A3 and A2 prints the design covers the whole area of the paper to the edge  

A3+ the printed area is exactly the same as A3 dimensions only the paper size is slightly lager than standard A3 leaving room for a white border (Preferable for a frame with a mount). 

*Each print is stamped on the back with a custom made logo to show that it is authentic and hasn't been reproduced by someone else.
