Very impressive for scrap ply.
As suggested, using dynamic mode or increasing the acceleration will eliminate the dark edges.
My default algorithm already over-scans +1 resolution (without over-scan enabled, or +3 with it) but on some machines it isn't enough so in the next release I will have the option to add a small white border to the image.
I am thinking to make the option for a black border also but I will need to do some testing.
