This is a bug in GD2 - When you use Truecolor images with GD2,
anti-aliasing of ttf fonts break. This is fixed in GD-2.0.2. You don't
seem to have all that many colours on those certificates. Try simply
using an indexed image just to see the real quality you can get with
GD+TTF before switching.
The patches to fix this are available privately, but you should bug the
folks at boutell.com to release a new version of GD2.
