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
