Hello, Okke
Ah, the wonders of PostScript! This may or may not be fairly easy. Search for
the word "translate" in your PostScript file; hopefully you will find a line
that looks something like
        3960 601 translate
or
        5.0 inch 8.35 inch translate

These two lines actually are saying the same thing: move so many units in the
x direction and so many units in the y direction. The default units in 
PostScript are "points"; there are 72 points per inch. The first line above is
in points, and the second one is in inches; they both designate the same 
distance. In order to use the inch units, they must be defined in a line prior
to the translate command:
        /inch {72 mul} def
Otherwise you are stuck using points. I almost forgot: these dimensions are
from the lower left corner of the PostScript page. So, to move your logo,
simply alter the values for the translate command.

If you have no translate command already in your file, putting it in the
correct place may be a little tricky. I would suggest searching for the first
"gsave" command, and adding the translate line immediately after it.

If you really want to understand PostScript, there is an Adobe PostScript
Reference Manual, published by Addison-Wesley, I believe. An invaluable tool!

Good luck, and let me know if I can be of further help.
