Lord help us. These Illustrator shadows/gaussian blurs are going to kill us all. We were just informed by a printer that they are seeing super fine lines all over the background spot color. We send them DSC2 files exported from ArtPro. They run it through Prinergy and convert it to a PDF. We zoom in to pixel level in ArtPro and cannot see these fine lines. We do see overlapping boxes if we select all, which seem to be the background color. The only thing I can figure is the shadowing added in Illustrator is causing a translation problem when importing into ArtPro. I am going to try to rasterize the shadows and if that doesn't help I will also flatten them to see if they will import intact and not cause this breaking up issue. If anyone has an idea please let me know.
