linux - Ghostcriptでpdfをpdfaに変換できません

Question

centos で「pdf.pdf」ファイルを変換しています。

gs -sDEVICE=pdfwrite -dNOOUTERSAVE -dNOPAUSE -dBATCH -dPDFA=1 -dUseCIEColor -sProcessColorModel=DeviceCMYK -sOutputFile=out.pdf PDFA_def.ps pdf.pdf

私の PDFA_def.ps は次のようになります。

[root@localhost Downloads]# cat PDFA_def.ps 
%!
% This is a sample prefix file for creating a PDF/A document.
% Feel free to modify entries marked with "Customize".

% This assumes an ICC profile to reside in the file (ISO Coated sb.icc),
% unless the user modifies the corresponding line below.

% Define entries in the document Info dictionary :

/ICCProfile (/usr/share/ghostscript/9.07/iccprofiles/default_cmyk.icc)
def

[ /Title (MyTitle)                  % Customize.
  /DOCINFO pdfmark

% Define an ICC profile :

[/_objdef {icc_PDFA} /type /stream /OBJ pdfmark
[{icc_PDFA} <</N systemdict /ProcessColorModel get /DeviceGray eq {1} {4} ifelse >> /PUT pdfmark
[{icc_PDFA} ICCProfile (r) file /PUT pdfmark

% Define the output intent dictionary :

[/_objdef {OutputIntent_PDFA} /type /dict /OBJ pdfmark
[{OutputIntent_PDFA} <<
  /Type /OutputIntent             % Must be so (the standard requires).
  /S /GTS_PDFA1                   % Must be so (the standard requires).
  /DestOutputProfile {icc_PDFA}            % Must be so (see above).
  /OutputConditionIdentifier (CGATS TR001)      % Customize
>> /PUT pdfmark
[{Catalog} <</OutputIntents [ {OutputIntent_PDFA} ]>> /PUT pdfmark

そしてエラーが発生します：

[root@localhost Downloads]# gs -sDEVICE=pdfwrite -dNOOUTERSAVE -dNOPAUSE -dBATCH -dPDFA=1 -dUseCIEColor -sProcessColorModel=DeviceCMYK -sOutputFile=out.pdf PDFA_def.ps pdf.pdf

手伝って頂けますか？現在、いくつかのメタデータなしで、pdfをpdfaに変換する必要があります。
