Black elements disappearing when opened on another computer.
Hi guys,
I'm not entirely sure if this is an Illustrator question, as it relates to the PDF which is exported from Illustrator.
The problem I'm having is that an Illustrator document created on a specific machine one of my employees works on always has massive issues with the way it handles black elements. On that machine, it's fine. It looks fine in Illustrator, it looks fine on the PDF export, but if I open the file on MY computer, although it looks fine in Illustrator, all of the 100% black elements just magically disappear in the PDF. Even if I open a PDF file which has been exported from the original machine on my computer, same result, no black.
Both machines are running the same version of Acrobat and Illustrator.
I can't figure it out, but I deduce that it must be something to do with the way the original file is being set up. I've checked the overprint settings, blend settings, everything I can think of, I just can't figure this out.
This is an image of what the result looks like (the black in this image is only appearing where there is a mask for the image above it, you'll notice that the black in the barcode has also disappeared):

Anyone got any ideas?
TIA.
