Hi all, I made a complex illustration for a poster with lots of structures, brushes etc. The exported Pdf shows a strange fogginess in some parts of the illustration in Apple Mail only – in Adobe Acrobat, in the app Apple Preview, the preview in Finder and when converted in Photoshop everything looks fine and the values seem to be o.k., too. However it is not only irritating me, I am afraid my clients may see the same effect in their mail programme, so I wonder what is the problem and how to get rid of it. Any ideas?
