Thanks for your thoughtful reply. Looking at the file closely in Cura, I see that it is not rounded smooth either. So it appears you've helped me find the source of my problem. Thanks!
Now I'm left to chase a fix.
I am creating the file by using Adobe Illustrator to set some type. Then saving that as a PNG image. The image looks smooth at 100%. Antialiasing of the edges becomes visible when enlarged, as one might expect. I'm creating the image in Illustrator at 100% (i.e. the same size I want printed). So in theory, there should not be artifacts from enlarging.
I'm creating the Cura file by opening the PNG with File > Open, and the resulting Convert Image... dialog.
Perhaps there is something going on with the Cura Convert Image size settings that is causing this? I've tried to find details on the feature, with no luck.
Additional insight or suggestions appreciated!

Caveat: I have never printed ABS. Limitation of 3D printing - no; limitation of Ultimaker 2+ - probably certainly not; Convert image import - no idea what that is but if you have looked closely at the model on the Cura bed and the lines are not wavy then that is what Cura will slice - also look at it in xray view and see if there are any indicated mesh errors.
Adjust layer height - I doubt that will make any difference
Change wall thickness - again doubt it; but your wall thickness should be a multiple of your nozzle diameter, eg 0.8,1.2,1.6 etc. if using a 0.4 nozzle. Not having this will court other problems
Change nozzle - well could be I suppose; not a bad idea but if all your other models are printing straight lines then I doubt it.
Temp settings - two part answer; it would not have been my first thought; but you do have artefacts on your surface which could be caused by a too higher temp. and/or your retraction settings
You do not mention prints speed - if you are printing really fast san 80/90 mm/s + then I wonder.
Looking at your photo my first thought was to think that something was loose, such as your belts, which was causing errors in the positioning of the print head; but you will need an Ultimaker user to help you with diagnosing/fixing that
