That is one way that I made boards, although I was using photosensitized PCBs. I'd lay them out at 2x or 4x size. I figured out what exact percentage reductions on a particular copy machine, since 50% or 25% were not exact.

I would do the work on blueline graph paper, the lines were a particular blue designed not to show up on photocopiers.

Why would you want to go back to that?
