Revit to pdf solid colors disappearing

[Anonymous]

Solid color patterns are disappearing (from solid grey to transparent ) just in some areas. when I press on preview it shows perfectly fine but when I print it to pdf the issue above happens. 

When I switch to Raster printing seems like the issue is solved but the graphics are not as good as Vertical printing.

 I tried same file on different computer, no issues. Seems like its only happening to my computer !

I added a picture, You can see the highlighted area with blue is suppose to be solid grey.

any suggestions ?

Option 1. Print with raster and set the quality to the highest. 

Option 2. Ask your colleague to print it for you. 

Option 3. Try different PDF printer. 

Option 4. Use white instead of grey. 🙂

Thanks for your suggestions. But im not looking for a workaround. I would like to solve this issue so I can print from my own computer.

Are you using the exact same PDF printer?

Yes. I tried multiple pdf readers, same issue.

Option 5. Try different approach. Eg. If it was filled region,  try color scheme, or material hatch.

Does he do the same in the preview or when you print to a normal paper printer?
