I cannot name it, but I can show it.

You people probably are aware of this issue, but I wanted to hear from the more experienced users to know how you deal with this annoying problem:
Bad:


Good:


It is especially visible on a white or light background, or when the object is of light color it is visible on dark background maybe. I believe you understood.

I have found two ways to solve that problem:

• Export the SVG in larger dimensions than desired (e.g. 2000), then re-scale the image with the actual desired dimensions (e.g. 800), by using interpolation (e.g. bicubic, bilinear, lanczos). This solution is enough, unless you want to use the SVG in its pure form as input.
  But this will work on plain colors only, as seen on the example above.
  -----
• Put an object behind the drawing, preferably filled with the same color as the object's; so that ugly "empty" space will not appear. This may not be as effective if your object has transparency.

But the second solution involves more work, and your work end up being more complex by adding objects that have a special meaning which could be avoided or not, that is what I want to know.

Thank you for your time! (:

that's probably this FAQ:

Thank you, theozh!

I have found good solutions for the problem.
