Lusitanos fought valiantly throughout, though, and they finished the stringer of the two sides by scoring a brace of late tries to bring a level of respectability to the scoreline after successive thumpings from London Irish and Stade Francais.
The Portuguese outfit are in their first season of European rugby and are yet to come close to a losing bonus point but they will see this week's fixture as their best chance to get off the mark in one way or another.
They will enter the Round 4 clash wither greater expectation than in their previous home game against London Irish when a shock was never really on the cards, but victory would still be a significant surprise given that Prato ran Stade so, so close in Round 2.
Prato have never won away from home in four seasons of continental competition, though, with 10 games on the road resulting in 10 straight defeats.
As well as losing to London Irish in Reading this term, Prato have been beaten at Grenoble, Stade Francais, London Welsh, Exeter Chiefs, Perpignan, Newport Gwent Dragons, Harlequins, Bayonne and Connacht since their tournament debut in 2010.
