I too am experiencing the same issue. Didn't have the issue with CS5 at all so I feel it may be isolated to the CC Collection. Like you mentioned, every other compression format worked except for HIGH so from my thinking, it may have something to do with how photoshop compresses the HIGH setting that gives it an unreadable file. So I feel like it may be more than likely a fault with Photoshop. Hopefully someone can provide an answer as I would oftern use HIGH compression to save my PDF's
I have a detailed analysis, not a solution, based on the 500 x 500 file posted above.
Adobe Acrobat X cannot read the file
Acrobat cannot decode the compressed data that makes up the image
Chrome can display the PDF
I extracted the JPEG data and tried to use it in a variety of ways
- Photoshop 7 failed (no useful message)
- Chrome worked
- Distiller gave the most interesting error: HuffTable exceeds 12 entry limit
A Hufftable is a normal part of a JPEG, and it is 16 entries in this file. Never mind what
My guess: for best quality, Photoshop now uses a bigger "Hufftable", but nobody
in the Photoshop team thought to tell the rest of Adobe's developers that they
would need to change their code! Even if they did, there is no good reason to
be making PDFs unreadable with old versions of their sofware.
Another observation for what it is worth (not a solution again). I was able to open all 3 PDFs in Irfanview as graphics. The properties of the image were
The major changes for the others within the JPegs was the number of pixels (133X133) and the size (1.4inX1.4in). There is also a reduction in the number of colors.
Just for information, I opened the big JPeg in Acrobat (9.5.5) and it opened fine. However, it looks like the color space was changed as shown below:
Even if I change the input to use CMYK and not RGB, it looks like it gets converted to RGB. I haven't spent time to figure out the preflight analysis properly, but at least this may give you some info back.
I'm glad I'm not crazy. Thanks for the error confirmations on other systems, and thanks for posting the extra in-depth information, guys! I'm hoping that either the Acrobat or the Photoshop team can address this quickly. Of course, to me it seems like a simple error to fix, but I'm sure there's more to consider from Adobe's perspective. Still, every time I see a product update that doesn't cover one of these programs, I die a little inside.
Are there any tricks we, the users, can do to fix the program error? In my case, saving everything in 'maximum' quality creates file sizes that are 3x larger than on 'high' quality. Already have a few bounced emails because of that. First world problems, I suppose.
Well, this is not good. It's been a few months without an update or word from the adobe team on either this topic, or the one posted in the Photoshop forums.
I have gone through several Photoshop updates over this time - none of which addressed this issue.
Having to rely on an older version of Photoshop (CS6) to perform the simple task of exporting every PDF is quite frustrating, and quite silly to begin with. I'm sure we'd all appreciate some sort of response to this one. It seems like a simple fix for someone deep in the code. There shouldn't be any functional difference for saving PDFs in Photoshop CC vs saving them in Photoshop CS6.... or at least not one that creates corrupted files.
