Most banks don't even look at the signature, that is unless the check
> it presented in person at the issuers bank.
This is true, I've had checks go through that weren't signed at all.
I don't think they read anything else (except the dollar amount, and mechanically the routing and account numbers) either, once I mixed up my business and personal deposits (different names, different banks) and all that happened was both banks sent me a "deposit correction" saying that I'd added the total up wrong, and fixing it to the amount they'd actually received.
