Alex I imagine that what may be possible is an enlargement of a 35mm or 120 neg onto the likes of X ray or litho film creating a positive then a contact print of that 8x10 film positive onto another sheet of Xray to create a large neg for use with cyanotype paper

Does this sound right?

The cyanotype website which was given as a link gives fairly detailed instructions for the production of such a negative but yes it involves a clear transparency negative made from a scan
