I'll try to explain. The 720Softweave is impeccable to be as far as the
artifacts are concerned. The face-hair border looks fine and so do the
shadows under the lower lip and between the lips.

In 1440Enhanced an extra line shows up in the face. It seems tohave
constant distance from the hair. On my monitor, it is about a millimeter
away. The missing yellow in the top could be caused by a printer
problem.

2880x720 shows the extra line on the face at a larger distance and
darker. The missing yellow in the top shows up most clearly here. The
shadows under the lower lips does not look good, but this may be a
gamma/curves problem. But let's disregard this resolution.

1440 High Quality looks okay, but suffers a bit from the wormy textures.
Maybe thowse works are also cousing the other problems I've seen, and I
should switch to adaptive Floyd-Steinberg.
