I'm at a loss how to overcome this. Spent almost a whole day, together with another person, trying to fix it with no success!
I use Adobe pro CC on a PC
I usually receive pdf files from this one client who edits and formats a book in Mac Pages. Up until a few days ago I had no problems converting the client's pdfs into pdf/x3, but the last three versions of the latest file have stumped me.
Just to test, I first just tried to convert the file (33MB), unchanged, to pdf/x3 using the save as other option - message reads "the document has been saved, however, it could not be converted according to the selected standard profile: convert to PDF/X. Please use preflight with the profile "Convert to PDF/X" in order to identify those properties of the document which prevent it from being compliant to this profile"
if I then choose under Profiles - convert to PDF/X3 - it says no problems found, and appears to have saved the file. If I try to save again as a pdf/x3, just to make sure, it then tells me it's not pdf/x3 compliant
OK - so then I go back to preflight - and choose the standards function - then pdf/x3, then continue with the default colour profile. About halfway through the conversion, at the point of saving the file, I get the message "unable to save the pdf file after post processing"
So far I've had no luck figuring out what this is.
I then choose the option of "verify compliance of ppdf/x3" - message reads "pdf/x3 version key (GTS_PDFXVersion) missing", and "Trapped key not true or false"
Help!! How can I be sure the file converted / or not?
