Similar problem as found in this thread: http://forums.autodesk.com/t5/AutoCAD-2013/Quality
I'm using a PDF overlay which looks perfect in CAD and print Preview. When printing to PDF the quality drops to a level which is useless. I have tired increasing DPI and Quality settings but the outcome is the same. Please take a look at the pictures any advice would be appreciated.
Print Screen Of Print Preview - Notice Quality of text on the panel
Print Screen Of Actual PDF - Text unreadable...
EDIT-- It seems I can't upload an image big enough to show the issue. You'll have to take my word for it.

It depends on the size of the pdf. Lets say I have an 11x17 pdf of a football field. When I place it in my drawing and scale it to be real size, the yard markers are going to be very blurry. If I have an 11 x17 pdf of a pencil and repeat procedure, the drawing will print the #2 Ticonderoga label very well.
A "D" size pdf will be clearer in your drawing than the "B" size pdf after scaling to real size.
Sometimes though you have to break the rules of CAD drafting if the results of your drawing depend on the image quality of the pdf. You may have to half or quarter size your drawing so the scaling of the pdf is minimalized. I used to "Have" to do this with certain pipelines which were over 5 miles long and I only had a Plan View pdf and not section pdfs of every few hundred feet.
Plus, printing a PDF to a PDF is essentially sampling an image to create another image rather than copy-clipping the PDF content directly into another PDF. There will be a gradual degradation of quality.
I thought with the PDF being created from a vector and CAD seeing it as such (I can snap onto lines within the PDF) that it would not degrade. Its perfect in CAD its perfect in Print Preview but there is a massive loss of quality once printed. I'm wondering if there is a hidden DPI setting i'm missing somewhere?
It will do it from official Adobe and Cute PDF or even from CAD. If I use an raster or Vector image as an underlay (or even a screen print from the print preview of CAD) rather than a PDF it looks better. This shouldn't be the case. It not even an overly complicated drawing as you can see.
Do you have the same problem when plotting a drawing file to PDF using the DWG to PDF.PC3 or is it only when you have a pdf underlay to pdf?
No it plots to PDF perfectly fine. All items within the PDF look fine except the PDF underlay. The PDF is perfect quality on screen and in prevews its only when actually plotted.
Have you modifed visual styles in this drawing? Try the following:
In model space set the visual style to 2D Wireframe
In the layout (if used), make the viewport active and verify that it is set to 2D Wireframe
Select the viewport frame, in the Properties palette ->> Misc ->> Shadeplot. Set this to "As displayed', if that makes no difference try, 'Legacy Wireframe".
If you don't see a difference can you post some sample files? Be sure to remove sensitive data.
I wanted to check back to see if you had everything working as expected or if you would be able to post some samples? Thanks!
