There's another potential complication in the Xerox method, I think. It has been my experience that copy machines frequently distort in one, or both, dimensions. Is this loss of 1:1 scale a problem?? It can be very difficult to notice in copying the printed page, but bothersome when copying things that need to be at the right scale (e. g. maps). Roger rzh@lll-lcc.llnl.gov

That's the reason that I was discussing output from a premium laser prnter, and mentioning that I was twiddling scale factors to keep everything within tolerance. Making the transparency with ThermoFax wouldn't mess up the aspect ratio, because ThermoFax is a contact-printing process.

I am under the impression that this is true by design. A friend of mine was at Xerox when they released their new, highest resolution copier (of the time). They were called in when it was discovered that a dollar bill changer at the campus where one of these copiers had been being beta tested had been accepting copies made by this machine. The solution was to change the scale slightly. By the way, this fellow still has the urge to put an "xc" on a memo instead of a "cc". -- Jack Bonn, <> Software Labs, Ltd, Box 451, Easton CT 06612 uunet!swlabs!jack (UUCP) jack%swlabs.uucp@uunet.uu.net (INTERNET)
