RE: [PyMOL] Re: image quality

[DeLano, W. <wa...@su...>]

Image quality:

   As Andrey indicated, on typical color lasers and inkjets, you need =
300 dots per final printed inch (~120 pixels/cm) for maximum quality .  =
A small 4"x3" illustration would need to be 1200x900 pixels ("ray =
1200,900").  Full page 11"x8.5" (ray "3300,2550").  =20

Since rendering those images takes forever and the files get really =
huge, I tend to trade quality for time and space, and stick with 150-200 =
pixels per inch (~60-75 pixels/cm) for draft/in-house printouts.

Cheers,
Warren
