Color question

[rkj(at)dukebar.crml.uab.edu (R. Kyle Justice)]

I have a filled contour plot that I would like to
display with a color bar.  Everything looks fine
on the screen but when I try to print, the colors
on the bar are no longer correct.  They appear
washed out(dithered?).  The contour colors, however,
appear correct.  If I look at the file with
ghostscript, everything looks fine.

I am generating the color bar with TV.  It seems
that the printer is treating a plot and an image
differently.
