Hi,I have a problem with the pdf underlay printing. I have a rectangular viewport in paperspace showing the pdf underlay. If I print it to pdf, it looks good. It looks much nicer though if I clip the viewport to follow the border of the pdf underlay. After I do that and print again there are 2 horizontal light green/blue streaks over the drawing in the pdf. I use Civil3D 2012 and Adobe PDF for printing. Anyone knows what migh thelp ? Thanks.
