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