The pdf file contained the board template scaled up 125% and when I printed it I scaled it down to 81% so that the cut marks placed in the pdf by adobe acrobat reader x were visible inside the printable area and not in the margins where they are not printed. 125%*81% gave me the right amount of net scaling I needed. The need for greater than 100% net scaling may be due to my setup (printer etc) so check this for yourselves.
