Hi Roger,

You could use a Scaled font size instead of an absolute fontsize.
Replacing 18 with something like FontSize -> Scaled[0.06] works for
me.

Another possibility is to scale the font size by 300/72, where 300 is
the resolution you used and 72 pixels per printer point is the size
used for font sizes. So you would use 18 300/72.

Cheers -- Sjoerd
