Hi all, Thanks to wcraig at pruffle.nist.gov (W. Craig Carter) and Bruce Alan Fast <fast at godel.colorado.edu> for their interest. Craig suggested changing the PostScript output itself. Our printer is a HP LaserJet IIISi, which does not seem to convert color graphics to grayscale ones automatically. I have found another interesting method, within Mathematica itself, using the LightSources option. I happen to read that the funny color of normal output is due to the the three light sources. So if we change the color of the light source, the resulting graphic should also change accordingly. If we set the light sources to gray, then the resulting graphic would be gray-scale. Enough said: LightSources -> {{{1.0, 1.0, 1.0}, RGBColor[0.5, 0.5, 0.5]}, ... Other methods would still be appreciated. Mingzuo
