Map print - in progress

I've started work on a sort-of test print. I want to know how some ideas I have for Jim's map print will work out so I'm doing a 'dummy print,' to get a feel for the lay of the land!

This is colour 3 of at least 4. I want to do more layers over the top with details and roads and so-on. I'm basically making it up as I go along and treating this print as an extension of my sketchbook.

Anyone who's done any screenprinting before will no doubt be a-gape at my incredibly high-tech set-up!
