eliminate the "fog" around things

Alexander's calgary flames had a fog around them - why? when looking how to print from Inkscape I found some info about this... some people called it a "halo"; didn't find out what the solution is.

Materials/Speed/Power settings

• 65/5/500 works for white and brown paper
  • little more oomph, I had to separate some spots manually, but they may have been out of focus

• Styrene "use low frequency like 30 but high speed"
