Original User: jwingateNever mind about this -- I figured it out. I had created some white ellipse shapes in the Layout View and some in the Data View. When I deleted all of the elements from the Data View, it did not delete the ones that were created in the Layout View. Interesting. After deleting them from the Layout View, the export to PDF and print both worked fine, even at max resolution. No more spots.If you're curious, I had created the ellipse shapes to cover part of the road centerline that was visible underneath the road name labels. The halo I put around the labels was not quite big enough to cover the centerline completely between some letters in the label, like when L & Y are next to each other. Anyway, I ended up removing the halos and simply drawing a polygon on top of the line underneath the label and coloring it white. Then I didn't have any issues with the halo touching the parcel boundaries either.Thanks to those of you who spent time trying to figure this out. Sorry for the rookie mistake!James Wingate
