Hi Enrique,
One of the things you can check is your Illustrator file. Be sure to remove any excess points from the file. If you are using “Live Trace” to draw your logo, this can sometimes create a large amounts of unnecessary points. Cleaning up the extra points will help smooth out your logo.
In addition, go to the Object Tab, and under “Object Faceting”, decrease the “Final Object Faceting” setting to “0.1”. This will also help the objects have smoother edges.
Lastly, go to the “Camera Mode” and if you are using the setting “No AntiAliasing”, choose “3×3”. Having No AntiAliasing means the edges of your objects will not be smoothed out. So, be sure to have a setting a 3×3 or better.
Hope this helps.
Best,
Edward
