I have attached the png file.
To see the blurring effect, increase the zoom. You can see the shady
effects.
How to made the rendering with crispEdges?

    I suspect what you are calling blurring is what is known as
anti-aliasing.  If you set the shape-rendering hint to 'crispEdges' you will
get non-anti-aliased rendering.  However for text at small point sizes this
is usually worse than the anti-aliased rendering.

    Typically for small font-sizes rendering engines either use bitmap
versions of fonts - obviously not possible for SVG - or font hinting where
the outlines of the font are tweaked to lie on pixels - Batik does not
currently support font hinting (it would be very tricky to support given the
complexity of SVG text).

    If suspect that this is not the issue (I'm 99.9% sure it is) you might
send a small sample PNG.
