Hard to give a better answer without seeing the plot, but since you're
on Windows, try giving the additional argument type=3D"cairo" to
ggsave(...). Otherwise tiff() uses the old GDI code that doesn't
perform anti-aliasing. The RStudio graphical device is distinct from
tiff() and performs anti-aliasing as well.

(Is is a requirement of your publisher to submit TIFF plots? It may be
possible to preserve them in higher quality as PDF files.)
