I am exporting map to pdf using ArcGIS Pro at 600 dpi resolution. The exported map is coming with some thin colored lines. I tried to export same map to png it appeared fine.

Am i missing something here regarding export settings for pdf ?

I have an interpolated raster these lines are reflecting the colors of that raster.

When i un-check that raster then it prints pdf fine.

I cannot include complete map screen shot but i am including the area where i dont have data. See the green lines in image.

enter image description here

When i select these blocks and right click i get the option to copy image. Seems like different small images have been stitched to generate this pdf.

    Have you checked this question although it is quite different (thick lines appear not thin lines)? gis.stackexchange.com/questions/240124/…

  • No no, its not like this. I am editing the question to include image Commented Nov 13, 2018 at 8:46
  • Have you tried removing the raster from the mxd and then uploading it again? It seems like there is a corruption occurring then translating to pdf and starting with a newly added layer has worked in the past.

One of the issue is with the transparency of raster


Other issue is that ArcGIS Pro while exporting map to pdf do not have option to rasterize(ArcGIS Pro will get this in 2.3 version)


The solution of this problem is instead of sharing it as a pdf, Use the Print option print to file and while printing, Select Microsoft print to pdf. This results in rasterized map in pdf and it appears fine.

Update Now you have the option in version 2.3

This resolves the issue

    I'm using ArcGIS Pro 2.4.2 and this is still an issue. Thankfully the Print to PDF option works.

This still appears to be an issue in 2.8. The selected answer, Printing to PDF, is fine for users that do not need to utilize Python automation, but without an arcpy.mapping.PrintMap() parallel in ArcGIS Pro, this solution lacks some functionality.

A solution to this that also allows the use of ArcPy's layout.exportToPDF() is to set the base raster transparency to 0%. Then, create a polygon with a white fill that overlaps the entire area of interest, and set the transparency on the polygon layer. This seems to get rid of the grid lines.

This would not work well for multiple overlapping transparent rasters, however.
