I've come across a weird problem with exporting a PDF from InDesign file.
My collegue exported part of his design in InDesign (he works on Windows), this is a screen from the original file (taken on my Mac, but it looks the same on his PC):
This is a comparison of how the file looks on his PC and my Mac:
We both use the same export profile to preview our work, downscaling bitmaps a little, and converting whole thing to adobe RGB color profile. We use it to send lightweight files to our clients for proofing. It always worked fine until now.
I'm baffled. I've never seen PDF behaving like this before. If it was corrupted or damaged, it still produced the same results everywhere, I mean that's the point of PDF after all.
Can anyone explain what is happening?
