Line features from a map image layer are blurred and jagged when the PrintingTools service is used to export a PDF.

Workaround

• For a high-quality PDF, use ArcGIS Pro to export the same map image layer(s) and layout with “Output as Image” option enabled. In this case, user does not need to use PrintingTools service. Refer to the following documentation for additional information: https://pro.arcgis.com/en/pro-app/latest/help/sharing/overview/pdf-export.htm

• If the default or custom PrintingTools service in a web app is used, add the map service sub-layer directly to the web map as opposed to the map image layer.
