I was sent a PDF that when I open it on Illustrator, it inverts the colors on the image. The image is embedded, in the Links panel its say NA for format. The file was originally created in Flexi, which I assume is the issue, I just want to know what and why. My solution was to simply invert them back. Here what's weird... The thumbnail preview in Finder display the color correctly, it's when I open it on Illustrator that they get inverted. Tried Photoshop, same thing, preview displays as it should, when opened it inverts them. If I open it as a PDF in Reader, it displays just fine.

The answer to your question is simple. Opening PDFs in Illustrator that were created in other applications can cause strange things to happen. Why? Illustrator is NOT a PDF editor. If you want to edit a PDF, try the editing features in Acrobat DC.
Here's a video tutorial about these features: http://www.jeffwitchel.net/2015/08/edit-pdfs-like-never-before-in-acrobat-dc/
I am aware of that. I did not imply Illustrator is a PDF editor, I am aware the PDF created in Flexi is the issue. I was asking why, more specifically, the technical reasons were this can be replicated. This customer doesn't get it, and while I would love to tell them to stop using Flexi period, that isn't an option. I've had my share of weird files and this was a first to me so thought I can give them a better answer than "your file doesn't work with my program, send me something else" since EPS is what I asked for in the first place. I hate PDFs when sent for printing for this reason. This job came and went, but I was curious anyways.
I'm with Jeff, Illustrator is not a PDF editor.
First try view >> overprint preview
Then try File >> Document color Mode >> change CMYK to RGB or visa versa . PDF can have both document colors modes in the same file.
Hi everyone, this is the easiest way to fix this problem super quickly. 😉
Hope y'all find this helpful!
Stay safe! ❤️
Your video does not solve the issue in this thread.
Actually Adobe illustartor IS a PDF editor, you can create multi page PDFs, import and export. I am having the same problem. None of the commets here have solved this. The only thing I can think of that works is to export as high resolution jpgs then re-import, but that makes in undetiable.
No, Illustrator is not a PDF editor.
PDF is not a native file format - PDFs can just be imported, which in turn means that Illustrator converts the PDF's data structure into its own structure. A couple of object Illustrator doesn'teven understand. And what you experience is probably caused by either image formats or color profiles that Illustrator doesn't fully understand either and then ignores or converts badly. This effectively ruins the PDF.
And if you don't believe us then maybe you believe the people who are responsible for the PDF file format at Adobe (and have been for the last ~20years and thus know the format better than most people in the industry) : https://prepression.blogspot.com/2014/09/the-ten-commandments-of-pdf.html
There has been a long time issue with Illustrator, when exporting to screen as jpg from a CMYK document.
Instead of converting it to SRGB as Ps does, it exports it as cmyk jpg and colors appear inverted.
Has there been any resolution to this issue at all?
The most simple way is opening the PDF in Photoshop and save it in Press Quality in cmyk mode.
After this Illustrator shows the color in the images the right way. (not negative)
