Export quality issues when exporting drawings with inserted PDFs

[Anonymous]

Hello All,

I've been having issues for months now trying to export drawings that contain inserted PDF images. Typically this occurs with grading/site plans or USGS topographic maps, but particularly the former. I've had this issue accross 2018 and 2022 autoCAD now and have wasted more hours than I want to admit playing with export settings in an attempt to get something good. I figure now it's time to turn to the professionals!

This the drawing when exported as a PDF

This is the drawing when plotted using the print function to Adobe PDF. Quality settings high and DPI 1200.

This is the drawing when plotted and printed to adobe PDF. Quality settings are high and DPI set to 1200. White boxes have been placed after the fact over project information in the bottom corners. 

Lines are set to overlap, rest of the settings are below

This is screenshot of my layout view.

Currently running AutoCAD 2022 on windows, but it's on a laptop without a dedicated GPU. I'm hoping it's a settings issue (I'm self taught on CAD, and relatively inexperienced) and that maybe some can help me, but my fear is this might be a hardware limitation. Any and all help is appreciated!

Have you tried "AutoCAD PDF (High Quality Print)" or "DWG to PDF" virtual printers instead of "Adobe PDF"?

DWG to PDF yields the same results as exporting, only it takes 3 times as long. I'll try AutoCAD PDF right now and let you know the results.

Same results as regular export.
