I posted this in September: "Over the past week, I have received pdfs from 2 different graphic design contractors that do not open correctly in Acrobat 9 Pro. There is an error in the document and when I scroll to the page where the error is, I get: "An error exists on this page. Acrobat may not display the page correctly. Please contact the person hwo created the PDF document to correct the problem." I did this, and the contractor remade the pdf 3 times, and I still couldn't open it. This contractor is already using CS5. For the problem today, I haven't asked for it to be remade yet--decided to see if I could find out if anyone else is having the same problem. The second contractor is using CS4. The only thing that I have done differently at my end over the past week is upgrade CS4 to CS5. I already had Acrobat Pro 9 so I didn't update it when I updated my CS5 products. Should I have upgraded Acrobat 9 anyway? Somehow, it doesn't feel right that this is the problem. Any info on this would be appreciated."
I got one response from that posting, suggesting that the pdf was corrupted over email. That wasn't the problem.
What I didn't say above is that whenever I got an error message upon opening the pdf and clicked OK, I got another message: "Insufficient data for an image." I found that one or all of the images in the pdf were missing. Upon further investigation, the contractor and I found that sometimes the error message pointed to a specific font used--that being a Helvetica Bold font. Once we substituted it with a Helvetica Neue LT Std Adobe Opentype font, we no longer had an issue.
However, the problem rose it's ugly head today--what, 6 months later! I'm talking about 2 different pdfs this time.
For PDF#1, I got this error message about the font: "Cannot extract the embedded font 'JNAGNS+HelveticaNeueLTStd-Bd'. Some characters may not display or print correctly." When I click OK, I get another: "Insufficient data for an image." The images don't show up in the pdf. What I don't understand about this pdf is that this is one of those that was fixed in September. The only changes made in the document was to paragraph text--none to the text in the images. When I opened the revised pdf today, I am getting the same message again. This makes no sense.
I returned to my September blog to see if any further advice had been posted, but nada--not even anything from Adobe about it. I goggled until I found where someone suggested running a "Report PDF syntax issues" analysis in Preflight. I did that and even though the analysis showed the pdf passed, I checked the fonts in the list and saw that the one pointed to in the error message showed that a long list of glyphs were missing on both pages of the pdf. I have asked my contractor to replace her font with a new one, in case it has gotten corrupted. Haven't a new pdf to open yet.
Then when I opened PDF#2, I got the message: "An error exists on this page. Acrobat may not display the page correctly. Please contact the person hwo created the PDF document to correct the problem." When I ran the "Report PDF syntax issues" analysis in Preflight, I found got this warning: "Invalid operand(s) for operator (1 match on 1 page)". I clicked through and under "Page Description Errors/Invalid operand(s) for operator", it identifies Operator Name, Stream State, Operators Read, and Traversal Path. Under "Trigger Values" is says "Invalid operand(s) for operator: is true". None of this means a thing to me so I can't figure out what the problem is.
Let me say this: Both the contractor and I are using CS5 and Acrobat Pro 9, on Lion. If it helps, the contractor also sent one of the problem pdfs back in September to my boss who is running Acrobat Pro 9 on Windows 7 and she got the same messages.
Does anyone out there have a suggestion for us? PLEASE HELP!!!!
