Sure, for example:
set_plot, 'PS'
device, /color, bits_per_pixel=8, filename=outname+'.ps'
loadct, 13
imdisp, findgen(5,5)
device, /close
If I exlucde the postscipt and plot in an x window I get a 5X5 box
with 25 individual squares. But when I plot to postscript the
individual squares are blended, appearing like a gradient with more
than 25 colors.
