Gravitons are to gravitational radiation what photons are to em.
They're emitted only when there is a relative acceleration of masses.
i.e. a static or stationary Black Hole like a Schwarzschild or Kerr (with ang. mom.) hole does not
emit grav. waves. So they're no gravitons coming out.
For that to happen matter should be falling into the Black Hole or you got to have a binary system, where relative acceleration of the masses will lead to a configuration of the masses that changes with time.
"Gravitons" will then come out as a result of the gravitational energy loss of the system.
These efffects will be non local and the radiation should not be interpreted as coming from inside the event horizon...
Hope this helps,
