I suspect the desire to have color copiers "attended" is more a matter of controlling cost than anything else. I heard some years ago that the Secret Service had asked manufacturers who were working on color copiers to "strut their stuff" and demonstrate the best copies they could make of US currency. The SS was aghast at the results, and I believe these results were at least part of the motivation for the anti-counterfeiting measures recently introduced, such as the microprinting on $50 and $100 bills. There is also alleged to have been an effort by the government to degrade the quality the machines could deliver, or to make "equal size" copying unavailable (and provide only 5% reduction/increase at a minimum). Apparently Xerox said something to the effect of "Nothing doing; we worked for years to get it this good and aren't going to degrade it to solve your problem." Amen. Peter Capek
