[PyMOL] image quality

[Chris Rife]

Hi,

I'm using Pymol to make some images for a paper and a poster, and I've 
run across a problem. I can generate images that are beautiful on my 
screen (when ray traced and then viewed as the png file), but when I 
print them out they become extremely grainy. I've tried viewing and 
printing from different programs, but with no luck. Any suggestions?

Thanks,
Chris
