':
    sets the output intent

    the name of the predefined output intents can be found in
    <tex-path>/texmf-context/color/icc/context/colorprofiles.xml

    more info about this collection under
'http://www.gwg.org/120.387.0.0.1.0.phtml'
    All profiles will be available on the Wiki soon.

      'Coated FOGRA39 (ISO 12647-2:2004)'
      'GRACoL2006_Coated1v2.icc'
      'ISO Coated v2 300% (ECI)'
      'ISO Coated v2 (ECI)'
      'ISOnewspaper26v4'
      'ISOnewspaper26v4_gr'
      'ISO Uncoated'
      'ISO Uncoated Yellowish'
      'ISO Web Coated'
      'Japan Color 2001 Coated'
      'Japan Color 2002 Newspaper'
      'Japan Web Coated (Ad)'
      'SNAP 2007'
      'SWOP2006_Coated3v2.icc'
      'SWOP2006_Coated5v2.icc'
      'Uncoated FOGRA29 (ISO 12647-2:2004)'
      'Web Coated FOGRA28 (ISO 12647-2:2004)'
      'PSR_LWC_PLUS_V2_PT'
      'PSR_LWC_STD_V2_PT'
      'PSR_SC_PLUS_V2_PT'
      'PSR_SC_STD_V2_PT'
      'PSRgravureMF'

These parameters are kind of special.

'profile':
    sets the default color space profile (option for color management);
    see pdf-x4p.mkiv for an example; currently only one profile per
color space allowed

'level':
    set the PDF compress level (normally not needed, more an option for
testing)
    You can easily break PDF/X compatibility with a wrong value.

'option':
    'always': force embedding of the output intent profile (useful only
in case of PDF/X-1a)
    'never': don't embed the output intent profile; also just a test option.
