Ghosting occurs when using inkscape to insert a pdf_tex into tex

I use inkscape to make vectorgraph and insert into tex by pdf_tex,the font is a little big when I choose Omit text in pdf and create LaTeX file of Text output options

But there is ghosting when I choose Embed fontsorCovert text to paths

This is my tex code

begin{figure}
    centering
    defsvgwidth{columnwidth}
    input{SM_Join.pdf_tex}
end{figure}

I know i could use scriptsize but I want to know how to resolve this problem.
