Funky Arrow Lines?

I assume this is a bug but wanted to check if anyone knows a way around it or if I'm doing something wrong.

 

Have a look at the attached picture of a detail dummy, all horisontal lines on the arrows seems to vary in thickness? The picture is a screen shot from a a pdf at 100%, this is the way it prints. (Don't worry about the line work on the actual detail, I just use this one as a template).

There is definitely a difference between the built-in 'Save as pdf' and using Adobe pdf as the printer driver, quite dramatic in fact.

 

I printed them out, both using 1200dpi, and compared side by side the built-in 'Save as pdf' is by far the preferable option. Lines are in general much cleaner and more distinct. Patterns with fine lines look much better. For some reason the difference when it comes to cad-blocks is the most notable, staying clean at 800% whereas the Adobe pdf becomes very jagged and often introduced artifacts, like it doesn't have access to the same data. (Which it may not.)

 

Why it is like this is another question. In some cases, especially with some parallel lines in walls, it looked a bit better with Adobe pdf. Almost as if it was using more antialiasing than the built-in driver and therefore cleaned up some graphics issues. In the end it doesn't matter as the built-in was superior in almost all aspects.

The differences that I've seen are not obvious until compared, but I now find them significant. I made a test print to pdf both on screen and paper in order to compare, and in many cases I felt the difference was even more noticable on paper.

 

Print size on this, admittedly not complete set, was 6.8MB for the Adobe pdf compared to 8.1MB for the built-in, so at least in my case it won't matter. These sizes pass most email systems today and if not I can recommend wetransfer (free up to 2GB).

 

I made some examples of differences between Adobe and the built-in, the built-in is always the example on the right. Zooming varies.

 

This first one shows a break in the wall that isn't even noticable in the Adobe pdf. The built-in shows it the way it looks zoomed in on plan (although hard to see even in plan).

Some drawn lines in layout that became double somehow in the Adobe pdf.

This elevation doesn't differ that much looking on screen, but on print the linework from the built-in pdf was much cleaner and the contrast higher.

Finallý the example I started with, start lines on arrows shows varying linework on Adobe pdf.
