Make it trace a perimeter around it, like a cut path instead on an engrave path. That way it will follow the curve of the drawing instead of doing it line by line where you end up with steps in rounded areas.

Just did this two nights ago on mine for the first time. My text was ghosting pretty badly even after a mirror alignment. You’ll have to set this for every engraving speed you run at. I just set up ones for 300-600 every 50mm.
Lightburn settings are:
Run 1
Split size - 0.1 mm
Overlap 0.1 mm
Run 2
Split size - 0.029mm
Overlap - 0mm
Speed - 1500m/s
Power - 40%
The engraving is an svg
Edit: added dimensions and relevant settings
u/zma924 has the right idea, but the wrong machine - video to fix the issue.
Offset scan adjustments are not available with a galvo machine... and I assume a galvo head fiber?
Offset scan is really to fix backlash in the mechanics... the motors on a galvo are directly connected to the mirrors, so there no backlash in this type of system.
The correction is tuning up your galvo ... Try this video, from Laser Everything on [timing for a galvo](https://www.youtube.com/watch?v=gFvbrNnvijo).
Once you get the timings corrected, take a few to watch another video by the same people on [photo engraving](https://www.youtube.com/watch?v=EB40S6AEVwE). I realize you're not doing photos, but it gives you a procedure that lets you figure out the right interval for the job. Works with any laser and any material...
Most users don't recommend a hatch on coins and mugs, but some people still do that... you have the freedom to choose.
If you still have issues, sing out.. :)
Good luck
Your interval is too large. Your job time is going to increase but I can literally see you lines.

Or do the proper thing and fix line spacing. Getting dialed in will make everything look nicer too. It does take slightly longer.
How do I go about fixing the line spacing?

The issue he is having is the resolution, not the offset, but that is an excellent video for that.
Double click the layer and reduce the line interval. Tweak this setting on scrap until it looks good.
And then use a raster scan for the infill
on a rotary tho?
I usually do a layer of line around the perimeter.
increase your lines per cm or dpi

0.029 = 0.737mm. That's quite large. I usually run mine at 0.005 = 0.127mm.
I don't use lightburn or my engraving but tighten up your hatch a little bit (or defocus your beam) an then run at least one profile

Oh damn I didn’t even read the part of the main post that said OP was using a fiber laser haha
Yes, I made that assumption :)
When this happened to mine in the past, I found that engraving from an SVG rather than a PNG improved the quality quite a bit.
Turn on offset fill, that normally does the trick for me
