Narrative:

As we were taxiing out of the FBO ramp area at ewr, we called ground control for taxi instructions. ATC warned us that we were already on an active taxiway. It appeared to us that we were still on the ramp. We did not see any taxi signs that would have indicated to us that we were on a taxiway. We did not cause any traffic conflicts. This situation could have been prevented if the txwys were more clearly marked.
