The Italian police caught several people in Casavatore (near Naples) who were producing counterfeited euro notes ... including the new €20 Europa notes. Here are two articles, one in English, one in Italian:

The second one also has a video that shows some of the fake bills. So far I have not seen any information about the quality of the counterfeits.
