You could always use dry film rather than pre-sensitised, sellers can
supply a length cut from roll, the rolls are 30cm wide which would be
the limit for your long-edge of the board. Use a laminator to apply
it. Laminate a few boards in a run, and store in a dark place until you
need them. Developer is just Sodium Carbonate, a couple of bucks for a
kg at your supermarket would last a long time (mix 20g to 1 liter for
developing).
