Switch to metric.  You can stand a lot closer, your feet stay drier,
and you can keep your vanity "score" the same :-)

I'd be very interested to read more about that, do you have a blog
page or web page showing what you do?  I'm especially interested in
how you get registration between the two sides right.

Have you tried printing on drafting paper?  Drafting paper is
transparent to UV, and I've had good success with it.  I just bought a
pad at the stationery shop.  And just as for transparency, the
printing should go against the board.

You can read about my method with drafting paper here:
