Re: PDF export bug (or maybe not, depending who you ask...)
I would agree with Mike here and what has been written in the Illy forum is that if you have this problem and that you have CS4/5 then all you have to do is to remove the masks and re-save easy. Also if you use PDF/X-a or X-3 in the Advance tab under the export filter in D Pro you will produce a more reliable PDF. The problem which may happen after that is you might increase the number of clipping masks but if you have any copies of illy that will be solved on the re-save once you have deleted the unnecessary clipping masks. Hope that makes sense to you. You cant expect that a file made in one programme will be able to be edited exactly in the same way in another as they all have different ways of rendering this even happens when I try to open a file which has been made in CS 5 when I have only CS 3.
