Hello Dale and All - I've had good luck dealing with a company that makes blueprints for architects. They can run a bedsheet size drawing through a continuous digital scanner and have prints coming out of a printer at the same time. Prints can be scaled up or down, so you can get prints half the size of a bedsheet or however you'd like. If the original print is, in fact, a 'blueprint' the copies can be made as black lines on a white ground. This saves lots of ink, too. Your friends at OSHA or EPA or wherever outlawed the classic blueprint process (white lines on a blue ground) many years ago because it used ferric sulphate, which they felt was dangerous. Half a century ago
I worked with a continuous type blueprint machine on the Rock Island at Silvis Shops. On Saturdays, if we needed only one or two prints we'd expose the paper then take it over to the slop sink and swab it with the ferric sulphate, using a wad of cotton waste and our bare hands. Guess OSHA was right. I've noticed my hair has turned grey. PAW I deal with Accurate Repro off Ferry Road in Warrenville, Illinois. An armload of prints costs me twenty bucks or so.
