Ah, but there is a difference here.  Viewing an image doesn't degrade it.
However printing does.  The printing process depletes each pixel of a bit of
the density.  Displaying an image on a monitor is using "additive" colors
whereas printing is "subtractive".  If you print an image enough times, you
will have subtracted all the bits out of the image.

Good grief, and I have to EXPLAIN all this to you guys?
