It appears that your plotting script is changing the thickness of the
contour lines, check your script. You are better off taking the default line
thickness rather then correcting it at the image creation step.

I take the default thickness for the contour lines.

I believe these are a consequence of the way anti-aliasing is implemented.
Anti-aliasing is a perceptual approximation which plays with the
transparency of adjacent pixels to give the illusion of smoothness. Try
playing with the font sizes, the colorbar fonts look "black" on my screen.
 As for the dashed line at the prime meridian, I haven't seen it before. It
is something to be looked at.

You may be able to tweak your plot for optimal results.
