Well, the final EPS artworks is vector package in format Adobe Illustrator CS2 (You need, at least, Adobe illustrator CS2, or higher,not Pfotoshop!!!)
You can easy change any part on mouse click (first select layer).
EPS file contains three, for five... independent layers.
If you want only logo without any background, just delete layer 'layer 0 backgroudnd' .
Of course vector object 'ib' will be placed on separate layer . ..
