Homebrew PCBs

I have just looked at the film I used and discovered the print may 
have been the wrong way around. I presume the ink should have been 
next to the board, I had this the other way around so the light hit 
the ink printed on the film then had to pass through the transparent 
film itself before hitting the board.
Am I right in thinking this would effect the exposure efficientcy or 
will it not make any difference?
 
 Kind regards
