I have the same background applied to 2 different Master's. All the pages print perfect except for Page 12-13. I have made sure that both Masters were not applied to the spread. It is showing that Master 1 is applied to pages 1-11, and Master 2 is applied to 12-32.
However, when I print, Page 12-13 looks like it's at 100% opacity, instead of 60% like the rest of the pages. I will admit, In Design is not my preferred program, but I feel I know it pretty well.
I have deleted all Master's twice, made them again, and reapplied. It is still not fixing the issue. Does anyone have any suggestions?
