Ghostscript 9.07 : PDF/X-1a:2001 : PDF/X output intent is missing

问题

Could you please tell me how to embedded the PDF/X output intent. When I check with preflight I reported that PDF/X-1a:2001 : PDF/X output intent is missing in the PDF file.

Problem faced in the PDF file:

1) PDF/X-1a:2001 : PDF/X version is not PDF/X-1a:2001
2) PDF/X-1a:2001 : PDF/X output intent is missing
3) PDF/X-1a:2001 : Document trapped flag is Unknown
4) PDF/X-1a:2001 : Text object uses invalid characters (.notdef glyphs)

GS Command:

gs -dPDFX -dBATCH -dNOPAUSE -dNOOUTERSAVE \
   -sProcessColorModel=DeviceCMYK -sDEVICE=pdfwrite \
   -sOutputFile=GS_Test.pdf PDFA_def.ps Test.ps

PDFA_def.ps :

/S /GTS_PDFA1                   % Must be so (the standard requires).
/DestOutputProfile {icc_PDFA}            % Must be so (see above).
/OutputConditionIdentifier (ISO Coated v2 300% (ECI))      % Customize

/PUT pdfmark
[{Catalog} <</OutputIntents [ {OutputIntent_PDFA} ]>> /PUT pdfmark

回答1:

In your gs command, you're specifying the PDF-A definition file PDFA_def.ps. You need to specify the PDF-X definition file instead.

Detailed instructions for creating a PDF-X/3 document are available here.

回答2:

Ghostscript doesn't currently support production of PDF/X-1, only PDF/X-3, PDF/A-1 and PDF/A-2. It isn't currently possible to convert all the colour definitions into the required colour space for PDF/X-1.
