I used to work for a place that sold Copiers.  I sold Lasers, and Computers.
I was told by people whom I trust, that NONE of the photocopiers would
produce an exact 1 for 1 copy.  It was always about 3% off.  This (or so
I was told) is because the treasury department didnot want anyone copying
anything exactly, for fear of counterfitting.  Especialy color copiers.
They would not release color analog copiers period.  You will note that
all of the current color copiers use a glossy toner.  Also mandated by
the treasury department.
