A nice realism of the Fritzing converter is it takes all the silkscreen text and orients it in the right location for you and in the right size
However, without the right font, your part will default to a rounded sans serif:
You can find the right fonts in the fritzing-app/resources/fonts folder
You can also download the zip with fonts from http://fritzing.org/fritzings-graphic-standards/download-fonts-and-templates
Install all four TrueType (TTF) fonts!
You don't have to regenerate the svg, but you may need to restart inkscape
