	The machines in current use for photofinishing resemble
the old Integrate To Gray 5-S printers about like vaxen resemble
the first computers.  There are still some of the old printers
left and that may be the source of poor color quality.  For the
record:
	1.  Color is usually not checked in large photofinishing
	    labs at the end.  It cost too much and competition
	    is driving prices down.  If you get a print that is
	    bad, SEND IT BACK.  You become their final inspector
	    and you work cheap.  [Side note, there are still
	    lots of people out there that don't know a color
	    print can be printed in any color desired.]
	2.  Current printers in use scan the negatives, usually
	    in over 100 points.  The resulting matrix is used
	    to color balance the print, computers everywhere.
	    They produce results that are outstanding, at over
	    12000 prints per hour.  One person can run several
	    of the beasts.
	3.  Reprints are sometimes made on older printers, watch
	    the quality of reprints.
	4.  For stable results send your film to a large
	    photofinisher,  find out where your film is going.
	    Remember that stores change their labs rather
	    fast. [And if money is no object use a small local
	    custom lab.]

	Lots of luck.  More information of color balance is easily
found in your local camera shop.  (And there's this great school
in Rochester, N.Y. if you have a year and want to really learn
color.)
