Make your GeoTIFF from a MAP containing the grid you want and it should turn out just fine. Use the Map/Export... menu and select GeoTIFF as your output type. You will need to play with the resolution to trade off quality vs. file size. I usually end up with around 100 dpi or more if you have a surround you want to make readable - otherwise, for a grid only, much less resolution should do well.
