The issue is with "inkscape" not AIPS.  Perhaps you are making the 
output from inkscape way too small or something.  I found another image 
handling task required me to declare that I wanted to edit on a rather 
large scale as I read in the file (600 dots/inch or so) or it 
compromised the plot.

   But you do not need inkscape.  The AIPS PostScript files are the most 
easy to understand PostScript you have ever seen.  There is even a HELP 
POSTSCRIPT file in aips to make suggestions on how to add/change labels, 
arrows, etc

Most people do this with a text editor and gv to confirm that it comes 
out right.
