print settings usually consist of outlines, top and bottom layers and infill.

I usually use 3 outlines, 3 top and 3 bottom layers.

But for somethings a single outline works better.

You can also go with no outlines and have everything infill.

this print has 3 outlines.

The slicer considers anything bordering a void to be an edge, so uses outlines.
It could well be the putlines that are causing your ghosting.
If you try it with 1 or 0 outlines, could fix the issue.

All I can think of, either that or something to do with the extrusion process.
