(Cross-post from the Photoshop forum, where I was asked to post in the Acrobat forum: http://forums.adobe.com/message/5553829 )
When I save a PDF file in Photoshop CC in CMYK color with JPEG compression (quality = high), it will save without any errors. However, when I open the file in Acrobat (11.0.3), I get an "Out of Memory" pop up error. I press Ok, and the document is just displayed as a blank white image.
I'm using Win7 64-bit, Photoshop CC 64-bit. Plenty of memory (24GB) and allocated RAM in preferences, and I've done some troubleshooting that leads me to believe the error is not due to system memory, but rather a specific bug in the software. I have Photoshop CS6 on the same machine, and if I open the PSD, save as PDF with the above settings, everything is fine when I open it using Acrobat. This seems to just be for Photoshop CC, not CS6.
Here is the troubleshooting I've done so far:
PDF format, RGB color, any other settings --> Acrobat can open the file.
PDF format, CMYK, no compression --> Acrobat can open the file.
PDF format, CMYK, JPEG compression [medium] --> Acrobat can open the file.
PDF format, CMYK, JPEG compression [high] --> Acrobat can NOT open the file because it encounters the "out of memory" error.
PDF format, CMYK, JPEG compression [maximum] --> Acrobat can open the file.
This is silly. I don't get it. Can anyone else confirm this problem for me?
Like you said, there isn't enough information to rule out an issue with Photoshop CC, as the same action using Photoshop CS6 results in a usable file.
New information (while making files for uploading):
The error only occurs with CMYK files of larger dimensions. On a 500x500px image, Acrobat throws out "A drawing error has occured". a 2500x2500px image runs into the "Out of memory" error. In either case, Acrobat cannot successfully open the file generated by Photoshop CC, while it can if it was made using Photoshop CS6.
