Ghostscript 9.07 : PDF/X-1a:2001 : PDF/X输出意图缺失

Question

请您告诉我如何嵌入PDF/X输出意图。当我检查飞行前，我报告说PDF/X-1a:2001 : PDF/X输出意图在PDF文件中缺失。

PDF文件中遇到的问题：

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指挥部：

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

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/ISOcoated_v2_300_eci.icc)   % Customize.
def

[ /Title (Title)                  % 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 (ISO Coated v2 300% (ECI))      % Customize

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

Answer 1

在gs命令中，指定PDF定义文件PDFA_def.ps。您需要指定PDF定义文件。

Answer 2

Ghostscript目前不支持PDF/X-1，只有PDF/X-3，PDF/A-1和PDF/A2。目前还不可能将所有颜色定义转换为PDF/X-1所需的颜色空间。
